问题的导致是openssl版本更新，里面的函数却没有跟上版本而造成的。

修改方法：

vim /usr/lib/python3.7/site-packages/shadowsocks/crypto/openssl.py

# 修改地方1， 52行 libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)

改成：libcrypto.EVP_CIPHER_CTX_reset.argtypes = (c_void_p,)

# 修改地方2， 111 libcrypto.EVP_CIPHER_CTX_cleanup(self._ctx) 改成：libcrypto.EVP_CIPHER_CTX_reset(self._ctx)
