在执行gulp test-browser命令时,我收到了以下警告消息

WARN [reporter]: Can not load “mocha”,it is not registered!
Perhaps you are missing some plugin?

但如果我执行karma start命令它工作正常,它不会显示任何警告信息.

为什么我收到此警告消息？
我在这里错过了什么？

的package.json

{
'''
 "dependencies": {
    "browser-sync": "^2.9.12","gulp": "^3.9.0","karma": "^0.13.15","karma-mocha": "^0.2.0","mocha": "^2.3.3"
  },"devDependencies": {
    "karma-phantomjs-launcher": "^0.2.1","phantomjs": "^1.9.18"
  }
}

gulpfile.js

gulp.task('test-browser',function () {
var config = {
    configFile: __dirname + '/karma.conf.js',singleRun: true,reporters: ['mocha']
};
var server = new Server(config);
server.start();
});

karma.conf.js

module.exports = function (config) {
config.set({
    browsers: ['PhantomJS'],frameworks: ['mocha'],files: [
        "bower_components/angular/angular.js","bower_components/chai/chai.js","app/**/*.js","test/*.spec.js"
        ]
    });
};

这里的问题是你没有在你的karma.conf.js插件中安装或添加karma-mocha-reporter.

如果你没有安装它.

npm install karma-mocha-reporter --save-dev

并将其添加到您的karma.conf.js插件中.

module.exports = function(config){
config.set({
    plugins:['karma-mocha','karma-phantomjs-launcher','karma-mocha-reporter'],browsers:['PhantomJS'],frameworks:['mocha'],files:[
        "bower_components/angular/angular.js","bower_components/angular-mocks/angular-mocks.js","test/*.js"
    ],colors: true,})
}

它应解决警告并使其正常工作.
