尝试使用命令安装新站点时出现以下错误

bench --site site1.local install-app erpnext

这是运行 Ubuntu 的 Windows Linux SubSostem 上的新安装。

我可以使用root用户和我在安装过程中设置的密码通过命令行登录mysql。

pymysql.err.OperationalError: (2003, “Can't connect to MySQL server on u'localhost' ([Errno 22] Invalid argument)”)

我认为您已启用 mysqld_safe 模式。检查您是否启用了 mysqld_safe 模式：sudo ps -aux | grep "mysqld_safe" 如果它出现在输出结果中，那么您必须使用以下命令禁用它：

停止 mysql 服务并使用 /etc/init.d/mysql start 以正常模式启动它。

为什么您无法使用 Python 客户端连接，因为 root 用户不需要 mysql 密码即可登录 mysql，但由于 mysqld_safe 模式开启，您将无法使用非 root 用户连接它。
