今天正好新建了一个项目，在用less的时候就各种花样报错提示我：

  

Failed to resolve loader: less-loader
You may need to install it.
Error from chokidar (C:\): Error: EBUSY: resource busy or locked, lstat 'C:\hiberfil.sys'
Error from chokidar (C:\): Error: EBUSY: resource busy or locked, lstat 'C:\pagefile.sys'
Error from chokidar (C:\): Error: EBUSY: resource busy or locked, lstat 'C:\swapfile.sys'

 

Failed to resolve loader: less-loader
You may need to install it.

 

 

Error: Cannot find module 'less'

 

 解决办法：npm install less --save-dev
