如何在Mac上的python3上使virtualenv工作

Question

我的Mac上有多个python版本。 我想将python3作为默认版本，也想使用virtualenv和virtualenvwrapper。

因此，我在~/.zshrc了别名

alias python='python3'

我也将以下内容添加到了~/.zshrc

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

但是，当我运行mkvirtualenv时，出现以下错误：

▶ mkvirtualenv cv
mkvirtualenv:79: /usr/local/bin/virtualenv: bad interpreter: /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Ver: no such file or directory

即使通过python版本，我也会遇到相同的错误：

▶ mkvirtualenv -p /usr/local/bin/python3 cv
mkvirtualenv:79: /usr/local/bin/virtualenv: bad interpreter: /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Ver: no such file or directory

一些其他命令行输出显示版本和我已经安装的内容：

▶ python --version
Python 3.5.0

▶ echo $VIRTUALENVWRAPPER_PYTHON

这就是/usr/local/bin/virtualenv内容

    sys.exit(

在python 3中使用命令pyvenv 。

例：

pyvenv venv
source venv/bin/activate
