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/local/bin/python3 and that PATH is
set properly.

该问题原因：python解释器的路径不正确。

解决方法：
先查看python3的路径

find / -name python3
/usr/bin/python3

vim .bashrc

在末尾添加：
   export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

source .bashrc 运行两次就可以了
