Node.js NPM运行监视找不到模块网页

我有一个package.json，其中包含一些包。使用

npm install

后，它将安装所需的所有项目，但也会创建符号链接：

/Users/donny/Sites/Homestead/node_modules/vue -> /usr/local/lib/node_modules/vue

在此之后，我尝试运行

npm run watch

，然后我得到了错误

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: spawn node_modules/webpack/bin/webpack.js ENOENT

有人知道如何解决这个问题吗？
