错误，而试图构建余烬js项目

Question

每当我构建我的余烬项目与outputPath = dist和环境=生产它构建的很好，但是当我用outputPath = dist-something和environment = hosted-something构建时，然后我得到下面的错误：

Build failed.

将是巨大的，如果有人可以让我知道其中的原因可能是什么，也解决

这似乎是一个错误，当brocfile.js正在uglifyJs解析。由于目前在brcofile.js我使用下面线

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'); 

然而当我使用下面的顺序，

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'); 

误差变

******* **根据评论建议更新整个borc文件******

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(); 

Answer 1

以下内容添加到您的brocfile：

sourcemaps: { 
    enabled: !isProduction 
} 

你所得到的错误是由于构建试图产生sourcemaps，而你正在运行一个“生产”版本。
