Question

我正在使用grunt-karma在PhantomJS浏览器中运行用Jasmine编写的单元测试。我正在测试的代码使用browserify。

当我运行grunt karma时，它会加载我的模块，然后使用Fatal error: write after end输出错误。终端输出如下：

谷歌搜索此错误不会产生任何影响。有没有人对这里发生的事情有任何想法？（如果您需要我提供更多信息，请告诉我。）

当browserify解析规范文件时，第二次调用require时出现相同的错误。

根据this thread的建议，尝试升级您的浏览器安装：

npm install --save-dev browserify@^4.0.0

显示已安装的browserify版本：

$ npm list browserify
app/
├── browserify@4.2.3
├─┬ gulp-browserify@0.4.6
│ └── browserify@3.46.1
└─┬ watchify@1.0.6
  └── browserify@5.13.1

单元测试错误输出“致命错误：写完后”
