php - How to fix Composer error: "could not scan for classes inside dir"?

Question

I'm trying to install composer in terminal by entering this command:

php composer.phar install

it starts to install required packages but I'm getting this error type:

[RuntimeException]
Could not scan for classes inside "app/commands" which does not appear to be a file nor a folder

How can I overcome this issue?

Answer 1

Usually this happens when you have some corrupted files or any composer update has crashed or interrupted.

To solve, just delete the vendor folders and run composer install
