PIP was still broken after all this:

在这一切之后，PIP 仍然被打破：

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 hereneither herehelped. My solution to that was to run pip under my virtual env with the following options: 1- Activate the virtual environment so that $VIRTUAL_ENVis set:

在此之后所有的人创造一个虚拟的环境后，我的点子还是在主蟒蛇文件夹安装的软件包，而不是线程的虚拟环境和非下安装它们的位置既不是在这里帮助。我的解决方案是使用以下选项在我的虚拟环境下运行 pip： 1- 激活虚拟环境，以便$VIRTUAL_ENV设置：

source venv/bin/activate

2- Forces pip to install in the right destination:

2- 强制 pip 安装在正确的目的地：

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

After doing brew upgrade pythonmy system python was broken and was throwing fits about virtualenvwrapper.sh, as well as my pipcommand was just suddenly missing. I went to python.org and downloaded the python 2.7.13 installer, ran it, I now have python 2.7.13, pip, and can run pip install virtualenvwrapperand things seem to work.

完成后，brew upgrade python我的系统 python 坏了，并且对 virtualenvwrapper.sh 产生了影响，而且我的pip命令突然丢失了。我去 python.org 下载了 python 2.7.13 安装程序，运行它，我现在有 python 2.7.13，pip，可以运行pip install virtualenvwrapper，一切似乎正常。

Homebrew is an awful, awful, tool.

Homebrew 是一个糟糕的、糟糕的工具。
