我的目标是运行可提供Angular前端的nestjs应用。我在项目的根部有一个Angular cli支架应用程序（使用@ angular / cli最新的v8 beta构建）。在此文件夹中，我使用nestjs cli搭建了一个新的nestjs应用程序（应用程序名称为server）。
然后我进入服务器并运行npm run start：prod并得到以下错误：

我正在使用节点版本12的bash（Windows linux子系统）。我没有碰任何东西，两个应用程序都是从CLI重新创建的。
npm运行启动可以正常工作。
当我自己创建一个单独的项目时，nestjs应用程序运行良好，只有当它位于包含有角度应用程序的根目录中时，事情才会出错。 tsconfig文件可能会在父目录中查找并引起问题吗？
答案 0 :(得分：0)
所以我认为打字稿正在跨父目录（显然一直到“ /”）寻找类型是正确的。
我通过将以下命令添加到我的nestjs应用程序tsconfig的CompilerOptions部分中来解决此问题：
"typeRoots": ["./node_modules/@types"],
告诉它仅在该目录中查找键入内容。
