Can't connect to HTTPS URL because the SSL module is not available

问题：pip install时，报 Can't connect to HTTPS URL because the SSL module is not available

分析：

1. ssl是否安装？brew install openssl显示已安装；

2. ssl是否正常？

    a. python中，import正常

    b. 运行openssl，报以下异常

 dyld: Symbol not found: _d2i_ECPKParameters

  Referenced from: /usr/local/opt/openssl/bin/openssl

  Expected in: /Users/xxx/WorkSpace/STAF/lib/libcrypto.1.0.0.dylib

 in /usr/local/opt/openssl/bin/openssl

zsh: abort      openssl --version

3. 重新编译openssl是否正常？编译后报相同错误，确认为ssl与libcrypto之间问题

You might have come across this error while dealing with the openssl module.

Inorder to solve this issue follow the following steps

Step 1: Install openssl using brew

brew install openssl

Step 2: Copy copy libssl.1.0.0.dylib and libcrypto.1.0.0.dylib

cd /usr/local/Cellar/openssl/1.0.1f/lib

sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/

Note the bold folder name. There will be change in that depending on your openssl version

Step 3: Remove the existing links

sudo rm libssl.dylib libcrypto.dylib

sudo ln -s libssl.1.0.0.dylib libssl.dylib

sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib

That’s it. Now try installing what you have been trying to install.

I hope this helps. If you need any further clarification, do comment.
