UnicodeDecodeError在试图升级"pip“或"install pywinusb”时

Question

我正在尝试升级pip，并安装pywinusb，但我得到了一个错误："UnicodeDecodeError：'ascii‘编解码器无法在第8位置解码字节0xe9 :序数不在范围(128)“。

Pip升级：

PS C:\Python27> pip --version
pip 18.1 from c:\python27\lib\site-packages\pip (python 2.7)

PS C:\Python27> python -m pip install --upgrade pip
Collecting pip

You are using pip version 18.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

在"pywinusb“中安装：

PS C:\Python27> pip install pywinusb
Collecting pywinusb
Exception:

在此之前，我已经安装了软件包"pyusb“，没有任何问题，没有任何错误。

我在谷歌搜索过这个错误，但没有得到很好的解释。

如何解决这个错误？

Answer 1

如果您当前的工作目录中有非ASCII的名称( characters.Example )、occurs、if等，则会发生这种情况。将这些名称从目录或文件名中删除，您就可以继续了。

Answer 2

关于这个特殊错误："UnicodeDecodeError：'ascii‘编解码器无法解码位置8的字节0xe9 :序号不在范围(128)“，当试图升级pip或安装任何python数据包时，与用户文件夹名称有关。

我的用户文件夹名是“C:/ user /Sérgio Neves"，而"Sérgio”中的"é“是问题所在，所以我将用户文件夹名改为”C:/ user /SergioNeves“，没有任何重音和空格。

我跟着这个视频来更改文件夹名：rTOA4gXJI
