A friend of mine installed TeX Live 2020 but get error when running
$ texdoc amsmath
texdoc error: No texlive.tlpdb nor shipped tlpdb data found.
Searching on Google doesn't help, so I post this question here.
BTW, I found
/systems/texlive/tlnet/tlpkg/texlive.tlpdb on CTAN root, but I do not know how it can help my friend.
Any clues would be appreciated.
Here is the installation procedure:
- Download texlive2020 distribution from Tsinghua University mirror repository.
sudo ./install.shand wait for the installation to complete
- After installation, import latex into the system path to compile
.texfile in terminal.
After the installation is complete, the texdoc command has no problems. It was just suddenly discovered that it could not be used a few days later.
No config files have been deleted.
