sudo pip install-i https://pypi.tuna.tsinghua.edu.cn/simple--no-deps stevedore

sudo pip install-i https://pypi.tuna.tsinghua.edu.cn/simple--no-deps virtualenvwrapper

2、错误2

执行命令 source ~/.bashrc出错：

shuhaishiyi@shuhaishiyi:~$ source~/.bashrc

/usr/bin/python:Nomodule named virtualenvwrapper

virtualenvwrapper.sh:Therewas a problem running the initialization hooks.

IfPythoncouldnotimportthe module virtualenvwrapper.hook_loader,

check that virtualenvwrapper has been installedfor

VIRTUALENVWRAPPER_PYTHON=/usr/bin/pythonandthat PATHis

set properly.

解决办法：“加粗斜体”的部分将ubuntu中路径设置为python3（当py2和py3共存的时候）

在~/.bashrc文件的最下方加入下面语句：

if [ -f /usr/local/bin/virtualenvwrapper.sh ]; then

       export WORKON_HOME=$HOME/.virtualenvs

       export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

       source /usr/local/bin/virtualenvwrapper.sh
