Question

我一直致力于在eclipse中获得角度2设置。设置maven时遇到错误。我对maven相对较新，我不确定如何克服错误。任何帮助将不胜感激。

我可以看到的两件事可能是问题，但我不知道如何解决或导致错误的原因：npm ERR! missing script: build＆amp;

package.json文件

{
  "name": "budget_calculator",
  "version": "1.0.0",
  "dependencies": {
    "angular2": "2.0.0-beta.17",
    "es6-shim":"^0.35.0",
    "reflect-metadata":"0.1.2",
    "rxjs":"5.0.0-beta.6",
    "zone.js":"^0.6.12"
  }
}

我用来安装插件的pom.xml部分

Answer 1

您似乎在package.json

中缺少这些依赖项

"dependencies": {
    ...
    "es6-shim":"^0.35.0",
    "reflect-metadata":"0.1.2",
    "rxjs":"5.0.0-beta.6",
    "zone.js":"^0.6.12"
}

您还缺少一个名为build的脚本，您可以在package.json中添加该脚本，因为在您pom.xml中，您有<id>npm run build</id>

{
  ...
  "scripts": {
    "build": "..."
  },
  "dependencies": {
  ...
  }
}

maven-frontend-plugin构建错误
