npm突然出现错误

Question

I normally use npm run watch while editing sass file.
This timenpm run watch was misbehaving like continuously working without stopping, but that time no errors. When I suddenly stopped it, and after few time run it again I am getting this error for no reason. I didn't do anything else after terminating the process just edited the sass file.

As per the error I tried to update my node and npm. Before I was using node version v6.6.0, then I updated it to v6.10.2, but could not find in any change in the error other than the version.

I tried deleting the node_molecules and run npm install again.
tried npm cache clear.

How can I fix this error??

My package.json file looks like this
