升级 pip 时出错：UnicodeDecodeError: 'utf-8' codec can't decode byte

Question

我刚刚在 Windows 10 上安装了 python，我正在尝试升级 pip。

我的 Windows 用户名包含希伯来语字符...

当我尝试运行时：

python -m pip install --upgrade pip

我得到这个错误：

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.

我猜这与我的希伯来语 Windows 用户名有关，对吗？

我可以在不打开新的 windows 用户的情况下升级 pip 吗？

Answer 1

它看起来像 pip 中的一个错误，它假设其元数据存储为 UTF-8。 相反，您的用户名似乎被编码为“windows-1255”。

您可以尝试以下方法：

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