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

--------desktop:~$ pip install Django==1.3

我曾经编辑 Modules/setup.dist 文件并取消注释 SSL 代码行并重建它，参考以下线程：http://forums.opensuse.org/english/get-technical-help-here/applications/488962-opensuse-python-openssl-2.html http://forums.opensuse.org/english/get-technical-help-here/applications/488962-opensuse-python-openssl-2.html

OSX + 自制软件用户：

您可以获取菜谱的最新更新：

brew reinstall python

但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它的版本和使用位置：

openssl version -a
which openssl

获取最新的 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：此警告意味着对于其他应用程序，您可能需要使用

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

然后重新编译python：

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

或对于Python 3

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