安装帮助文档安装VirtualEnv报错如下
tekiMacBook-Air:workspaces hbai$ source /usr/local/bin/virtualenvwrapper.sh /usr/bin/python: No module named virtualenvwrapper virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly. tekiMacBook-Air:workspaces hbai$ which python /usr/bin/python
检查后发现因为Mac本机自带的python2.7 安装在/usr/bin 下面，但是安装了pycharm后会在/usr/local/bin会有python3.0的执行文件，所以本地的调用基本都被pycharm接管了。
因此给py2.7安装相对应的环境时候，需要通过pycharm来进行安装virtalenv 和 virtualenvwrapper才可以
安装完毕后 再在命令行执行即可
通过这种方式创建的python环境就是3.4的了

注： 如果需要使用mac原先自带的py2.7的环境进行创建virtual env,步骤如下：
需要指定pip3的安装以及设置VIRTUALENVWRAPPER的工作路径，但是不推荐，因为这样运行环境是py2.7的
$ /usr/local/bin/pip3 install virtualenv virtualenvwrapper $ export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 $ source /usr/local/bin/virtualenvwrapper.sh
常用命令：
列出虚拟环境：
$ lsvirtualenv -b
env1
env2切换虚拟环境：
$ workon env1查看环境里安装了哪些包：
$ lssitepackages进入当前环境：
$ cdvirtualenv进入当前环境的site-packages：
$ cdsitepackages
$ cdsitepackages pip复制虚拟环境：
$ cpvirtualenv env1 env3
Copying env1 as env3...退出虚拟环境：
$ deactivate删除虚拟环境：
$ rmvirtualenv env2
Removing env2...
