ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/itsdangerous' C

近期练习flask写个blog，

安装flask扩展时

pip install flask-wtf

报error: could not install packages due to an environmenterror: [errno 13] permission denied: '/library/python/2.7/site-packages/itsdangerous' consider using the `--user` option or check the permissions.

如图所示

 

这里报这个错，主要是因为权限不够 ，用下面的命令安装即可

pip install flask-wtf --user

如上图所示

 

这样就安装成功了
