python中插入pymysql

python中插入pymysql出现
"'cryptography' package is required for sha256_password or caching_sha2_password auth methods"
RuntimeError: 'cryptography' package is required for sha256_password or caching_sha2_password auth methods这样的错误

安装cryptography包
pip install cryptography

告诉你需要先安装sha256_password 或者caching_sha2_password
