Latex problems in 2.7.1

[Garrison Taylor]

Hi,

I just updated my Mnemosyne to 2.7.1 on MacOS. Before, I had latex working just fine. After the update, it gives the "Problem with latex. Are latex and dvipng installed?" message. My path variable is still set properly, so that shouldn't be the problem. Any ideas on what the problem could be?

Thanks,
Taylor

Sorry for the late reply here. I didn't change anything related to LaTeX recently. As far as I know, the latest change was to make the Mac code look for LaTeX here:

latex = "/usr/local/bin/latex -output-format=dvi -interaction=nonstopmode"
dvipng = "/usr/local/bin/dvipng -D 200 -T tight tmp.dvi"

I've never actually set it up before myself, and as far as I understand, any changes to the setup break different sets of users. So I'm not really sure what to do.

It looks like on https://mnemosyne-proj.org/help/adding-media.php we suggest downloading MacTex. I'm going to try downloading that from https://www.tug.org/mactex/mactex-download.html and see if I can reproduce/fix the issue.

Hi Taylor,

Are you able to share a few details?

1. What are the contents of the file ~/Library/Mnemosyne/config.py? Specifically the last two lines relating to latex and dvipng

2. What is the location of your LaTeX installation? There are a few ways to install and I'm hoping to replicate the conditions under which you experience this issue

For now, I'm trying with /usr/local/bin/latex as the path, which is the same as the default installer, and using "brew cask install basictex" from https://brew.sh

Hi Devin,

it looks like the problem was that I have latex and dvipng installed to a different local than Mnemosyne was expecting (/Library/TeX/texbin/ instead of /usr/local/bin/). I believe that I had configured this in the past, and then my config.py was reset when I updated Mnemosyne to 2.7.1 (I had some syncing issues that made me have to erase ~/Library/Mnemosyne/). I changed the config.py and it's working for me now.

I installed LaTeX through the CTAN mirror of MacTex (http://mirror.ctan.org/systems/mac/mactex/MacTeX.pkg).

Thanks,

Taylor

Thanks. That confirms my theory. I had changed the path in the default config for a GitHub issue a while back but I think it makes sense to revert that change so that it looks on the default PATH for latex. Then anyone with a strange setup can just change it themselves. I'll do that so in the next release the default will be just "latex" rather than "/usr/local/bin/latex"
