ember build error: the code generator has deoptimised the styling of as it exceeds the max of 100KB

Question

问题： 1. ember 构建过程以警告结束并以损坏的输出文件告终，该文件在 chromium 客户端上抛出 Uncaught SyntaxError: Invalid or unexpected token，阻止应用程序加载。

症状： 1.“在 bower install bootstrap --save 和必要的 app.import(...) 命令之后，ember 构建过程抛出了几个警告 [BABEL]: the code generator has deoptimised the styling of bower_components/bootsrap/....../jquery.js as it exceeds the max of 100KB，随后是 129 JSHint 错误。

JSHint 错误的前几行：

bower_components/bootstrap/Gruntfile.js: line 8, col 1, 'module' is not defined. bower_components/bootstrap/Gruntfile.js: line 18, col 12, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 19, col 14, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 20, col 32, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 21, col 25, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 28, col 26, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 29, col 32, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 434, col 3, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 435, col 3, 'require' is not defined. bower_components/bootstrap/Gruntfile.js: line 23, col 30, '__dirname' is not defined. bower_components/bootstrap/Gruntfile.js: line 395, col 18, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 441, col 13, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 441, col 38, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 452, col 7, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 458, col 24, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 462, col 14, 'process' is not defined. bower_components/bootstrap/Gruntfile.js: line 466, col 24, 'process' is not defined 17 errors bower_components/bootstrap/dist/js/bootstrap.js: line 8, col 61, Missing semicolon. bower_components/bootstrap/dist/js/bootstrap.js: line 13, col 53, Missing semicolon. bower_components/bootstrap/dist/js/bootstrap.js: line 14, col 59, Expected '===' and instead saw '=='. bower_components/bootstrap/dist/js/bootstrap.js: line 14, col 78, Expected '===' and instead saw '=='. bower_components/bootstrap/dist/js/bootstrap.js: line 15, col 113, Missing semicolon. bower_components/bootstrap/dist/js/bootstrap.js: line 17, col 9, Expected an assignment or function call and instead saw an expression. bower_components/bootstrap/dist/js/bootstrap.js: line 35, col 49, Missing semicolon. bower_components/bootstrap/dist/js/bootstrap.js: line 42, col 6, Missing semicolon.

和指向 'bootstrap' 文件夹（不存在）和 bower_components

中的 'jquery' 文件夹中的文件的类似错误

在没有 bootstrap 的情况下恢复到配置没有解决问题，即使 "bower_components" 中不存在 'bootstrap' 文件夹，构建过程也会抛出相同的错误文件夹
ember-cli-build.js

``

/*jshint node:true*/
/* global require, module */
 var EmberApp = require('ember-cli/lib/broccoli/ember-app');

 module.exports = function(defaults) {
   var app = new EmberApp(defaults, {
     // Add options here
   });                                                                                                                                              

   // Use app.import to add additional libraries to the generated
   // output files.
   //
   // If you need to use different assets in different
   // environments, specify an object as the first parameter. That
   // object's keys should be the environment name and the values
   // should be the asset to use in that environment.
   //
   // If the library that you are including contains AMD or ES6
   // modules that you would like to import into your application
   // please specify an object with the list of modules as keys
   // along with the exports of each module as its value.

 //      app.import('bower_components/bootstrap/dist/css/bootstrap.css');
 //      app.import('bower_components/bootstrap/dist/css/bootstrap-theme.css');
 //      app.import('bower_components/bootstrap/dist/js/bootstrap.js');
     return app.toTree();
 };

文件 ember-client.js 中的结果错误（ember 在 dist 文件夹中构建的编译输出） 在文件的深处隐藏了一行 #!/usr/bin/env node 导致客户端出现问题

    grunt.log.writeln('File ' + rawFilesJs.cyan + ' created.');
    };
  });

  #!/usr/bin/env node 

  define('ember-client/bower_components/bootstrap/grunt/change-version', ['exports'], function (exports) {
    'use strict';

    /* globals Set */
    /*!

快速修复： 1.dist文件夹下编译后的js文件(ember-client.js)存在未捕获的语法错误，去除语法错误(下面代码高亮显示) ) 修复了 'uncaught syntax error' 问题，因此应用可以在浏览器中成功加载。

问题： a) 为什么会这样？ b) 如何永久解决此问题，而无需在每次构建应用程序时手动编辑编译文件？

我查看了其他 Whosebug 讨论，但仍未解决与我的具体案例相关的问题。

您运行陷入了这个问题，因为您正在从 Bower 进行导入。如果你使用这个 Ember 插件，它应该会为你处理一些复杂的导入：https://github.com/ef4/ember-sass-bootstrap

ef4 在 Ember 核心团队中，因此您通常可以信任他的插件。
