解决办法

修改site-packages/shadowsocks/crypto/openssl.py

1
sudo vim /home/heimo/.local/lib/python2.7/site-packages/shadowsocks/crypto/openssl.py

所有EVP_CIPHER_CTX_cleanup改为EVP_CIPHER_CTX_reset

修改dist-packages/shadowsocks/crypto/openssl.py

1
sudo vim /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py

所有EVP_CIPHER_CTX_cleanup改为EVP_CIPHER_CTX_reset
