如何修復UnicodeDecodeError：'ascii'編解碼器無法解碼窗口上的字節

-1

我在Windows 10上使用python 2.7。012'iv'e試圖使用「pip install openpyxl」安裝openpyxl，並且iv'e得到了一串錯誤，以「UnicodeDecodeError：'ascii'編解碼器無法解碼字節」結尾。我搜索了這個網站的解決方案，我試圖升級點，如其中之一所建議的。當我輸入「pip安裝 - 升級點」我得到了同樣的錯誤（我粘貼錯誤跟蹤下面）。如何修復UnicodeDecodeError：'ascii'編解碼器無法解碼窗口上的字節

我該如何解決這個問題？

嘗試變通辦法：'的easy_install --upgrade pip'，看看它的工作原理 –

它可能不適合該編碼的問題有所幫助，但升級PIP需要你運行'python -m pip install --upgrade pip'。否則，你會遇到一個錯誤，試圖刪除pip.exe。 – eryksun

我發現了這個問題。

我看到最後一個錯誤來自ntpath，試圖使用ascii解碼一個字節。這意味着result_path或p_path是不以ascii編碼的字符串。

當我打印它們的類型時，它顯示result_path是unicode，p_path是一個字符串。當我打印p_path時，我認識到它是用latin1編碼的。

所以我取代了線：

result_path = result_path + p_path

到行：

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

和解決它：D

我的答案（Gal Avineri的答案）幾乎是正確的。您應該轉到ntpath文件並更改該行。

result_path = result_path + p_path

的路線，

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