升级pip时出错:UnicodeDecodeError:'utf-8'编解码器无法解码字节 [英] Error while upgrading pip: UnicodeDecodeError: 'utf-8' codec can't decode byte

问题描述

我刚刚在Windows 10上安装了python，并且正在尝试升级pip.

I've just installed python on windows 10, and I'm trying to upgrade pip.

我的Windows用户名带有希伯来语字符...

当我尝试运行时:

python -m pip install --upgrade pip

我收到此错误:

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我在想这与希伯来语Windows用户名有关，对吗?

I'm geussing this has to do with my Hebrew windows user name, Is that correct?

我可以在不打开新Windows用户的情况下升级pip吗?

Can I upgrade pip without opening a new windows user?

推荐答案

它看起来像是pip中的错误，它假定其元数据存储为UTF-8. 而是，您的用户名似乎编码为"windows-1255".

It looks like a bug in pip where it's assuming its metadata is stored as UTF-8. Instead, your username appears to be encoded as "windows-1255".

您可以尝试以下操作:

1. 备份C:\Users\עדי\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pip\_vendor\pkg_resources\__init__.py
2. 转到行:1616
3. 将utf-8更改为mbcs.
4. 重新运行升级

1. Backup C:\Users\עדי\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pip\_vendor\pkg_resources\__init__.py
2. Goto line: 1616
3. Change utf-8 to mbcs.
4. Re-run upgrade
