TypeError: Can't mix strings and bytes in path components - PY2 under PY3 #1456

Closed puremourning closed 4 years ago

puremourning commented 4 years ago

First, apologies for the absolute vagueness of this report (i don't have a minimal reproduction script, but i do have a patch, which fixes it for me (tm)).

I have a YCM environment where ycmd (thus Jedi) is being run under python 3, but the jedi enviroment is told to use a python 2.7.5 interpreter. I have found in a particular file that I frequently get failed requests with the following error: TypeError: Can't mix strings and bytes in path components

This is happening with the following backtrace:

But I've also tried master of Jedi and Parso.

Following the traceback, I tried the following patch, which fixed it for my particular case, but i'll be honest when i say it is certainly not canonical and I don't quite understand why it's necessary:

commit 67abd94dd4581bdb52f811f6fac28e8ca85aacba (HEAD -> master)
Author: Ben Jackson <>

Again, apologies for not including a repro, but hopefully this is enough info to repro ?

Thanks for the report! Isn't p = cast_path( p ) good enough?

It's just kind of hard to get the Python2/Python3 conversions all correct. IMO the sys path should probably already be unicode and not bytes.

puremourning commented 4 years ago

It probably is.. I just quickly went for the cast all the things approach and didn’t reduce it cos I was at work and needed a solution :)

davidhalter commented 4 years ago

I just "fixed" it. Since this is Python 2 I don't do proper testing anymore, I pretty much just do whatever it takes to get it work. Python 2 will soon not be supported anymore.

Thanks!
