Cannot compile namespaces when the ‘–isolatedModules’ flag is provided

I faced similar issue in react + ts. I had commented out all my code.

Turns out
A global file cannot be compiled using ‘–isolatedModules’. Ensure your file contains imports, exports, or an ‘export {}’ statement.

So, added something like:

export const foo = 'foo';

or

export {}

It’s a temporary solution, else you can delete the file with commented code or update tsconfig.json
