Module works when in app/code but not when in vendor folder

Question

Seem to have quite an odd issue. I've got a custom module that essentially is just a class which extends a Template.

When I install it using composer; it installs the module into the vendor folder. However, when trying to render a block using the class of the custom module - it won't work if the file is in the vendor folder. If I copy the module files into the app/code folder then it runs perfectly.

Any help would be greatly appreciated.

It is just odd because as soon as I drag the file from the vendor folder which is where composer automatically loads the module into

vendor/[Vendor-Name][Module-Name]/Block/Home/View/Home.php

to the app/code folder - it then works perfectly.

app/code/[Vendor-Name][Module-Name]/Block/Home/View/Home.php

Error:

Class [Vendor-Name][Module-Name]\Block\Home\View\Home does not exist

I also occasionally get this error:

2 exception(s): Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid block type: Wholesome\Display\Block\Home\View\Home Exception #1 (ReflectionException): Class Wholesome\Display\Block\Home\View\Home does not exist

• Prince Patel: Please share composer.json and registration.php in question.
• macho: I followed this post as i had similar problem. Now module is installed in app/code folder, but when i want to run sudo php bin/magento setup:upgrade i get error Autoload error: Module 'VENDOR_MODULENAME' from '/var/www/html/magento2/sites/magento2_test3/app/code/VENDOR/MODULENAME' has been already defined in '/var/www/html/magento2/sites/magento2_test3/vendor/VENDOR/MODULENAME' any idea how to solve this ? thanks

Answer 1

It ended up being the composer.json file which in the autoload section was missing the psr-4 element.

"autoload": {
 "files": [
 "registration.php"
 ],
 "psr-4": {
 "[Vendor-Name]\\[Module-Name]\\": ""
 }
}

Answer 2

Perhaps when you dragged the module, you should remove it from the setup_module and make bin/magento s:d:c and bin/magento setup:upgrade and bin/magento c:c.

and specify the correct namespace and use. I do not see namespace.

I hope that my answer will bring you closer to the solution.

• Jerryl15: Apologies - I accidentally got rid of the namespace when copy and pasting from the IDE to StackExchange - that shouldn't be the issue. I am not sure what you mean by dragged the module. Ideally I don't have to do any dragging as composer update should load the module into the vendor folder. Thanks

@macho can you confirm whether your compose.json / composer.lock file contains the detials about the module which you installed on app/code folder? If so, can you remove that and try again.
