错误:请手动安装mysql2包
提问于 2018-05-31 06:16:51
当使用sequalize db:migrate命令时，我得到以下错误。看看之前关于类似问题的一些评论，人们说这是一个依赖问题，但每当我运行
npm安装mysql2
或
npm install -g mysql2
我得到了同样的错误。

所以我终于找到了bug。当你在我的项目中调用sequelize-cli的全局安装的迁移，而不是本地安装的sequelize版本时，这个问题似乎就出现了。我所要做的就是从node modules文件夹中调用脚本，它工作得很好。当我需要以这种方式调用本地安装的软件包node_modules/.bin/sequelize db:migrate时，我以这种方式调用命令sequelize db:migrate
