After an OSx update and installing a new version of python 2.7 my virtualevn environment completely broke and I struggled in fixing it. I wasn't sure what caused it and went through a whole set of things that I did and read initially that didn't work are listed below. What solved my problem is provided in the answer section.

• 通过自制软件安装python，然后使用pip安装virtualenv
• 通过 https://www.python.org 安装python，然后使用pip安装virtualenv

• Installed python through homebrew and then used pip to install virtualenv

这并不能完全解决我的问题.只是为了让您了解在找到在OSx上修复python开发环境的正确方法之前我经过了哪些步骤.

Complete manual recovery I went through (What not to do!):

This didn't completely solved my problem. It is just to give you an idea of what steps I went through before I found the correct way to fix my python dev environment on my OSx.

• 使用 Mac OS X 32位i386/PPC安装程序或此处中的说明手动安装virtualenv:

• Removed python 2.7 by using the post in here
• Removed the homebrew installed version
• Installed python through the pkg file in Mac OS X 32-bit i386/PPC installer or Mac OS X 64-bit/32-bit installer

• Manually installed virtualenv following the instructions from here:

 curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-13.1.2.tar.gz
 tar xvfz virtualenv-13.1.2.tar.gz 
 cd virtualenv-13.1.2 
 sudo python setup.py install

通过 https://bootstrap.pypa.io/get-pip.py |须藤python2.7

Manaully install pip through 7: curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | sudo python2.7

在创建了虚拟环境之后，我的pip仍然将软件包安装在主python文件夹中，而不是在虚拟环境和非线程提供了帮助.我的解决方案是在虚拟环境下使用以下选项运行pip: 1-激活虚拟环境，以便设置$VIRTUAL_ENV:

After all this after creating a virtual environment my pip still installed the packages in the main python folder instead of installing them under the virtual environment and non of the threads here neither here helped. My solution to that was to run pip under my virtual env with the following options: 1- Activate the virtual environment so that $VIRTUAL_ENV is set:

source venv/bin/activate

2-强制将pip安装在正确的目的地:

2- Forces pip to install in the right destination:

pip install --target=$VIRTUAL_ENV/lib/python2.7/site-packages   

摘要
