在OSX上出现Python/pip错误

pythonmacos
24

最近我购买了一个新的硬盘并安装了一份干净的OS X Mavericks系统。我使用Homebrew安装了Python，现在需要创建一个Python虚拟环境。但是每当我尝试运行pip命令时，都会收到这个错误信息。我在网上找不到解决此问题的方法，希望能得到任何参考意见。以下是我遇到的错误信息：

如果您需要我提供额外信息，请告诉我。这是我第一次在此发布问题。谢谢。

你需要安装openssl。 - Padraic Cunningham

好的，我发现在线上说这些错误与openssl有关。但我已经安装了openssl。经过更多的研究，我尝试了以下方法并解决了我的问题。如果你也遇到这个错误，这里是我的解决方案。

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

对我来说，brew reinstall python 就足够了（我从 https://dev59.com/N2Ij5IYBdhLWcg3wCxF0 得到了这个方法）。 - Piotr Migdal

在El Capitan上，对于我来说，只需要执行brew link openssl --force（确保首先安装了openssl）就足够了。 - Salyangoz

在OSX 10.11.3上，使用更新的Homebrew（版本>1.0.0，没有git存储库）和Homebrew/homebrew-core（git修订版2775；最后提交于2016-09-22），当我尝试强制链接openssl时，会收到以下错误消息：Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew's openssl. Instead, pass the full include/library paths to your compiler e.g.: -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib``` - Latrunculia
谢谢您，亲切的先生。 - jaredgorski

无效选项：--with-brewed-openssl - Aleksandar Pavić

由于执行 brew link openssl --force 时出现错误，我不得不手动添加库链接以使其运作。

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

上面的brew install openssl解决方案在使用Python 3时没有起作用。然后我意识到我安装的是Python 3.4.2，但是"No HTTPSHandler"异常正在查找/usr/local/Cellar/python3/3.4.1/...。
在删除所有旧的Python 3路径并重新安装virtualenv后，它再次正常工作。
pip3 uninstall virtualenv
pip3 install virtualenv

请注意，install --upgrade 没有生效，需要先卸载。

当我尝试安装pygame时，发现在10.10上出现了同样的错误。通过brew remove python3然后从python.org安装python3.4.2以及active state tcl来解决它。

错误消失了 然后 pip3 install virtualenv

你会收到一个带有brew doctor的消息 警告：Python已安装在/Library/Frameworks/Python.framework下

Homebrew仅支持构建System-provided Python或brewed Python。特别是，安装在/Library下的Python可能会干扰其他软件的安装。

对我来说这并不重要，因为我更喜欢使用python.org的安装方式，这样python在各个平台上都是相同的，而不是在brew中存在差异（之前遇到过问题）。
