When trying to jump to a function definition: Error: "E484: Can't open file: b' ..."

Tmw commented 4 years ago

The issue

When hovering over a function / module name in vim (nvim) and pressing CTRL + ] to jump to its definition; vim displays an error with the following message:

E484: Can't open file: b'lib/custom_module.ex

which; makes sense since the path is misformed by having a b' as a prefix. The file lib/custom_module.ex is correct. Reproduced it in the debugging setup as described in the Wiki.

Hey! Sorry for the late response. Looks like is related to python2 vs python3

/t/foo $ python3 ~/.vim/pack/minpac/start/alchemist.vim/elixir_sense_client -d./ -c8 -l1 -r definition < sample.exs
b'/private/tmp/elixir-20191106-52993-11bkenu/elixir-1.9.4/lib/elixir/lib/enum.ex:0'⏎                                                                                                           /t/foo $ python ~/.vim/pack/minpac/start/alchemist.vim/elixir_sense_client -d./ -c8 -l1 -r definition < sample.exs

I'll try to comp up with a fix
