業力無法在Windows上啟動PhantomJS-錯誤：產生未知

Question

我完全不知道這個“未知”錯誤：

karma.conf.js：

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

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

...
browsers: ['PhantomJS'],

錯誤：

我用npm install -g phantomjs安裝了PhantomJS，得到以下輸出：

Looks like an `npm install -g` on windows; unable to check for already installed version.

在啟動測試之前，我嘗試執行以下所示的文件，結果相同：

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

用戶配置文件運行節點：

Users\JINGA4X

與運行幻影的用戶配置文件不匹配：

Users\MYUSER

因此，手動安裝phantom：

• https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-windows.zip

• 將可執行文件解壓縮到C：\\ Users \\ JINGA4X \\ phantomjs

• 通過powershell設置路徑：

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