osx上的python / pip错误

Question

我最近购买了一个新硬盘并安装了 OS X Mavericks 的全新副本。我使用自制软件安装了 python，我需要创建一个 python 虚拟环境。但是，每当我尝试使用 pip 运行任何命令时，都会出现此错误。我一直无法在网上找到解决此问题的方法。任何参考将不胜感激。这是我得到的错误。

如果您需要我提供任何额外信息，请告诉我，这是我第一次在这里发布问题。谢谢。

Answer 1

好的，我发现 online 这些错误与 openssl 有关。但我已经安装了 openssl。再做一些研究，我尝试了以下方法，它为我解决了这个问题。如果您遇到同样的错误，这是我的解决方案。

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

希望对您有所帮助。

Answer 2

上面的brew install openssl 解决方案不适用于使用 Python 3。然后我意识到我已经安装了 Python 3.4.2，但是在 /usr/local/Cellar/python3/3.4.1/... 中查找“No HTTPSHandler”异常。

删除所有旧的 Python 3 路径并重新安装 virtualenv 后，它再次工作：

pip3 uninstall virtualenv
pip3 install virtualenv

注意install --upgrade不起作用，需要先卸载。

Answer 3

我必须手动添加库链接才能使其正常工作，因为brew link openssl --force 出现错误

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

Answer 4

在 10.10 上尝试安装 pygame 时出现同样的错误。通过 brew remove python3 修复它，然后从 python.org 安装 python3.4.2 以及活动状态 tcl。

错误消失了 然后 pip3 安装虚拟环境

您将收到 brew doctor 的消息 警告：Python 安装在 /Library/Frameworks/Python.framework

Homebrew 仅支持针对系统提供的 Python 或 酿造 Python。特别是，安装到 /Library 的 Python 可能会干扰 与其他软件一起安装。

这对我来说无关紧要，因为我更喜欢安装 python.org，所以 python 在不同平台上是相同的，而不是在 brew 上有所不同（之前遇到过问题）
