[ERROR] ng has unexpectedly closed (exit code 127)

When I enter ionic serve, I get this error message

ng.cmd run app:serve --host=localhost --port=8100
[ERROR] ng has unexpectedly closed (exit code 127).

Edit: solved!

One of the folders in the served path contained a “!” character. Served just fine once the folder’s name was changed.
