Javascript Karma无法在Windows上启动PhantomJS-错误：生成未知

我完全不知道这个“未知”错误：

karma.conf.js:

frameworks: ['mocha', 'should'],

plugins: ['karma-mocha',
          'karma-should',              
          'karma-phantomjs-launcher'],

...
browsers: ['PhantomJS'],

在启动测试之前，我尝试执行如下所示的文件，结果相同：

C:\Users\MYUSER\AppData\Roaming\npm\node_modules\phantomjs\lib\phantom\phantomjs.exe

---

运行节点的用户配置文件：

Users\JINGA4X

与运行幻影的用户配置文件不匹配：

Users\MYUSER

因此，请手动安装幻影：

• 将可执行文件解压缩到C:\Users\JINGA4X\phantomjs

• 通过powershell设置路径：

  [Environment]::SetEnvironmentVariable("PATH", $env:Path + ";C:\Users\JINGA4X\phantomjs", 'User')
