karma啟動時出現了很多問題:

1.安裝karma前提條件

2.安裝karma步驟

1).首先執行下面命令:

npm install -g karma

2).安裝karma-cli

$ npm install -g karma-cli

3)安裝外掛:

# Install plugins that your project needs:
$ npm install karma-jasmine karma-chrome-launcher --save-dev

3.karma啟動設定和報錯處理

啟動karma:

karma start

報如下錯誤:

[email protected]:~/develop/angular-phonecat$ karma start

module.js:340
    throw err;
          ^
Error: Cannot find module 'zeparser'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:

    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:

    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:364:17)

解決方法:

sudo npm install zeparser

原因是沒有安裝zeparser,安裝一下就好了.

然後重新配置一下karma,配置步驟如下:

這裡karma init 後會生成karam.conf.js

我們這裡需要修改：files和exclude變數

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine'],
        files: ['*.js'],
        exclude: ['karma.conf.js'],
        reporters: ['progress'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: true,
        browsers: ['Chrome'],
        captureTimeout: 60000,
        singleRun: false
    });
};

然後最好是將karma.conf.js移到/usr/local/lib/node_modules/karma/,這樣啟動時會直接在根目錄查詢karam.conf.js檔案了.

再輸入karma start
