尝试构建 ember js 项目时出错

Error while trying to build ember js project

每当我用 outputPath=dist 和 environment=production 构建我的 ember 项目时,它构建得很好但是当我用 outputPath=dist-something 和 environment=hosted-something 构建时我得到以下错误:

Build failed.

如果有人能告诉我可能的原因以及解决方案,那就太好了

uglifyJs在解析brocfile.js的时候好像报错了。由于目前在brcofile.js我使用下面的行

app.import('bower_components/moment/min/moment.min.js');
app.import('bower_components/jquery-file-upload/js/vendor/jquery.ui.widget.js');
app.import('bower_components/jquery-file-upload/js/jquery.iframe-transport.js');
app.import('bower_components/jquery-file-upload/js/jquery.fileupload.js');

但是当我使用下面的命令时,

app.import('bower_components/jquery-file-upload/js/vendor/jquery.ui.widget.js');
app.import('bower_components/jquery-file-upload/js/jquery.iframe-transport.js');
app.import('bower_components/jquery-file-upload/js/jquery.fileupload.js');
app.import('bower_components/moment/min/moment.min.js');

错误变为

Build failed. Invalid mapping: {"generated":{"line":74174,"column":-50},"source":"bower_components/jquery-file-upload/js/vendor/jquery .ui.widget.js","original":{"line":1,"column":0},"name":null} Error: Invalid mapping: {"generated":{"line":74174,"column":-50},"source":"bower_components/jquery-file-upload/js/vendor /jquery.ui.widget.js","original":{"line":1,"column":0},"name":null} at SourceMapGenerator_validateMapping [as _validateMapping] (C:\wamp\www\PublicMD\EmberMD\Ta\trunk\TextAdminLatestEm ber\node_modules\ember-cli-uglify\node_modules\broccoli-uglify-sourcemap\node_modules\uglify-js\node_modules\source-map\ lib\source-map\source-map-generator.js:272:15)

*********根据评论建议更新整个 borcfile******

var EmberApp = require('ember-cli/lib/broccoli/ember-app');


var isProduction = ['production', 'hosted-something'].indexOf(process.env.EMBER_ENV) > -1;

var app = new EmberApp({

    fingerprint: {
        enabled: false
    },

    hinting: !isProduction,

    minifyCSS: {
        enabled: isProduction
    },

    minifyJS: {
        enabled: isProduction
    },

    storeConfigInMeta: false,

    tests: !isProduction,

    vendorFiles: {        
        'jquery.js': 'bower_components/jquery/dist/jquery.js',

        'handlebars.js': null,

        'ember.js': {
            'hosted-something':  'bower_components/ember/ember.prod.js'
        },

    },

    wrapInEval: !isProduction
});

if (app.env !== 'hosted-something') {
    app.import('bower_components/bootstrap-go/index.css');
    app.import('bower_components/bootstrap-go-responsive/index.css');
}

app.import('bower_components/moment/min/moment.min.js');
app.import('bower_components/jquery-file-upload/js/vendor/jquery.ui.widget.js');
app.import('bower_components/jquery-file-upload/js/jquery.iframe-transport.js');
app.import('bower_components/jquery-file-upload/js/jquery.fileupload.js');

module.exports = app.toTree();

将以下内容添加到您的 brocfile:

sourcemaps: {
  enabled: !isProduction
}

您收到的错误是由于构建在您 运行 "production" 构建时尝试生成源映射。
