Question

每当我使用outputPath = dist和environment = production构建我的ember项目时，它构建正常但是当我使用outputPath = dist-something和environment = hosted-something构建时，我得到以下错误：

Build failed.

如果有人能让我知道原因是什么以及解决方案，那将会很棒

当uglifyJs解析brocfile.js时似乎是一个错误。由于目前在brcofile.js中我使用以下行

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，当我使用以下订单时，

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

*********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
}

您获得的错误是由于构建尝试在运行“生产”构建时生成源映射。

尝试构建ember js项目时出错
