在 VSTS/Azure DevOps 上构建时出现“npm run build”错误

Question

我有一个 Vue 项目，它在我的机器上编译得很好。今天，我开始在 Azure DevOps 平台上进行部署设置，在调用“npm run build”之前，它似乎运行正常。从那里，我收到多个“ELIFECYCLE”错误，这对我没有多大帮助。 到目前为止我尝试过的：

• 尝试使用npm clean cache 删除 node_modules 和 package-lock.json 并使用 cmd delete remove 命令
• 在 Linux 和 Windows 生产机器上试用

我在这里错过了什么？

Answer 1

最后还是“./Router”下的case问题。仔细一看，日志中写道：

This relative module was not found:
* ./Router in ./src/main.js

这里的第一个问题是这些行在日志文件中没有相互跟随，所以很难解释。

在我的机器上，“./Router”的名称是正确的，但在 repo 上它有一个小写字母，这混淆了构建过程。不过很难追踪。

虽然不是您问题的直接答案，但在处理 Azure DevOps 托管代理上的节点时，我发现我确实遇到了一些随机错误，因此我转而使用容器来构建这些（托管代理内部）以及我的所有错误走了：

jobs:
  - job: build_server
    pool:
      vmImage: 'Ubuntu-16.04'
    steps:
    # build
    - script: |
        docker run -v $(Build.SourcesDirectory):/npm node:10.15 bash \
          -c "cd /npm && npm install && npm run web-build"

    # package
    - task: Docker@1
      inputs:
        containerregistrytype: 'Container Registry'
        dockerRegistryEndpoint: ${{ parameters.registryName }}
        imageName: ${{ format('clarity2/{0}/$(Build.SourceBranchName):$(Build.BuildNumber)', parameters.solutionName) }}
        includeLatestTag: true
        dockerFile: dockerfile
    - task: Docker@1
      inputs:
        containerregistrytype: 'Container Registry'
        dockerRegistryEndpoint: ${{ parameters.registryName }}
        imageName: ${{ format('clarity2/{0}/$(Build.SourceBranchName)', parameters.solutionName) }}
        command: push
