Question

我刚刚开始尝试从python访问mysql，并选择使用pymysql。但是，在测试连接数据库时，我立即碰壁。代码很简单...

#!/usr/bin/python3
# -*- coding: utf-8 -*-

import pymysql

connection = pymysql.connect(host='localhost', user='root', password='nunya', db='python')

运行此代码时，我得到以下信息...

(base) [me@feynmann mysql]$ ./test-pymysql.py 
Traceback (most recent call last):
  File "./test-pymysql.py", line 6, in <module>
    connection = pymysql.connect(host='localhost', user='root', 
password='nunya', db='python')

line 94, in Connect
    return Connection(*args, **kwargs)

    auth_packet = self._process_auth(plugin_name, auth_packet)
  File "/usr/local/lib/python3.7/site- 
packages/pymysql/connections.py", line 900, in _process_auth
    return _auth.caching_sha2_password_auth(self, auth_packet)
  File "/usr/local/lib/python3.7/site-packages/pymysql/_auth.py", 
line 264, in caching_sha2_password_auth
    data = sha2_rsa_encrypt(conn.password, conn.salt, 
conn.server_public_key)
  File "/usr/local/lib/python3.7/site-packages/pymysql/_auth.py", 
line 142, in sha2_rsa_encrypt
    raise RuntimeError("cryptography is required for sha256_password 
or caching_sha2_password")
RuntimeError: cryptography is required for sha256_password or 
 caching_sha2_password

我已经进行了几次搜索，大部分时间都把我带到这里，但是似乎没有任何意义和/或解决问题的方法。

我也尝试切换到mysql.connector，但是出现了类似但更令人困惑的错误。

我知道这对你们中的大多数人来说似乎很愚蠢，但是我很感谢您提供的任何帮助。

谁能解决“关于pymysql的终极NOOB问题”？
