macOS默认是Python 2.7。所以需要先安装Python 3.

brew install python3

安装完毕后可以用过python3 -V来验证。

然后安装virtualenv:

pip install virtualenv

完毕后。创建一个基于Python 3的虚拟目录:

virtualenv -p python3 app

激活目录:

source bin/activate

输出:

Python 3.6.3 (v3.6.3:2c5fed86e0, Oct  3 2017, 00:32:08)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
