这个错误提示意味着你的Python环境缺少cryptography模块,这个模块是用于处理加密和安全的。为了解决这个问题,你需要安装cryptography模块。可以使用以下命令来安装:
```
pip install cryptography
```
安装完成后,重新运行你的Python程序即可。

RuntimeError: 'cryptography' package is required for sha256_password or caching_sha2_password auth methods
This error occurs when the 'cryptography' package is missing or not installed properly in the system. This package is required for the sha256_password or caching_sha2_password authentication methods to work.
To resolve this error, you can try installing the 'cryptography' package using pip, which is a package manager for Python. Open your command prompt or terminal and enter the following command:
```
pip install cryptography
```
This will install the 'cryptography' package and resolve the error. If you still encounter the error, you may need to check if the package is installed in the correct location or try reinstalling it.
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。
