业力无法加载浏览器启动器

Question

arr := make([]int, 0)

reader := bufio.NewReaderSize(os.Stdin, 1024*1024)

for {
    line, _, err := reader.ReadLine()
    if err != nil {
      if err == io.EOF {
        break
      }
      panic(err)
    }


    str := strings.Split(string(line), " ")

    for i:=0; i<len(str); i++ {
        v, _ := strconv.Atoi(str[i])
        arr = append(arr, v)
    }
}
 fmt.Println(arr)

我已经遵循了所有步骤（我知道）：

return response()->noContent();

[launcher]: Cannot load browser "FireFox": it is not registered! Perhaps you are missing some plugin?

npm install karma-firefox-launcher --save-dev

karma.conf.js按预期出现

plugins: [ require('karma-jasmine'), require('karma-firefox-launcher'), require('karma-ie-launcher'), require('karma-jasmine-html-reporter'), require('karma-coverage-istanbul-reporter'), require('@angular-devkit/build-angular/plugins/karma') ],

\node_modules\karma-firefox-launcher\

注意：我没有启动IE浏览器

这可能是一个误导性错误，真正的问题是Karma无法找到Firefox.exe吗？
