Question

环境：运行nodejs映像的Docker容器。

api正常工作。 ts-node-dev运行完美，Express或其他软件包没有问题。数据库也正在工作，我已经通过工作台对其进行了测试。

尝试使用ORM连接到数据库时出现错误。我尝试了其中两个：TypeORM和Sequelize。两者都引发了相同类型的错误：

error TS2307: Cannot find module 'sequelize' or its corresponding type declarations.

我不知道Typescript编译器或docker环境是否有问题。因为只有在我通过docker-compose up在容器内运行应用程序时，这种情况才会发生。

我注意到的是，这两个库都使用库内类型声明，我的意思是，没有@ types / sequelize

这是重现该错误的资源库： https://bitbucket.org/carloseustaquio/test-cicd-docker/src/master/

Answer 1

尝试npm i @types/sequelize获取模块的类型或使用dts-gen生成声明。

打字稿：在Docker容器中找不到模块XWZ或其对应的类型声明
