While creating a custom module if you gave the wrong module name, When you try to run any terminal command you will get an error like

There are no commands defined in the “setup” namespace

Now I understand the solution from one of the answer in this question.But when I try to change the module again, I am always end up in the same error even after I update everything Or I also tried removing other files. If I keep the registration.php it shows error If I delete the registration file, it works. How can I use the same module again.

Remove extension from the magento 2, you need to do following things.

  1. Identify Magento 2 extension name, you can get name from registration.php.

  2. Remove extension entry from app/etc/config.php (entry identify from step1)

  3. Remove extension entry from setup_module table in magento database. (entry identify from step1)

  4. After remove the things, please also run these commands.

    php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento indexer:reindex
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy

  5. Now added all your new file and run command again.

After this you can now used same module name for others.
