我使用节点版本12的Bash(Windows Linux子系统(。我没有触摸任何内容，这两个应用程序都是从CLI创建的。
npm运行启动工作正常btw。
当我自行创建一个单独的项目时，Nestjs应用程序正常工作，只有当它位于包含Angular App的根内部时，DO会出错。tsconfig文件可以在父目录上loking并引起问题吗？
所以我在思考打字稿正在寻找跨父目录的打字(显然是"/"(。
。我通过将以下命令添加到我的Nestjs应用中的TSCONFIG的编译部分：
来解决此问题："typeRoots": ["./node_modules/@types"],
告诉它仅在该目录中查找打字。
