"node run dev" can't work ,how to fix it?

Question

I want to run "truffle serve" which linked to localhost:8080. But get this error message

Then I tried to find the problem which may be the version of truffle. I tried "npm run dev". But failed with this message.

How can I solve the problem?, please help me.

`dev` in this scenario is the name of a property in the `scripts` object of your `package.json`. Obviously this property has not been defined. — connexo, Dec 31 '17 at 10:23

Add this to the scriptssection in your package.json:

"scripts": {
   "dev": "truffle serve",
   // other scripts that may already be defined here
}

This allows you to execute truffle serve by issueing npm run dev.

Regarding your fsevents is not a constructor problem, please refer to

https://github.com/trufflesuite/truffle/issues/463

which suggests that issueing

truffle init webpack

solves the problem.
