You need to install the mysqlnpm module:
您需要安装mysqlnpm 模块：
npm install mysql
npm install mysql
The reason sequelize doesn't have the mysql module as its own dependency is because it can be used with other databases such as postgres or sqlite.
sequelize 没有 mysql 模块作为它自己的依赖项的原因是因为它可以与其他数据库一起使用，例如 postgres 或 sqlite。

For 2017+ users who are using mysql2, the mysqlrequirement was part of Sequelize v3.
对于使用 2017+ 的用户mysql2，该mysql要求是 Sequelize v3 的一部分。
Install v4 of Sequelize (ie. npm i [email protected] --save) and it will work properly with mysql2.
安装 Sequelize 的 v4（即npm i [email protected] --save），它将与mysql2.

I had tried 'npm install mysql' as it is a few times (OCD maybe), but it didn't do the trick. What actually made a difference was the answer by Svagis above:
我试过'npm install mysql'，因为它有几次（可能是强迫症），但它没有成功。实际上有所不同的是上面 Svagis 的回答：
npm install -g mysql
Now I get an access denied error, which is more of a relief because it means progress.
现在我收到一个访问被拒绝的错误，这更像是一种解脱，因为它意味着进步。

As a good practice, it is suggested to keep these library local to the project, so that it can be packaged and installed in other machines by npm.
作为一个好习惯，建议将这些库保存在项目本地，以便通过 npm 打包安装到其他机器上。
