问题描述：

在使用pip安装python软件包时遇到HTTPSHandler错误，以下是堆栈跟踪，

Facing an HTTPSHandler error while installing python packages using pip, following is the stack trace,

我曾经根据以下线程来编辑Modules/setup.dist文件并取消注释SSL代码行并对其进行重建:

I used to edit Modules/setup.dist file and uncomment SSL code lines and rebuilt it, with reference to following thread : http://forums.opensuse.org/english/get-technical-help-here/applications/488962-opensuse-python-openssl-2.html

OSX +自制用户:

您可以获得食谱的最新更新:

OSX + homebrew users:

You can get the latest updates to the recipe:

brew reinstall python

但是，如果您仍然遇到问题，例如也许您已经升级了操作系统，那么您可能需要先获取最新的openssl.您可以从以下位置检查哪个版本以及在哪里使用它:

But if you still get the issue, e.g. maybe you have upgraded your OS, then you may need to get the latest openssl first. You can check which version and where it is used from:

openssl version -a
which openssl

要获取最新的openssl:

To get the latest openssl:

brew update
brew install openssl
brew link --overwrite --dry-run openssl  # safety first.
brew link openssl --overwrite

这可能会发出警告:

bash-4.3$ brew link --overwrite --dry-run openssl
Warning: Refusing to link: openssl 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

旁注:此警告意味着您可能要使用其他应用

Side note: this warning means that for other apps, you may want to use

export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include

然后重新编译python:

Then recompile python:

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

或适用于python 3

or for python 3

brew uninstall python3
brew install python3 --with-brewed-openssl
