Question

不确定如何开始修复此问题。安装后缺少依赖项。

$ sudo npm install -g browser-sync

npm WARN install Couldn't install optional dependency: Unsupported

到目前为止看起来还不错......但是缺少了一些东西

$ browser-sync --version          
module.js:329
    throw err;
    ^

Error: Cannot find module 'camelcase-keys'
    at Function.Module._resolveFilename (module.js:327:15)
    at Function.Module._load (module.js:278:25)

    at Function.Module._load (module.js:302:12)
    at Module.require (module.js:355:17)

好的，我尝试安装缺少的模块

sudo npm install -g camelcase-keys
/usr/lib
└─┬ camelcase-keys@2.0.0 
  ├── camelcase@2.0.1 
  └── map-obj@1.0.1 

$ browser-sync --version            
module.js:329
    throw err;
    ^

Error: Cannot find module 'map-obj'
    at Function.Module._resolveFilename (module.js:327:15)
    at Function.Module._load (module.js:278:25)
    at Module.require (module.js:355:17)
    at require (internal/module.js:13:17)
    at Object.<anonymous> (/usr/lib/node_modules/camelcase-keys/index.js:2:14)
    at Module._compile (module.js:399:26)
    at Object.Module._extensions..js (module.js:406:10)
    at Module.load (module.js:345:32)
    at Function.Module._load (module.js:302:12)
    at Module.require (module.js:355:17)

缺少另一个模块，这种情况一直在继续。嗯有什么不对？

$ npm -v                
3.3.12

$ node -v
v5.2.0

$ node-gyp -v 
v3.2.1

您的应用是否有package.json？如果有，请转到app文件夹，然后运行命令：

npm install

或sudo npm install

node.js浏览器同步安装
