在我的 NestJS 项目中，在本地构建和运行是可行的，但是在我的 Azure 管道中构建相同的代码时，由于在命令启动时找不到某些模块，它最近开始失败npm run build。当我在本地运行命令时，没有任何问题并且可以正确构建。
有许多模块可以正确找到（或没有给出错误），那么为什么不呢？您可以在 Imgur 上的此图像中找到我的文件布局图像，并显示相关文件。所有的类都被声明为export class ... {}并且它们中的大多数也被导入到 AppModule 中，它们不会给出错误。
管道布局（相关部分）：
trigger:
- master
- dev
pool:
vmImage: 'ubuntu-latest'
steps:
- task: NodeTool@0
displayName: 'Install Node 12'
inputs:
versionSpec: 12.0.0
- script: |
npm install -g typescript
npm install
npm test
displayName: 'run tests'
- script: |
npm run build
displayName: 'build dist folder'
