如何在使用kuduscript将angular4应用程序发布到azure网站时运行postinstall脚本？

Question

我有一个angular4应用程序，是部署到蓝色网页应用(网站)通过配置部署选项通过门户。我使用kuduscript创建自定义部署脚本kuduscript -y –node，然后编辑deploy.cmd来告诉azure如何运行角应用程序。

依赖关系在package.json中进行了调整。prod构建ng build --prod在本地运行良好，但在azure中创建了一个错误：

ng2project@0.0.2 postinstall脚本“节点./node_modules/protractor/bin/webdriver-manager更新”失败 错误:找不到模块'D:\home\site\repository\node_modules\protractor\bin\webdriver-manager‘在Function.Module._resolveFilename .

这是因为postinstall在scripts下的package.json

"scripts": {
  "ng": "ng",
  "build": "ng build",
  "test": "ng test",
  "lint": "ng lint",
  "modernizr": "modernizr -c modernizr-config.json -d src/modernizr.js",
  "postinstall": "node ./node_modules/protractor/bin/webdriver-manager update",
  "e2e": "ng e2e"
}

如果我移除它，构建就很好了。我怀疑这是因为在调用wwwroot之前，文件会从respository文件夹传输到postinstall文件夹。寻找关于如何解决这个问题的指导。

这是正在使用的修改后的deploy.cmd：

Answer 1

这是因为devDependencies，中列出了protractor模块，而使用--production标志运行npm install时，npm将不会安装devDependencies.中列出的模块。

因此，为了避免此错误，您基本上有两个选项：

1. 将devDependencies部分中的"protractor": "5.1.2",移动到dependencies部分。
2. 在步骤2中编辑deploy.cmd脚本以删除--production： 2.如果存在"%DEPLOYMENT_SOURCE%\package.json“，请安装npm包(按下"%DEPLOYMENT_SOURCE%”调用:ExecuteCmd !NPM_CMD！安装IF !ERRORLEVEL！NEQ 0 goto错误弹出)
