Answer 1

Not sure about the exact meaning of this error, but my fix for this is to delete the directory node_modulesand reinstall the necessary modules with npm install.

The above solution for this error appears in a node project that uses locally installed modules. If there are any global modules that throw this error, you may need to reinstall them.

Answer 2

, package.json.
