ERROR in EPERM: operation not permitted, open

Question

I have a React application that starts up fine and has been running for some time now. However, now when I go to make any edits, I am met with the following error:

ERROR in EPERM: operation not permitted, open 'C:\Users\Administrator\Desktop\ApplicantApp\FrontEnd\build\node_modules.cache.eslintcache'

Any ideas how to fix?

Answer 1

My exact error was

"ERROR in [eslint] EPERM: operation not permitted, open 'Y:\Caido\Dev\CaidoWebFramework\caido_nodejs\node_modules.cache.eslintcache'"

and I solved it like this: In Windows, I right clicked for folder properties on the folder Y:\Caido\Dev\CaidoWebFramework\caido_nodejs\node_modules.cache and unchecked ReadOnly and Hidden.

But I don't really understand what heappened because:

• if I reopen the folder properties again the ReadOnly and Hidden boxes are not changed even if I just saved the same dialog with both checkboxes unchecked.
• the message is about a file that can't be opened and I don't know why these atributtes would affect the behaviour.

Still I'm sure that after I uncheckd these checkboxes for the first time the problem dissapeared.
