Answer 1

只需在//Users/**abc/projectFolder/node_modules/chokidar/lib/fsevents-handler 中删除/关闭下面的代码.js

---

function createFSEventsInstance(path， callback( {

/

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

}

Answer 2

不使用时禁用FsEvents：

• C：\Users\UserName\AppData\Roamingpmode_modules\truffle\build\cli.bundled.js

  如果 (！FsEventsHandler.canUse(((

  opts.useFsEvents = false;

步骤：

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

Answer 3

场景：

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

溶液：

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