Most likely .bash_profile is not the right startup file for that variable, because it?s only read by login shell. Try putting the same export command in .bashrc, open a new instance (new window or tab) of terminal and see if it works.

Howdy,
Hmmm... if you're using the default shell in Catalina, zsh, .bash_profile, .bashrc and .profile won't be read be default even when using Terminal which is a login shell.
But the direct use as Dick Koch mentioned should still work fine. I've checked it on mys system and I successfully converted a pdf to svg.
Good Luck,

Ettore has been giving good advice on this list recently! However, in this case Doris called dvisvgm by giving it the location of the ghostscript library directly, so PATH variables ought to be irrelevant.
Doris, when you reported the command to us, you used quotation marks around the library path. When I tried this on my machine, I did not use those quotation marks. Did you retry the command by just copying my command and pasting?
Did you look into the location and make sure the library is there?
If so, I give up. After all, I created the install package and I installed on my machine running Catalina and we are running exactly the same command.

The quotes are probably not important, but Dick is right, this may not be a PATH issue at all, rather:
The library name could be incorrect, as it may depend on how ghostscript was installed. Actually, /usr/local/share is a strange location for holding shared libraries. On my system the location is:
/opt/brw/lib//opt/brw/lib/libgs.9.53.dylib
Don?t mind the /opt/brw prefix and replace it with /usr/local. The library name is also different, which may be also an issue here. Taking this difference into account, I was able to run Dick?s example on one of my pdf files.
So, Doris, check for these differences and see if you can run Dick?s example then.
Then there is the separate question of which is the appropriate location for the shell variable to hold the library name to export to the environment. But that is a separate issue.
Hope this helps,

The path posted by Dick Koch is correct when using the installer provided by him which was also used by Doris.

Just a few more comments on this off-topic topic:
1. I agree that installing Anaconda is a great way to have a full Python installation with lots of trimmings. Think of it as TexLive for Python. One of the best things that Anaconda includes is the Jupyter browser-based notebook. It?s great for learning and interactive work.
2. The is clash between MacOS Mojave and Python versions later than 3.7.0, at least with the version installed with Anaconda. This breaks any of the Python features that use TKinter, including the IDLE development environment and the turtles module, for turtle graphics. My understanding is that the clash is fixed in Catalina, but I haven?t tested it myself.
For Mojave, the last version Anaconda that seems to play well with Mojave is:
Anaconda3-5.3.1-MacOSX-x86 64.pkg
You can find an archive of all of the Anaconda installers at:
https://repo.anaconda.com/archive/
3. For a great introduction to Python and programming, I highly recommed:
Downey, A. (2017). Think Python: How to Think Like a Computer Scientist. O?Reilly, 2nd edition. http://greenteapress.com/wp/think-python-2e/
This is a short well-written book with very good exercises. It is available as both an O?Reilly paperback (on the expensive side) or as a free (as in beer) pdf!

A big +1 on the Anaconda distribution.
Completely separate from the old python 2.7 that still ships with Catalina.
Not only it includes most of the packages that you may want to use, like numpy, scipy, sympy, pandas, etc - and you can easily install any others with conda - but it also includes Jupyter Notebook, and a full Python IDE, Spyder, and more (even R Studio, if that is your cup of tea).
Also, it is easy to create separate python environments, so if you want you can test stuff in python 3.8 or 3.9, or run old packages with python 3.5, say, all very seamlessly.

I?m baffled too. I think I have a possible explanation for the first error, but not the second, reproducing Dick?s exact command line.
For what is worth: apparently dvisvgm needs to be told the location of ghostscript?s dylib. This happens by using the command line flag ?libgs or setting the env variable LIBGS (the former overrides the latter). Also apparently dvisvgm does not find libgs.dylib by itself if not told in one of those two ways. Now, at the beginning, if the variable LIBGS, although set in .bash_profile was not picked up, it would have explained the failure, with the caveat that the error message was different.
Just for clarification, Terminal does not run a login shell, unless set in its preferences.
But all this does not explain the error once dvisvgm is run with the correct path put on the command line via ?libgs.
Most of those dylib files are actually symlinks. Is is it possible there?s a problem there? Maybe something went wrong during installation? This is what I have, but I installed ghostscript differently:

Folks,
When Ghostscript is compiled from source, the usual
./configure
make
sudo make install
sequence does not create or install the ghostscript library. The library is created with a special command
make so
and three files are then placed in the folder sobin inside the source directory. Two are symbolic links,
libgs.dylib
libgs.dylib.9
and one is an actual library,
libgs.dylib.9.53
Then there arises the issue of where these three files should be placed. For TeX Live this issue is not very important since only one binary, dvisvgm, uses the library.
MacTeX very deliberately installs nothing in /usr/local/lib because I don'r want to interfere with libraries the user might install there from other places. The Ghostscript install
sudo make install
places the gs binary and many other scripts in /usr/local/bin, but installs everything else in
/usr/local/share/ghostscript/9.53.3
and this folder even contains a subfolder named lib. So that seemed to be a natural place to put the actual dynamic library.
As for symbolic links, I decided to break my own rule and add three links to /usr/local/lib named
libgs.dylib
libgs.9.dylib
libgs.9.53.dylib
I am not wedded to this final piece of the puzzle. Indeed I'd much rather install nothing in /usr/local/lib. And the few people who actually use dvisvgm seem to use the flag and point to the actual location of the library.
All of this does nothing to explain the problem Doris is having. ( Incidentally, I wonder what would happen if she installed our 9.50 package instead, since it also installs a library. After that test, 9.53.3 can be installed again and it will become active.)
I'm just trying to warn us not to get involved with side issues. I hope it helps to know exactly what our package does.

Hi all,
thanks for all the fish. I?ll read your suggestions, try them out this afternoon and keep you up to date with my funny problem ;-)

Folks,
When Ghostscript is compiled from source, the usual
./configure
make
sudo make install
sequence does not create or install the ghostscript library. The library is created with a special command
make so
and three files are then placed in the folder sobin inside the source directory. Two are symbolic links,
libgs.dylib
libgs.dylib.9
and one is an actual library,
libgs.dylib.9.53
Then there arises the issue of where these three files should be placed. For TeX Live this issue is not very important since only one binary, dvisvgm, uses the library.

Hi all,
I repeated the process (hoping that everything just is overwritten and not having to uninstall the ghostscript stuff).
This is the command I entered and the error I got:
dvisvgm --libgs=/usr/local/share/ghostscript/9.53.3/lib/libgs.dylib.9.53 --pdf ct-logo.pdf
ERROR: Ghostscript is required to process PDF files
This is the output of my terminal in the dir named lib:
(base) Doriss-Mac-mini:lib bd$ ls -l l*
-rw-r--r-- 1 root wheel 1468 Oct 7 01:37 landscap.ps
-rwxr-xr-x 1 root wheel 18259520 Oct 7 02:28 libgs.dylib.9.53
-rw-r--r-- 1 root wheel 3736 Oct 7 01:37 lines.ps
(base) Doriss-Mac-mini:lib bd$ pwd
/usr/local/share/ghostscript/9.53.3/lib
(base) Doriss-Mac-mini:lib bd$
The output of list at least shows that there is no symbolic link, but the file is there.
And I found ONE strange thing:
The name of the package I downloaded ends with >>?53.3<<, but the header line of the Installer window ends with >>...53.2-Full<<.
The typo .2 instead of .3 could occur also in other places, right?
Can this be connected to the reason for my problems?

Doris,
I confirmed that my install package puts up a line about Ghostscript 9.53.2 during installation. That is my error, but unfortunately irrelevant and just a spelling error.
Just to check, I removed the entire directory /usr/local/share/ghostscript/9.53.3 from my computer and then reinstalled using the "slightly defective" package. It added 9.53.3 back to the directory.
Then I ran the test of the dvisvgm that I had done earlier. But this time I copied your command out of the latest email and just changed the name of the pdf being converted. The command ran fine.
So the puzzle remains.
I'd like you to do one final test.
https://pages.uoregon.edu/koch <https://pages.uoregon.edu/koch>
download and install Ghostscript 9,50 Full and install it. No need to erase anything first. Then run the test again, this time changing 9.53.3 to 9.50 in appropriate places. Does this work for you?
You can easily return to 9,.53.3 by just installing it again afterward.
Dick Koch
PS: Another test would be to try to convert some other pdf illustration. The dvisvgm error message strongly suggests that this test will also fail, but just to be sure ....

Hi Dick and others,
So the puzzle remains.
I'd like you to do one final test.
https://pages.uoregon.edu/koch
download and install Ghostscript 9,50 Full and install it. No need to erase anything first. Then run the test again, this time changing 9.53.3 to 9.50 in appropriate places. Does this work for you?
I?ll do that. But meanwhile I tried alternatives and wanted to let you know what I came up with and what problem occurred on the way:
install ghostscript via brew
(base) Doriss-Mac-mini:logo bd$ brew link --overwrite ghostscript
Linking /usr/local/Cellar/ghostscript/9.53.3...
Error: Could not symlink share/doc/ghostscript/9.53.3/API.htm
/usr/local/share/doc/ghostscript/9.53.3 is not writable.
So, following this link https://apple.stackexchange.com/questions/192227/how-to-make-files-in-usr-local-writable-for-homebrew
I had to temporarily change the ownership of the folder /urs/local
I changed from root:wheel to me:staff and after I did this, the linking went through:
brew link --overwrite ghostscript
Linking /usr/local/Cellar/ghostscript/9.53.3... 568 symlinks created
after this, I could finally run
dvisvgm --libgs=/usr/local/Cellar/ghostscript/9.53.3/lib/libgs.9.53.dylib ct-logo.dvi
and get my svg.
So could there be some ownership issues while installing with the installer from your page?

Doris,
glad you got it to work.
The ownership is most likely not an issue. When you install HomeBrew it prompts you to change ownership of /usr/local to yourself so that you don?t have to use ?sudo? all the time. The best time to do it is before you install anything else, otherwise you have to do a recursive ?chown -R?, as you have seen from the stackexchange link. By the way, it?s probably better to chown to yourself:wheel, instead of yourself:staff.
Also , brew symlinks into /usr/local, by default, so you would find your library in /usr/local/lib/libgs.9.53.dylib (shorter path).

Doris,
I'm happy you got things to work. Why not just accept the current situation and get on with your life? That's what I intend to do!
A note to others. The Ghostscript we install has been configured specially for TeX. These changes were made after research by Bruno Voisin and others. This is important in the Far East and unimportant for most of us. If you have special TeX needs, there may be a reason to use our install package.
A brief final note.
Apple creates /usr/local, and its permissions, as an empty folder when macOS is installed. This is necessary because even root does not have permission to add things to /usr in modern versions of macOS.
MacTeX is designed to just work with these Apple permissions, since most users do not want to manipulate file permissions.
Sometimes file permissions in /usr/local get changed, either deliberately as done by the brew system, or silently as done by a small number of software installers. Generally such changes make no difference, but diagnosing problems they cause is time consuming and I almost always leave that task to others or to the user.
