Azure DevOps gulp步骤失败，找不到本地模块 [英] Azure DevOps gulp step fails with Local modules not found

问题描述

我有一个Azure DevOps构建步骤，可为angularjs应用程序运行gulp.我将Gulp文件路径设置为指向 GulpFile.js ，所引用的任务应捆绑该应用程序并将文件放入解决方案文件夹中的zip文件中.当我在Visual Studio中本地运行此程序时，效果很好.

I have a Azure DevOps build step that runs gulp for an angularjs application. I set the Gulp file path to point to the GulpFile.js the referenced task should bundle the app and put the files into a zip file in the solution folder. This works fine when I run this locally in Visual Studio.

在构建过程中出现的错误如下:

The error I am getting during the build is the following:

是否发生此错误，因为Node缺少捆绑应用程序的必要模块.我可以在继续执行任务之前为应用程序进行捆绑任务调用npm install吗?

Does this error occur because Node is missing the necessary modules to bundle the app. Can I make the bundle task call npm install for the app before continueing the task?

推荐答案

您可以添加一个任务，只需在gulp构建之前执行 npm install 即可:

You can add a task just do the npm install before the gulp build:

steps:
- task: Npm@1
  displayName: 'npm install'
  inputs:
    command: install
    workingDir: '$(Build.SourcesDirectory)'
    verbose: false
