pip安装virtualenvwrapper报错的解决办法

1、错误1：

安装virtualenvwrapper报错：

报错内容：

Couldn't find index page for 'pbr' (maybe misspelled?)

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-6hblrn57/virtualenvwrapper/

解决办法：

sudo pip install-i https://pypi.tuna.tsinghua.edu.cn/simple pbr

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

fi

如果还不能解决就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：（我这里直接用pip3从新安装virtualenv和virtualenvwrapper）

1 # Locate the global Python where virtualenvwrapper is installed.
2 if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]
3 then
4     VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"    # 原本是写的\which python，这里贴出来的是我修改为python3后的。
5 fi
