如何修复UnicodeDecodeError：'ascii'编解码器无法解码窗口上的字节

-1

我在Windows 10上使用python 2.7。012'iv'e试图使用“pip install openpyxl” 安装openpyxl，并且iv'e得到了一串错误，以“UnicodeDecodeError：'ascii'编解码器无法解码字节”结尾。我搜索了这个网站的解决方案，我试图升级点，如其中之一所建议的。当我输入“pip安装 - 升级点”我得到了同样的错误（我粘贴错误跟踪下面）。如何修复UnicodeDecodeError：'ascii'编解码器无法解码窗口上的字节

我该如何解决这个问题？

尝试变通办法：'的easy_install --upgrade pip'，看看它的工作原理 –

它可能不适合该编码的问题有所帮助，但升级PIP需要你运行'python -m pip install --upgrade pip'。否则，你会遇到一个错误，试图删除pip.exe。 – eryksun

我发现了这个问题。

我看到最后一个错误来自ntpath，试图使用ascii解码一个字节。这意味着result_path或p_path是不以ascii编码的字符串。

当我打印它们的类型时，它显示result_path是unicode，p_path是一个字符串。当我打印p_path时，我认识到它是用latin1编码的。

所以我取代了线：

result_path = result_path + p_path

到行：

result_path = result_path +解码（p_path， 'LATIN1'）

和解决它：D

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

的路线，

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