Browserify-shim Poltergeist/Phantom.JS严格模式问题

Question

我正在使用Browserify制作一个Rails project。Bootstrap Javascript通过browserify-shim加载。

当我启动我的项目并在Firefox中查看它时，一切都是正确的。但是，当我通过Poltergeist测试它(或者只是从PhantomJS 2.1.1启动它)时，出现了一个错误：

 Capybara::Poltergeist::JavascriptError:
   One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).                                                                                                                                                          

   ReferenceError: Strict mode forbids implicit creation of global property 'jQuery'
   ReferenceError: Strict mode forbids implicit creation of global property 'jQuery'

下面是问题所在的代码：

;jQuery = global.jQuery = require("jquery");

对我来说，它看起来像是jQuery的填充行(后面有bootstrap.js代码)。

这是我的package.json：

  "name": "billy-bones-rails",
  "version": "0.0.1",
  "description": "Billy-bones-rails asset package",
  "main": "index.js",

  },
  "browser": {
    "bootstrap": "./node_modules/bootstrap/dist/js/bootstrap.js"
  },
  "browserify": {
    "transform": [
      "browserify-shim",
      [
        "babelify",
        {
          "presets": "es2015"
        }
      ]
    ]
  },
  "browserify-shim": {
    "bootstrap": {
      "depends": [
        "jquery:jQuery"
      ]
    }
  }
}

除了禁用Poltergeist错误报告之外，我还能对此错误做些什么吗？

另外，应该注意的是，我只能使用PhantomJS 2.1.1复制这个错误。火狐(46和48)，铬和PhantomJS 1.9.0输出没有错误。

显然，这个问题是由babelify错误配置和browserify-shim造成的。我将以下内容添加到我的babelify配置中：

"ignore": "node_modules"

这摆脱了Bootstrap模块中的顶级严格模式。
