Hello LyX users!
I've searched the mailing list archives and found some instructions on
how to change the texlive installation, which LyX uses and added the
following to my `.profile`:
~~~~START~~~~
###################
# texlive manager #
###################
export MY_TEXLIVE_LOCATION="/usr/local/texlive"
export PATH="${MY_TEXLIVE_LOCATION}/2019/bin/x86_64-linux:${PATH}"
#######
# LYX #
#######
# LYX must know where texlive is installed, otherwise it will have limited
functionality.
# prepend web2c path
export TEXMFCNF="${MY_TEXLIVE_LOCATION}/2019/texmf-dist/web2c" # ":${TEXMFCNF}"
# export MANPATH="${MY_TEXLIVE_LOCATION}/2019/texmf-dist/doc/man:${MANPATH}"
# export INFOPATH="${MY_TEXLIVE_LOCATION}/2019/texmf-dist/doc/info:${INFOPATH}"
~~~~~END~~~~~
And it worked great for a day, I got lots of writing done. Then the next
day I restarted my machine and LyX complained about not finding any
textclasses and that it would have limitations.
Whenever I hit Tools > Reconfigure, I get an error on command line output:
~~~~START~~~~
+checking list of textclasses...

It seems like an implementation bug in the script, expecting another
type. I think it could also be Python 2 str VS Python 3 str related.
When I go to Tools > TeX Information, the paths all point to my Guix
profile, instead of the path I defined in the TEXMFCNF environment
variable in my `.profile`. I think that is the reason, why it cannot
find much there. I did not install texlive using Guix, but installed it
by downloading it and installing every single package of the 2019
version using the default installer, which I think in turn uses tlmgr.
My PATH variable starts as follows:
~~~~START~~~~
/home/xiaolong/.nvm/versions/node/v13.9.0/bin:/usr/local/texlive/2019/bin/x86_64-linux:
...
~~~~~END~~~~~
So it is definitely on the path. According to
https://tex.stackexchange.com/questions/454513/how-to-specify-the-path-to-texlive-in-lyx/454523#454523
that should be sufficient, but obviously it is not. It also does not ask
me after a while to restart it or anything, after rescanning in Tools >
TeX Information.
Here is some more system information:
~~~~START~~~~
xiaolong@xlx200:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Trisquel
Description: Trisquel GNU/Linux 8.0, Flidas
Release: 8.0
Codename: flidas
xiaolong@xlx200:~$ which lyx2.3
/home/xiaolong/.guix-profile/bin/lyx2.3
xiaolong@xlx200:~$ which python
/usr/local/bin/python
xiaolong@xlx200:~$ which tlmgr
/usr/local/texlive/2019/bin/x86_64-linux/tlmgr
xiaolong@xlx200:~$ which latexmk
/usr/local/texlive/2019/bin/x86_64-linux/latexmk
~~~~~END~~~~~
Here is a complete log of the output on command line, when I run
`lyx2.3` (it even says, that it will use a wrong texlive):
https://paste.debian.net/1136648/
So at some point my LyX did look at the correct path, but not it is not
and I need to fix it.
What can I do to make LyX pick up the correct texlive installation path?
Best regards,
Zelphir
