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
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

You need to install the OpenSSL header files before building Python if you need SSL support. On Debian and Ubuntu, they are in a package called libssl-dev. You might need some more dependencies, as noted here.
如果需要 SSL 支持，则需要在构建 Python 之前安装 OpenSSL 头文件。在 Debian 和 Ubuntu 上，它们位于一个名为libssl-dev. 您可能需要一些更多的依赖关系，因为这里要注意。

I was having this problem on Mac OSX, even after confirming my PATH, etc.
我在 Mac OSX 上遇到了这个问题，即使在确认我的 PATH 等之后也是如此。
Did a; pip uninstall virtualenv then install virtualenv and it seemed to works now.
做了一个；pip卸载virtualenv然后安装virtualenv，它现在似乎可以工作了。
At the time I had forced brew to link openssl, unlinked it and virtualenv still seems to work but maybe that's because it was originally linked when I reinstalled it.
当时我强迫 brew 链接 openssl，取消链接它，virtualenv 似乎仍然有效，但也许这是因为它最初是在我重新安装时链接的。

Another symptom of this problem for me was if I went into the python console of my virtualenv and did import sslit would error out. Turns out my virtualenv wasn't using the brewversion of python, just the default install on my machine. No clue why the default install suddenly stopped working, but here's how I fixed it the problem:
对我来说，这个问题的另一个症状是，如果我进入我的 virtualenv 的 python 控制台，import ssl它会出错。原来我的 virtualenv 没有使用brewpython 版本，只是我机器上的默认安装。不知道为什么默认安装突然停止工作，但这是我解决问题的方法：
rmvirtualenv myvirtualenvbrew updatebrew reinstall pythonmkvirtualenv -p /usr/local/Cellar/python/whatever_version_number/bin/python myvirtualenv
rmvirtualenv myvirtualenvbrew updatebrew reinstall pythonmkvirtualenv -p /usr/local/Cellar/python/whatever_version_number/bin/python myvirtualenv

In many cases this is caused by an out of date virtualenv, here's a script to regenerate your virtualenv(s): https://gist.github.com/WoLpH/fb98f7dc6ba6f05da2b8
在许多情况下，这是由过时的 virtualenv 引起的，这里有一个重新生成 virtualenv 的脚本：https: //gist.github.com/WoLpH/fb98f7dc6ba6f05da2b8
Simply copy it to a file (downloadable link above) and execute it like this: zsh -e recreate_virtualenvs.sh <project_name>
只需将它复制到一个文件（上面的可下载链接）并像这样执行它： zsh -e recreate_virtualenvs.sh <project_name>

You can get the latest updates to the recipe:
您可以获得食谱的最新更新：
openssl version -a
which openssl
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:
但是，如果您仍然遇到问题，例如，您可能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使用哪个版本和位置：
brew update
brew install openssl
brew link --overwrite --dry-run openssl # safety first.
brew link openssl --overwrite
To get the latest openssl:
要获取最新的 openssl：
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
This may issue a warning:
这可能会发出警告：
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
Side note: this warning means that for other apps, you may want to use

It seems your piprequires HTTPSHandlerwhich is part of SSLlibrary.
看来您的pip需求HTTPSHandler是SSL库的一部分。

On OS X you should link OpenSSL during Python installation (See: #14497).
在 OS X 上，您应该在 Python 安装期间链接 OpenSSL（参见：#14497）。
For Python 2:
对于 Python 2：
brew reinstall python3 --with-brewed-openssl

You could have multiple Python instances together, to list them run:
您可以将多个 Python 实例放在一起，以列出它们运行：
#make a copy of the existing library, just in case
sudo cp /usr/bin/openssl /usr/bin/openssl.apple
# update openssl
brew update
brew install openssl
brew link --force openssl
# reload terminal paths
hash -r
Or list your version via ls -al /usr/local/lib/python*.
或通过 列出您的版本ls -al /usr/local/lib/python*。

I'm using Redhat and have met the same problem.
我正在使用 Redhat 并遇到了同样的问题。
My solution is :
我的解决方案是：
- install openssl and openssl-devel ---- yum install openssl openssl-devel -y
- install krb5-devel ---- yum install krb5-devel
- change to your python's directory and recompile it ---- make
- 安装 openssl 和 openssl-devel ---- yum install openssl openssl-devel -y
- 安装 krb5-devel ---- yum 安装 krb5-devel
- 切换到你的python目录并重新编译它----make
If I didn't do the 2nd step, when I recompiled my python2.7 , the log would say " fail to build module _ssl".
如果我没有做第二步，当我重新编译我的 python2.7 时，日志会说“无法构建模块 _ssl”。
