mysql-8.0.22 查询报错

ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client

原因

导致这个错误的原因是，目前，最新的mysql模块并未完全支持MySQL 8的“caching_sha2_password”加密方式，而“caching_sha2_password”在MySQL 8中是默认的加密方式。

解决办法

输入 mysql -u root -p 进入mysql，
mysql> ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘yourpassword’;
Query OK, 0 rows affected (0.12 sec)
