You just pasted your whole error log. I don't have any idea what you did and how this error was thrown. Anyway with some hunch I'm guessing you updated your node version after you did npm install on your project. The error is likely caused by node-sass which totally depends on the version of node.

So, I suggest you to first try this command npm rebuild node-sass . And if this won't help then remove node_modules/ and do npm install again.
