I have installed latest version of Megento 2, everything was worked fine. I have created one custom module. After activated my custom module, I got an error like "Setup version for module 'Chilly_Draji' is not specified".

When i enable my module in first time, I didn't write composer.json file. After creating composer.json file, I can't able to upgrade. when i run command "php bin/magento setup:upgrade", got an below error

[InvalidArgumentException]
There are no commands defined in the "setup" namespace.

After removed composer.json file,It's working fine..
when i install new magento 2 module which was created by module creator, I got an error like "Setup version for module 'Chilly_Test' is not specified" every time. Its happening only in apache server. That same module working fine in "Nginx" server

@DRAJI you need to also create a etc/module.xml with setup_version like this. Also, can you be more specific about which module creator you used?

[assaflei]

I had a similar error message when creating a simple hello world module
My problem was in the module.xml file, in which the header line "" was not the first line in the file

FYI

Hi, Thanks for the reply. It was an ownership permission issue. After set ownership permission on specific plugin folder, It worked fine!

Thanks!

Hi, If you have composer.json file, Plz check after remove it.

For ubuntu - chown -R :www-data .

Giving full control (read/write/execute) to var and pub directory solved this issue for me.

sudo chmod -R 777 var pub

You may also try running the command using sudo.

sudo php bin/magento setup:upgrade
