Description Mike Limansky 2020-12-03 10:27:51 UTC
app-vim/vim-latex  failed to emerge after Python 3.8 became a default implementation. Moreover it blocked world update, so I had to unmerge it. It seems like python_single_target_python3_8 is missed for this package.

 The error I got is:

# emerge -pv vim-latex

These are the packages that would be merged, in order:

Unmerging is not the right fix (by the way: always depclean, not unmerge).

You need to set the target in package.use for now as a workaround until it’s added in the ebuild.

Hm. Wait.

The ebuild says:

>PYTHON_COMPAT=( python{3_6,3_7,3_8} )

What's going on here?
