Troubleshooting

1. cannot import name main

   Trouble: Get error while pip install shadowsocks:

   Traceback (most recent call last):
     File "/usr/bin/pip", line 9, in <module>
       from pip import main
   ImportError: cannot import name main
   

   Fix up:

   1. Modify /usr/bin/pip:

      - from pip import main
      + from pip import __main__
        if __name__ == '__main__':
      -     sys.exit(main())
      +    sys.exit(__main__._main())

   2. That's it! Try again then.

2. undefined symbol: EVP_CIPHER_CTX_cleanup

   Trouble: Get error while ssserver -c /etc/shadowsocks.json -d start

   AttributeError: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup
   

   Fix up:

   1. vi /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py
   2. Type :%s/cleanup/reset/g -> enter (replacing EVP_CIPHER_CTX_cleanup to EVP_CIPHER_CTX_reset)
   3. :wq -> enter. (save file)
