'cryptography' package is required for sha256_password or caching_sha2_password auth methods
时间: 2023-11-24 07:43:24 浏览: 35
'cryptography' package是用于支持sha256_password和caching_sha2_password这两种认证方法的。如果要使用这两种认证方式,需要安装并配置好'cryptography'包。如果没有安装'cryptography'包或者配置不正确,就会导致报错"RuntimeError: 'cryptography' package is required for sha256_password or caching_sha2_password auth methods"。

python 'cryptography' package is required for sha256_password or caching_sha2_password
回答: 当你在运行Python程序时出现“RuntimeError: ‘cryptography’ package is required for sha256_password or caching_sha2_password auth methods”错误,这通常是因为你的程序使用了pymysql库连接MySQL数据库,并且数据库使用了sha256_password或caching_sha2_password身份验证方法。这些身份验证方法需要cryptography库的支持。[1][2]
另外,如果你在连接MySQL数据库时遇到了pymysql.err.OperationalError: (1130, “host.docker.internal’ is not allowed to connect to this MySQL server”)错误,这通常是因为MySQL服务器不允许来自host.docker.internal的连接。为了解决这个问题,你可以执行以下两行代码:1. update user set Host='%' where User='root'; 2. flush privileges; 这将允许来自任何主机的连接。[3]
所以,要解决这个问题,你需要确保你的Python环境中安装了cryptography库,并且在连接MySQL数据库之前执行了上述的两行代码。这样就可以成功连接数据库并避免出现“RuntimeError: ‘cryptography’ package is required for sha256_password or caching_sha2_password auth methods”错误了。
