Angular.js: Error: Module 'MyApp' is not available

Question

我想在我的机器上本地使用 this plunk。但是，当我使用本地 Python 服务器或 http-server 运行时，我不断收到以下错误：

Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due     to:
    Error: [$injector:nomod] Module 'myApp' is not available! You either     misspelled the module name or forgot to load it. If registering a module ensure      that you specify the dependencies as the second argument.

我的 html 文件 如下所示：

<!DOCTYPE html>
<html ng-app="myApp">

  <head lang="en">
    <meta charset="utf-8" />
    <title>Custom Plunker</title>

    </div>
    <div class="drop-container" nv-file-drop nv-file-over uploader="uploader">

      <input type="text" ng-model="tags.size" placeholder="size tag">
    </div>
    <textarea readonly ng-model="json"></textarea>
  </body>

</html>

main.js 文件如下所示：

angular.module('myApp', ['angularFileUpload'])

    if ((arr.length || 0) < 2) {
      return;
    }

    if (!curr.hasOwnProperty(tags.children)) {
      curr[tags.children] = [];
    }

    var elem;    
    if (arr.length == 2) {
      elem = {};
      elem[tags.leaf] = arr[0];
      elem[tags.size] = arr[1];
      curr[tags.children].push(elem);
    } else {
      curr[tags.children].some(function(e) {
        if (e[tags.parent] == arr[0] || e[tags.leaf] == arr[0]) {
          elem = e;
          return true;
        }
      });
      if (!elem) {
        elem = {};
        elem[tags.parent] = arr[0];
        curr[tags.children].push(elem);
      }
      updateTree(elem, arr.slice(1), tags);
    }
  }

  function buildJson(csv, compact, tags) {
    var deferred = $q.defer();

    var result = {};
    result[tags.parent] = 'flare';

    Papa.parse(csv, {
      header: false,
      dynamicTyping: true,
      complete: function(csvArray) {
        csvArray.data.forEach(function(line) {
          if (line.length) {
            updateTree(result, line, tags);
          }
        });
        if (compact) {
          deferred.resolve(JSON.stringify(result));
        } else {
          deferred.resolve(JSON.stringify(result, null, 2));
        }
      }
    });

    return deferred.promise;
  }

  return buildJson;
}])

.controller('MyCtrl', ['$scope', 'FileUploader', 'FlareJson',
function($scope, FileUploader, FlareJson) {
  $scope.csv = "";
  $scope.compact = false;
  $scope.json = "";
  $scope.tags = {
    parent: 'skill',
    children: 'children',
    leaf: 'name',
    size: 'level'
  };

  $scope.uploader = new FileUploader();

  $scope.uploader.onAfterAddingFile = function(fileItem) {
    var reader = new FileReader();
    reader.onloadend = function(event) {
      $scope.$apply(function() {
        if ($scope.append) {
          $scope.csv += event.target.result;
        } else {
          $scope.csv = event.target.result;
        }
      });
    };
    reader.readAsText(fileItem._file);
  };

  function update() {
    FlareJson($scope.csv, $scope.compact, $scope.tags).then(function(json) {
      $scope.json = json;
    });
  }

  $scope.$watchGroup(['csv', 'compact'], update);
  $scope.$watchCollection('tags', update);
}]);

我不明白我做错了什么。我已经搜索过类似的错误信息，但没有找到任何可以帮助我解决问题的信息。

Answer 1

我相信这是因为您在加载 Angular 之前加载了 main.js。尝试将您的脚本放在脚本定义的末尾：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/PapaParse/4.1.1/papaparse.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-file-upload/1.1.5/angular-file-upload.min.js"></script>
<script scr="main.js"></script>

Answer 2

您在 angularjs 文件之前加载脚本文件，这就是您收到此错误的原因。因此，在 "angular.js" 文件之后添加 "main.js" 文件。

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.js"></script>
<script scr="main.js"></script>

Answer 3

哦，解决了！事实证明，main.js 中的以下几行是造成问题的原因：

index.html
main.js
main.css
main.js

我从 main.js 中删除了它们，现在可以使用了 - yuhuu！ :)
