Answer 1

不使用时禁用 FsEvents：

C:\Users\UserName\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js

// 如果 (!FsEventsHandler.canUse())

opts.useFsEvents = false;

步骤：

truffle compile && truffle build && truffle migrate && truffle serve

Answer 2

只需 remove/off //Users/**abc/projectFolder/node_modules/chokidar/lib/fsevents-handler.js

中的以下代码

函数 createFSEventsInstance（路径，回调）{

//return (new fsevents(path)).on('fsevent', callback).start();

}

Answer 3

场景：

 using create-react-app 
 /Users/**abc/projectFolder/node_modules/chokidar/lib/fsevents-handler.js

解法：

Temporarily //return (new fsevents(path)).on('fsevent', callback).start();
