For what it's worth, I'm currently working on fixing the pygments issue on nixos. The issue exists because pygments 2.5 uses `PythonLexer` as an alias for `Python3Lexer`, while previously referred to the python2 version. Packages such as ipython and sphinx use PythonLexer, leading to breakage.
I wish they just removed PythonLexer completely, that would've made debugging much easier. -- You received this message because you are subscribed to the Google Groups "sage-release" group.
