Pip 20.2.1 causes UnicodeDecodeError #8717

ha-nso-li · 2020-08-06T01:51:26Z

Environment

pip version: 20.2.1
Python version: Python 3.7.3
OS: Windows 10 Pro 1909

I using venv environment.

My venv path has multi byte character, hangul, i think it may cause error.

Description

Pip 20.2.1 causes UnicodeDecodeError when install some packages. In my case, rope.

But I could downgrade pip to 20.1 using pip. 20.1 has no issue.

There are similar issue. (#8658) But my enviroment is different OS (Win10 vs CentOS) and Python. (3.7 vs 2.7) And traceback is different, too. I think both issues are not same.

Expected behavior

How to Reproduce

Install PIP 20.2.1
Try to install rope

Output

The ticket you linked is a different issue. ~~Is this specific to 20.2.1 (and presumably 20.2.0)? Or does the same happen on 20.1 and earlier?~~ Edit: I missed the line you said 20.1 does not have this issue, sorry.

uranusjr · 2020-08-06T03:26:25Z

OK, I got this one sorted out. The root cause to the error is that pyvenv.cfg is opened with a different encoding from what it is written by venv.

pyvenv.cfg exists before 20.2, however, and is not the reason this pops up now. The trigger is #8695; this code path is not run prior to 20.2, but the redundant dist_is_local check causes pyvenv.cfg to be read, triggering this error when the file has incompatible encoding.

So this exact error should no longer be a problem once #8702 is merged. But the root exception cause remains, and could still be hit in the future in other situations. @hansoli68 would you be able to check what encoding your pyvenv.cfg is written with? PEP 405 does not seem to specify what encoding pyvenv.cfg should be written in, and/or upload the file somewhere?

We’ll need to have a conversation with CPython maintainers (and perhaps also virtualenv maintainers) to clarify this.

uranusjr · 2020-08-06T03:41:52Z

It seems like venv has always used UTF-8 without explicitly specifying it anywhere. I’ll file a PR to fix the encoding.

@uranusjr My pyvenv.cfg is encoded with UTF-8, too. Thanks for your fix.
