Google cloud platform 获得；未处理的拒绝SequelizeConnectionError:connect eNot“；连接到SQL云时

我正在Google App Engine中设置NodeJS后端，当我尝试连接到SQL云（使用sequelize+postgres）时，我遇到以下错误：

Unhandled rejection SequelizeConnectionError: connect ENOENT /cloudsql/tar:us-central1:dbpointofsales/.s.PGSQL.5432

Connect ENOUNT表示系统无法连接到mysql，因为其路径不正确。 使用指定的代码更新models/index.js文件。要找到mysql套接字的路径，请转到文件here/etc/mysql/my.cnf（此路径可能取决于您的服务器）。例如，/etc/my.cnf。在这里，您将找到套接字的路径

请验证，它需要管理权限（ubuntu上的sudo）。 确认登录凭据正确，端口已打开

您必须验证连接的设置，然后您可以尝试确认连接

测试连接

续集

.authenticate（）

.然后（（）=>{

})

.catch（错误=>{

}))

具有密钥socketPath的模块mysql

var sequelize=新的sequelize（“数据库”、用户名、密码、{

    idle: 10000

},

}))

console.error('Unable to connect to the database:', err);
