问题根源
Win10 对 Python 安装位置的系统权限限定问题。
解决方案一
仅安装给 current user 使用
C:\Users\peterpan\Desktop>pip install --user -i https://pypi.tuna.tsinghua.edu.cn/simple/ jinja2
安装包会安装在 C:\Users\peterpan\AppData\Roaming\Python\Python36\site-packages 下。
解决方案二
修改文件夹 C:\Program Files\Python36\Lib\site-packages 权限，让其获得读写权限，然后就可以直接安装
C:\Users\peterpan\Desktop>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ jinja2
安装包会安装在 C:\Program Files\Python36\Lib\site-packages 下。
完。
Win10 环境下 pip 安装失败的问题“Could not install packages due to an EnvironmentError: [WinError 5] 拒绝访问。”
