Error

I write create-react-app myapp, after all installations I write npm start, and an error appears. Why?

{Failed to compile.

try removing “!” in the folder name… i usually do the same - put "!’ so that it would be sorted to the top, in this case webpack has reservation for that symbol …

I don’t think there’s much we can do about this one. Just avoid directory names that start with !.
