problems with python and virtualenvwrapper after updating: No module named virtualenvwrapper
提问by mthecreator
I run python 2.7.6 with virtualenv, virtualenvwrapper under ubuntu 14.04.
now i have installed python 2.7.9 from source. the new python interpreter is now located under /usr/local/binbut it seems the old interpreter is also located under /usr/bin.
我在 ubuntu 14.04 下使用 virtualenv、virtualenvwrapper 运行 python 2.7.6。现在我已经从源代码安装了 python 2.7.9。新的Python解释器现在位于下/usr/local/bin，但它似乎老解释也位于下/usr/bin。
if I run python shell it shows up python2.7.9. but if I use mkvirtualenv venvI am getting the following message.
如果我运行 python shell，它会显示 python2.7.9。但如果我使用，mkvirtualenv venv我会收到以下消息。
New python executable in venv/bin/python
Installing setuptools, pip...done.
Blockquote /usr/local/bin/python: No module named virtualenvwrapper
venv/bin/python 中的新 python 可执行文件
安装 setuptools，pip...完成。
Blockquote /usr/local/bin/python: 没有名为 virtualenvwrapper 的模块
old .bashrc(with working configuration using python 2.7.6 interpreter)
旧的.bashrc（使用 python 2.7.6 解释器的工作配置）
# virtualenv-wrappper path
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh
new .bashrc(with failure configuration)
新的.bashrc（带有故障配置）
# virtualenv-wrappper path
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh
with the new .baschrcI type in source .bashrcand get the following output.
使用新的.baschrcI 输入source .bashrc并获得以下输出。
/usr/local/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/local/bin/python and that PATH is set properly.
/usr/local/bin/python：没有名为 virtualenvwrapper 的模块 virtualenvwrapper.sh：运行初始化挂钩时出现问题。
如果 Python 无法导入模块 virtualenvwrapper.hook_loader，请检查是否已为 VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python 安装了 virtualenvwrapper，并且 PATH 设置是否正确。
And I have also tried which -a python:
我也试过which -a python：
output:
输出：
/usr/local/bin/python
/usr/bin/python
I want to use python 2.7.9 with virtualenv and virtualenvwrapper. so what I have to do to get this running ?
我想将 python 2.7.9 与 virtualenv 和 virtualenvwrapper 一起使用。所以我必须做些什么才能让它运行？

You need to install them under python 2.7.9 by specifying the path to correct version of pip to be used
您需要通过指定要使用的正确 pip 版本的路径将它们安装在 python 2.7.9 下
/usr/local/bin/pip install virtualenv virtualenvwrapper
otherwise, when running pip installthe sytem will use the default one (i.e. the one located at /usr/bin/pip)
否则，在运行pip install系统时将使用默认的（即位于/usr/bin/pip）

If you have modified your virtualenvwrapperto point to python3, like I do:
如果您修改virtualenvwrapper了指向python3，就像我一样：
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
then make sure you install the virtualenvand virtualenvwrapperusing:
然后确保安装virtualenv并virtualenvwrapper使用：
sudo /usr/local/bin/pip3 install virtualenv virtualenvwrapper

source /usr/local/bin/virtualenvwrapper_lazy.sh
source /usr/local/bin/virtualenvwrapper_lazy.sh
when use pyenv:
使用 pyenv 时：
export PYENV_ROOT="${HOME}/.pyenv"
if [ -d "${PYENV_ROOT}" ]; then
export PATH="${PYENV_ROOT}/bin:${PATH}"
eval "$(pyenv init -)"
fi
export PATH
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_SCRIPT=/usr/local/bin/virtualenvwrapper.sh
#important
source /usr/local/bin/virtualenvwrapper_lazy.sh
