我正在尝试安装角度电话猫应用程序并使用karma测试运行器运行测试用例.我安装了节点v0.10.33.我在全球范围内安装了业力.现在,我试图用’npm test’运行测试用例,我得到以下错误：

module.js:340
    throw err;
          ^
Error: Cannot find module 'optimist'
    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:380:17)
    at Object.<anonymous> (C:meangular-phonecatnode_moduleskarmalibcli.j
s:2:16)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:364:17)

任何的想法？我认为可能是业力没有正确初始化我试图运行’karma init’但同样的错误再次.

更新—–

运行’npm install’时出现以下错误：

解决方法

在运行npm install之前尝试执行后续步骤

>从项目中删除文件夹node_modules>运行npm cache clean>运行npm install
