Digital Ocean Droplet Magento 2 Extension not recognized after setup:upgrade

Question

I added an extension to a new magento 2 digital ocean droplet. But when I run setup upgrade the extension is not added to app\etc\config.php. I've added a folder in app called tomispepe and added a folder in it called checkout.

these are my files: /var/www/html/magento/app/tomispepe/checkout/registration.php DIR );

the module xml is here: /var/www/html/magento/app/tomispepe/checkout/etc/module.xml

that's it.

Then I ran: ./bin/magento cache:flush ./bin/magento setup:upgrade

then this should have included my new extension cat app/etc/config.php | grep tom but it did not!

in my dev env this works but on my droplet it does not. There must be something unique about my droplet. Please help.

Answer 1

This assumes that you are adding the module via app/code and not as a dependency via composer.

After adding a module under app/code/, assuming it has at minimum a registration.php file and etc/module.xml file that contain the proper statements(I would recommend taking the skeleton for both from a core module), you will need to enable the module by running:

$ bin/magento module:enable <Vendorname_Modulename>

so if your module should live under app/code/tomispepe/checkout/ then the module name would likely be Tomispepe_Checkout.

Then, after enabling the module, the cli utility will typically recommend running any data and install scripts(there may be none for your module, just run this anyways) via:

$ bin/magento setup:upgrade

At that point you can ensure that your module is enabled by running:

$ bin/magento module:status

Ensure that your module is under the "List of enabled modules". As a side note, app/etc/config.php is modified by the bin/magento cli commands and so you should prefer using the commands over reading the contents of that file.
