Node.js Sequelize 和 MySQL 出现 ETIMEDOUT 错误

Question

我遵循了本教程： https://bezkoder.com/node-js-express-sequelize-mysql/

我的代码是相同的，只是我使用的端口发生了变化，但尽管如此，我还是出现了以下错误：

Server is running on port 3000.
(node:22880) UnhandledPromiseRejectionWarning: SequelizeConnectionError: connect ETIMEDOUT

(Use `node --trace-warnings ...` to show where the warning was created)
(node:22880) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:22880) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

我不明白为什么完全相同的文件对其他人有效，但对我无效。

试试这个代码：

dialectOptions: {
  connectTimeout: 60000
}
