Question

我正在尝试升级pip，还安装pywinusb，但出现错误：“ UnicodeDecodeError：'ascii'编解码器无法解码位置8的字节0xe9：序数不在范围内（128 ）”。

点升级：

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“ pyusb”软件包，没有任何问题，没有任何错误。

我已经在google中搜索了此错误，但没有得到很好的解释。

如何解决此错误？

Answer 1

如果当前工作目录的名称带有非ASCII字符，则会发生这种情况，例如¢，Ë，Ñ，ß等。从目录或文件名中删除这些，就可以了。

Answer 2

关于此特定错误：“ UnicodeDecodeError：'ascii'编解码器无法解码位置8的字节0xe9：序数不在范围（128）中”，在尝试升级pip或安装任何python时数据包，与用户文件夹名称有关。

我的用户文件夹名称是“ C：/ Users /SérgioNeves”，而“Sérgio”中的“é”是问题所在，因此我将用户文件夹名称更改为“ C：/ Users / SergioNeves”重音和空间。

我按照此视频更改了文件夹名称： https://www.youtube.com/watch?v=J_rTOA4gXJI
