Question

我的mac上有几个版本的python。我想像python3一样是默认版本，也想使用virtualenv和virtualenvwrapper。

所以，我在~/.zshrc

中添加了别名

alias python='python3'

我还在~/.zshrc

中添加了以下内容

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

但是，当我运行mkvirtualenv时，我收到以下错误：

▶ 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

即使我传递了python的版本，我也会得到同样的错误：

▶ 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

更多命令行输出显示版本和我已安装的内容：

▶ python --version
Python 3.5.0

这是/usr/local/bin/virtualenv有

的内容

▶ more /usr/local/bin/virtualenv
