UnicodeDecodeError

錯誤資訊：

<span style="font-family:Consolas, Courier New, Courier, mono, serif;"><span style="background-color: rgb(248, 248, 248);"></span></span><pre name="code" class="plain">UnicodeDecodeError: 'ascii' codec can't decode byte 0xcb in position 0: ordinal not in range(128)
 

報錯資訊已經說明是Unicode字元的問題。pip安裝python包時載入使用者目錄，Windows下的環境編碼為GBK，ascii無法編碼。

解決方案：

在python安裝目錄 Python27\Lib\site-packages 建一個檔案sitecustomize.py，內容為

import sys
sys.setdefaultencoding('gb2312')

只管執行“pip install package”，python會自動執行這個檔案。

網上有挺多可用的源的，比如豆瓣：http://pypi.douban.com/simple/， 清華：https://pypi.tuna.tsinghua.edu.cn/simple

Windows下解決方案：

最簡單粗暴的辦法就是在C:\User\youname\pip目錄下新建檔案pip.ini，內容寫上
