This looks like a duplicate of #2501. It appears to be a bug in the lockfile module which pip vendors in. Could you raise a bug against the pylockfile project, and we'll vendor in a new version when they fix it.

[Andrej730]

If someone got the same error - i have described way to solve it in #2501

[nedbat]

@Andrej730 should this still be an open issue for pip?

[Choumingzhao]

I got the same error in Python2.7.13 on Windows 10 with my username setting to Chinese, and the problem is solved with following coding adding to site-packages\pip_vendor\lockfile\__init__.py right after all other import lines.( code are copied from stackoverflow and some small edit)

import sys
# While sys.setdefaultencoding() return "utf-8" in python3 in my PC
# it return "ascii" in python2, so I changed it to OEM(GBK for me)
reload(sys)  # Reload does the trick!
sys.setdefaultencoding('GBK')  #  you could try it with your OEM encoding.

But some packages depends on Microsoft Visual C++ compilers still failed with encoding problem, so I do the same to the file site-packages\setuptools\msvc.py and it worked !

If problems are not solved with the trick above, maybe you can try this.

[pradyunsg]

@pfmoore Would #4486 have fixed this?

[pfmoore]

@pradyunsg I don't think so. As I noted, it's a problem in the lockfile module that needs to be reported to them. There's no indication that I can see that anyone ever did (although there's even a suggested patch noted in the discussion here 😢).

[pradyunsg]

@pfmoore lockfile is now deprecated. We should probably shift to fasteners or something.

[pfmoore]

Probably. I've no feel for how easy that will be to do.

[pradyunsg]

#4766. :)

[gutsytechster]

Is this still valid as #7023 has already been merged? If not, then I think it can be closed :)

[uranusjr]

Maybe? I’ll add an awaiting response label and let the bot close it automatically if no-one raises any objections. Please feel free to respond if the problem still exists.
