【问题描述】：
我有一个管道，它执行npm install，然后是角度构建，最近我添加了一个缓存任务来减轻安装，在开发人员添加一个新的私有依赖项 "runtime-config-loader": "^3.0.0" 之前，它运行良好。
这可能需要再次重新安装 npm，但是，由于某种原因，缓存任务认为它不需要重新安装，因此它会跳过 npm install，然后在 Angular 构建中失败，很可能因为 npm 没有在代理上重新安装。
我禁用了缓存任务并从npm install 任务中删除了自定义条件eq(variables['CACHE_RESTORED'],False)，构建成功。
为什么缓存无法识别需要再次重新安装依赖项？以及如何删除缓存以便再次安装 npm？提醒一下，当我禁用缓存任务并在代理上重新安装 npm 时，构建成功 - 所以这肯定是一个缓存问题。
这是构建 YAML：
steps:
- task: Cache@2
displayName: 'npm Cache'
inputs:
key: 'npm | "$(Agent.OS)" | $(System.DefaultWorkingDirectory)/EE/Angular/package-lock.json'
path: '$(System.DefaultWorkingDirectory)/EE/Angular/node_modules'
cacheHitVar: 'CACHE_RESTORED'
restoreKeys: 'npm | "$(Agent.OS)"'
enabled: false
steps:
- task: Npm@1
displayName: 'npm install'
inputs:
command: custom
workingDir: EE/Angular
verbose: false
customCommand: 'install --legacy-peer-deps'
condition: eq(variables['CACHE_RESTORED'],False)
steps:
- task: Npm@1
displayName: 'npm custom: angular build'
inputs:
command: custom
workingDir: EE/Angular
verbose: false
customCommand: 'run-script build -- --prod'
旧的 package.json 文件，构建 with 缓存可以正常使用：

我理解你为什么这样做，但我认为缓存 node_modules 不是一个好主意。使用
npm ci而不是npm install安装依赖项怎么样？那应该快得多。 -
@JSONDerulo 很有趣，为什么缓存不是一个好主意？安装大约需要 15 分钟，所以微软是推荐我使用缓存任务的人，但我对你的看法很好奇 :) 还有你的意思是什么 npm ci？ npm task 不是 npm ci 吗？
-
@JSONDerulo 好的，所以我只是尝试了
npm ci而不是npm install（只是在 npm 任务中选择了 ci 选项而不是 install 选项）。我确实注意到了改进，但是我什至首先使用缓存的原因是由于某种原因其中一个管道使用 npm install 需要超过 15 分钟，因此 Microsoft 建议使用缓存。我禁用了此管道上的缓存并让npm ci运行，这次安装在 -
添加了答案。但是我仍然认为这不是最好的解决方案。过去，我在 Windows 构建代理上也经历过非常缓慢的 npm 安装。您是否尝试过切换到 linux 代理？这对我们来说要快得多（从 > 10 分钟降至
