由于在ubuntu环境下，将python做与python3.6做了软链接（ln -s python python3.6），并且pip也被我做了软链接，所以导致用pip安装virtualenvwrapper之后，在source启动virtualenvwrapper.sh时以及workon 虚拟环境时总是报错： 

 ./virtualenvwrapper.sh: line : : command not found

 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= and that PATH is

 set properly.

这是根据提示230行的语句： 

 "$VIRTUALENVWRAPPER_PYTHON" -m 'virtualenvwrapper.hook_loader' \

结合错误信息与提示找到的语句，猜测应该是VIRTUALENVWRAPPER_PYTHON这里有问题，然后在virtualenvwrapper.sh文件中查找VIRTUALENVWRAPPER_PYTHON，发现了关键点： 

 # Locate the global Python where virtualenvwrapper is installed.

 if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]

 then

     VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"    # 原本是写的\which python，这里贴出来的是我修改为python3后的。

 fi

VIRTUALENVWRAPPER_PYTHON是用来(Locate the global Python where virtualenvwrapper is installed.)定位哪个python下面安装了virtualenvwrapper的。原本指定的位置是python，也就是2.7版本的。鉴于之前我使用python3.6安装的，所以此处要改成python3。然后这个错误就消失了。

使用virtualenvwrapper的好处是不用每次使用source /xxx/虚拟环境/bin/activate来启动虚拟环境了，在~/.bashrc配置一下，日后开启虚拟环境直接可以用workon命令即可，具体操作步骤，前提是你已经安装了python-virtualenv了： 

# Setup:

#  . Create a directory to hold the virtual environments.

#     (mkdir $HOME/.virtualenvs).

#  . Add a line like "export WORKON_HOME=$HOME/.virtualenvs"

#     to your .bashrc.

#  . Add a line like "source /path/to/this/file/virtualenvwrapper.sh"

#     to your .bashrc.

#  . Run: source ~/.bashrc

#  . Run: workon

#  . A list of environments, empty, is printed.

#  . Run: mkvirtualenv temp

#  . Run: workon

#  . This time, the "temp" environment is included.

# . Run: workon temp

# . The virtual environment is activated.
