节点包因果报应没有在没有信息的情况下运行

我创建了karma.conf.js文件来运行测试，但它不起作用，终端也没有返回有用的信息。我的文档中没有任何可能引发错误的地方，也没有行号。。。我已经看了两天的文件，找不到可能是什么原因。

这是最终答案：

$ karma start karma.conf.js

这是karma.conf.js文件：

module.exports = function(config) {
    config.set({
    // base path that will be used to resolve all patterns (eg. files, exclude)
        basePath: '../',

        phantomjsLauncher: {

    })
};
