最近在做一个ambari扩展的项目，用到了brunch来build前端code，在安装完brunch，以及安装完package.json里面的所有依赖后， 仍然出现了这样的错误，有人碰到过吗？ error如下： <pre><code> [root@compute000 ambari-web]# brunch watch --server /usr/local/lib/node_modules/brunch/lib/watch.js:446 throw new Error("You probably need to execute npm install to insta ^ Error: You probably need to execute npm install to install brunch plugins.
