Javascript angular2和typescript错误

我正在尝试创建一个angular 2应用程序，并使用hammerjs进行触摸手势。 目前，我正在尝试将来自的quickstarter应用程序与来自的hammerjs应用程序相结合

我一直收到一个错误：

http://localhost:3000/npm:plugin-typescript@4.0.10/lib/plugin.js Failed to load resource: the server responded with a status of 404 (Not Found)
localhost/:33 Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:3000/npm:plugin-typescript@4.0.10/lib/plugin.js

Unable to load transpiler to transpile http://localhost:3000/app/app.component.js

我的systemjs.config.js文件：

(function (global) {
  System.config({
// DEMO ONLY! REAL CODE SHOULD NOT TRANSPILE IN THE BROWSER
transpiler: 'ts',
typescriptOptions: {
  tsconfig: true
},
meta: {
  'typescript': {
    "exports": "ts"
  }
},
paths: {
  // paths serve as alias
  'npm:': 'node_modules'
},
// map tells the System loader where to look for things
map: {
  // our app is within the app folder
  app: 'app',

      }
    }
   });
})(this);

我安装了所有npm安装模块

我缺少什么？

您可能需要这个（来自SystemJS的ypeScript loader文档）：如果您使用的是没有JSPM的SystemJS（您使用的是npm），请为插件typescript和typescript添加SystemJS映射配置：

SystemJS.config({
  packages: {
    "ts": {
      "main": "plugin.js"
    },
    "typescript": {
      "main": "lib/typescript.js",
      "meta": {
        "lib/typescript.js": {
          "exports": "ts"
        }
      }
    }
  },
  map: {
    "ts": "path/to/plugin-typescript/lib",
    "typescript": "path/to/typescript"
  },
  transpiler: 'ts'
});

您是否在命令行上运行了npm安装？package.json文件的内容是什么？它找不到这个库：npm:plugin-typescript@4.0.10/lib/plugin.jsI更新了这个问题。我安装了npm，并且有所有的依赖项。顺便说一句，我的节点\模块/typescript文件夹中没有plugin.js。这是您缺少的库：。这不是typescript库，它是一个第三方库。Claies-我不知道这个插件，现在它已经安装好了，我的System.config设置与这个插件有问题。你能看到应该在那里设置什么吗？如果你真的需要使用缺少的插件，请转到它的github存储库（）并阅读文档。如果你不需要它，请删除system.config.js文件中的行以查看发生了什么。这就是该插件的用途，“SystemJS插件，允许您直接导入System.import TypeScript文件。文件在浏览器中传输，编译错误写入控制台。”
