我有一个小的TypeScript helloworld应用程序,该应用程序使用捆绑文件中的aurelia.io框架,并使用SystemJS进行配置。当我运行我的应用程序时,helloworld.ts的编译后的打字稿版本会引发错误,内容为:

TypeError: define is not a function at System.register.execute
(http://localhost:9000/src/helloworld.js!eval:31:13) at t ...


在我看来,功能define是由SystemJS声明的,所以也许这是一个配置问题。该框架似乎可以很好地加载,但是我发现奇怪的是无法识别systemjs函数。

这是我的项目层次结构和配置文件。我究竟做错了什么?

我的文件夹结构如下所示:

./jspm_packages/...

./scripts/aurelia/aulrelia-bundle.js

./src/main.ts
./src/main.js (compiled ts)
./src/app.ts
./src/app.js (compiled ts)
./src/helloworld.ts
./src/helloworld.js (compiled ts)

./index.html
./config.js


我已经安装了jspm,并按照提示创建了默认的config.js文件。我从默认更改的唯一选项是将babel用作转译器。

我的config.js看起来像这样:

System.config({
  "baseURL": "/",
  "transpiler": "babel",
  "babelOptions": {
    "optional": [
      "runtime"
    ]
  },
  "paths": {
    "*": "*.js",
    "github:*": "jspm_packages/github/*.js",
    "npm:*": "jspm_packages/npm/*.js"
  }
});

System.config({
  "map": {
    "babel": "npm:babel-core@5.5.6",
    "babel-runtime": "npm:babel-runtime@5.5.6",
    "core-js": "npm:core-js@0.9.15",
    "github:jspm/nodelibs-process@0.1.1": {
      "process": "npm:process@0.10.1"
    },
    "npm:babel-runtime@5.5.6": {
      "process": "github:jspm/nodelibs-process@0.1.1"
    },
    "npm:core-js@0.9.15": {
      "fs": "github:jspm/nodelibs-fs@0.1.2",
      "process": "github:jspm/nodelibs-process@0.1.1",
      "systemjs-json": "github:systemjs/plugin-json@0.1.0"
    }
  }
});


我的index.html看起来像这样:

<!DOCTYPE html>

<html lang="en">
<head>
    <meta charset="utf-8" />
    <title>Hello World</title>

    <link rel="stylesheet" type="text/css" href="styles/bootstrap/css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" href="styles/fontawesome/css/font-awesome.min.css">
    <link href="styles/styles.css" rel="stylesheet" />
</head>

<body aurelia-app>
    <div class="splash">
        <div class="message">Welcome...</div>
    </div>

    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
    <script>
     System.config({
       "paths": {
         "*": "*.js"
       }
     });
     //Project uses bundles
     System.bundles["scripts/aurelia/aurelia-bundle"]=["aurelia-bootstrapper"];
     System.import('aurelia-bootstrapper');
   </script>
</body>
</html>


我的helloword.ts看起来像这样:

import {bindable} from 'aurelia-framework';

export class HelloWorld{

  @bindable hello="Hello!";

}

最佳答案

您应该让jspm自动创建config.js文件,并且不要手动对其进行修改。然后,您可以使用aurelia-cli根据通过jspm下载的软件包(如下所示)自动创建捆绑软件:

aureliafile.js

var bundleConfig = {
    js: {
        "scripts/aurelia-bundle-latest": {
            modules: [
                'github:aurelia/*'
            ],
            options: {
                inject: true,
                minify: true
            }
        }
    }
};


这将自动修改config.js以包括捆绑软件所需的文件,并在运行aurelia bundle ---force时在运行时在何处查找它们(强制作用是覆盖以前的捆绑软件)。之后,您的index.html看起来像:

Index.html

<body aurelia-app="path/to/main">
    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
    <script>
        System.import('aurelia-bootstrapper');
    </script>
</body>
