'cryptography' package is required for sha256_password or caching_sha2_password auth methods

发生错误：'cryptography' package is required for sha256_password or caching_sha2_password auth methods

发生错误：'cryptography' package is required for sha256_password or_sha2_password auth methods 是由于在使用sha256_password或caching_sha2_password身份验证方法时缺少了'cryptography'包导致的。

这个错误通常发生在使用MySQL数据库时，当尝试使用sha256_password或caching_sha2_password身份验证方法时，但系统中没有安装'cryptography'包时会出现。

解决这个错误的方法是安装'cryptography'包。可以使用pip命令来安装该包，具体命令如下：

pip install cryptography

安装完成后，再次尝试使用sha256_password或caching_sha2_password身份验证方法，应该就不会再出现该错误了。
