我正在学习本教程http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world/page/5
当我virtualenv flask命令时,我收到此错误消息:
Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
这是有道理的,因为virtualenv的目的是创建一个你可以控制的新环境,--user命令将所有内容放在一个特定的位置,从而破坏开发环境分离的目标.
看来pip默认--user安装,我可以更改此默认行为吗？而且,更好的是,我可以随时获得与virtualenv一起玩的好处吗？
为了澄清,这是我的终端的样子.
