我在阿里云上安装 virtualenvwrapper 配置完bashrc ， source .bashrc 的时候出现如下错误：
[email protected]:~# source ~/.bashrc
/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.
[email protected]:~# pip install virtualenv
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
from pip import main
ImportError: cannot import name main
这里是我 vim .bashrc 后配置的内容（这个配置是错的）：-----------------------------
# enable programmable completion features (you don‘t need to enable
# this, if it‘s already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
#if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
# . /etc/bash_completion
#fi
-------在最后面添加的----------------------------------------
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/workspace
source /usr/local/bin/virtualenvwrapper.sh
分析问题：
python3 -V
python3.5.2
我看了下我的python3 在哪里：
[email protected]:~# which python3
/usr/bin/python3
原来是python3 的路径问题，
解决问题：
[email protected]:~# vim ~/.bashrc
在 打开的bashrc末尾添加如下内容：-----------------------
# Setting PATH for Python 3.5
PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
export PATH
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3.5
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/workspace
source /usr/local/bin/virtualenvwrapper.sh
esc ：x 退出
最后：
source ~/.bashrc
virtualenvwrapper.user_scripts creating /root/.virtualenvs/premkproject
virtualenvwrapper.user_scripts creating /root/.virtualenvs/postmkproject
virtualenvwrapper.user_scripts creating /root/.virtualenvs/initialize
virtualenvwrapper.user_scripts creating /root/.virtualenvs/premkvirtualenv
virtualenvwrapper.user_scripts creating /root/.virtualenvs/postmkvirtualenv
virtualenvwrapper.user_scripts creating /root/.virtualenvs/prermvirtualenv
virtualenvwrapper.user_scripts creating /root/.virtualenvs/postrmvirtualenv
virtualenvwrapper.user_scripts creating /root/.virtualenvs/predeactivate
virtualenvwrapper.user_scripts creating /root/.virtualenvs/postdeactivate
virtualenvwrapper.user_scripts creating /root/.virtualenvs/preactivate
virtualenvwrapper.user_scripts creating /root/.virtualenvs/postactivate
virtualenvwrapper.user_scripts creating /root/.virtualenvs/get_env_details

这样是不是就OK了呀！嘻嘻。
