我最近买了一个新的硬盘，并安装了全新的OS X Mavericks系统。我通过homebrew安装了python，现在需要创建一个python的虚拟环境。但是每次我尝试用pip运行任何命令时，都会出现一个错误。我在网上找不到解决这个问题的方法。如果有人能提供一些参考资料，我会非常感激。以下是我遇到的错误信息。

错误处理 osx 虚拟环境 pip homebrew mavericks

我在10.10版本上安装pygame的时候遇到了同样的错误。解决方法是先用brew删除python3，然后从python.org安装了python3.4.2，并且还安装了active state tcl。

错误解决了，然后我用命令pip3安装了virtualenv。

你会收到一个来自brew doctor的提示，内容是：警告：Python安装在/Library/Frameworks/Python.framework。

Homebrew只支持使用系统自带的Python或者通过brew安装的Python。特别是，安装在/Library的Python可能会干扰其他软件的安装。

对我来说这没关系，因为我更喜欢使用python.org的安装，这样在不同平台上Python的版本是一样的，而不是在brew中有不同的版本（我之前遇到过这个问题）。

我需要手动添加库的链接才能让它正常工作，因为我在使用 brew link openssl --force 时遇到了错误。

brew update    
brew install openssl    
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/    
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
brew uninstall python
brew install python --with-brewed-openssl

上面提到的 brew install openssl 方法在使用 Python 3 时没有奏效。后来我发现我安装的是 Python 3.4.2，但是出现的“No HTTPSHandler”错误却在找 /usr/local/Cellar/python3/3.4.1/... 这个路径。

在删除了所有旧的 Python 3 路径，并重新安装了 virtualenv 之后，它又可以正常工作了：

pip3 uninstall virtualenv
pip3 install virtualenv

需要注意的是，install --upgrade 这个命令没有用，必须先卸载旧版本。

好的，我在网上发现这些错误和openssl有关。但我已经安装了openssl。经过进一步的研究，我尝试了以下方法，结果解决了我的问题。这里是我的解决方案，以防你也遇到同样的错误。

brew install openssl
brew link openssl --force
brew uninstall python
brew install python --with-brewed-openssl
