After updating some packages I am receiving this error:
Error: can't read "::active_cls": no such variable
How can this be corrected? I uninstalled TeX Live and reinstalled, and received the same error.
Thanks to David Carlisle, I was able to use the link he provided to do a quick patch of the files. Below are the steps to follow to fix the issue:
I had the same error when trying to run TeXLive manager. It was solved by updating the manager through command line by the command
tlmgr update --self
If the above command does not solve the problem, try the following command
tlmgr update --all
this should clear and update the error causing packages.
I assume the problem occurs only with the GUI
tlshell (Tcl/Tk-based) for tlmgr.
If you have java, I think the java-based
tlcockpit (another GUI for tlmgr) under the directory
\texlive\2019\texmf-dist\scripts\tlcockpit\tlcockpit.jar might be a better alternative.
Hope it helpful :)
