問題根源

Win10 對 Python 安裝位置的系統權限限定問題。(導致此問題的原因是，安裝 Python 時沒有勾選 Install for all users)

 

解決方案一

僅安裝給 current user 使用

C:\Users\peterpan\Desktop>pip install --user -i https://pypi.tuna.tsinghua.edu.cn/simple/ jinja2

安裝包會安裝在 C:\Users\peterpan\AppData\Roaming\Python\Python36\site-packages 下。

 

解決方案二

修改文件夾 C:\Program Files\Python36\Lib\site-packages 權限，讓其獲得讀寫權限，然后就可以直接安裝

 

 

 

 

 

 

 

 

 

 

C:\Users\peterpan\Desktop>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ jinja2

安裝包會安裝在 C:\Program Files\Python36\Lib\site-packages 下。

 

完。
