Question

我在Windows 10上使用python 2.7。 iv尝试使用＆＃34; pip install openpyxl＆＃34;安装openpyxl。并且我得到了一些错误，以＆＃34; UnicodeDecodeError结尾：＆＃39; ascii＆＃39;编解码器不能解码字节＆＃34;。我搜索了这个网站的解决方案，我试图升级pip，正如其中一个建议的那样。当我键入＆＃34; pip install --upgrade pip＆＃34;我得到了同样的错误（我粘贴了下面的错误跟踪）。

C:\Users\Gal>pip install --upgrade pip

UnicodeDecodeError: 'ascii' codec can't decode byte 0xee in position 0:   
ordinal not in range(128)

我该如何解决这个问题？

Answer 1

我发现了问题。

我看到最后一个错误来自ntpath，尝试使用ascii解码一个字节。这意味着result_path或p_path都是未在ascii中编码的字符串。

当我打印他们的类型时，它显示result_path是unicode，p_path是一个字符串。当我打印p_path时，我发现它是用latin1编码的。

所以我换了一行：

result_path = result_path + p_path

到该行：

result_path = result_path + decode（p_path，'latin1'）

并解决了它：D

Answer 2

我的答案（Gal Avineri的答案）几乎是正确的。您应该转到ntpath文件并更改该行。

result_path = result_path + p_path

到该行，

result_path = result_path + p_path.decode('latin1')

Answer 3

以上答案为我提供了正确的线索，但没有一种解决方案对我有用。事实证明，由于Windows用户名中的“å”，我遇到了问题。

我将行更改为：

result_path = result_path + p_path.encode('utf-8')
