An exception while creating "Magento\Setup\Console\Command\ModuleUninstallCommand"; no instance returned

[milanstojanov]

While trying to install Magento_SampleInterception module (https://github.com/magento/magento2-samples/tree/master/sample-module-interception) with the standard flow:

1. bin/magento module:enable Magento_SampleInterception
2. bin/magento setup:upgrade

I got the following exception:

Autoload error: An abstract factory could not create an instance of magentosetupconsolecommandmoduleuninstallcommand(alias: Magento\Setup\Console\Command\ModuleUninstallCommand).

After digging around for a while, I managed to get a bit more friendlier message:

An exception was raised while creating "Magento\Setup\Console\Command\ModuleUninstallCommand"; no instance returned.

However, it's still not very clear how and why it ended up here.

As a temporary workaround, I manually added:

'Magento_SampleInterception' => 1 to etc/config.php
and a new row in setup_module table: Magento_SampleInterception | 2.0.0 | 2.0.0

This did a trick, but an investigation is clearly needed.

P.S. All sample modules are requiring "magento/framework": "~0.74", which should be updated as well.

Thanks,
Milan

@milanstojanov in the develop branch we have pushed a fix that will give a more detailed error. Can you please try with the develop branch for more details?

Hi,

I pulled the latest code, and it's displaying the exceptions which I already tracked:

Looks like something's wrong with Store composer.json. Could you, please, describe how you originally installed Magento? Is it via cloning the Git repository or fully via Composer?
And just in case, could you please, check file app/code/Magento/Store/composer.json - does it look valid?

[milanstojanov]

Thanks @buskamuza.

I'm running Merchant Beta, and I installed it by cloning Git repository (https://github.com/magento/magento2.git) and then I used Composer to install dependencies.

app/code/Magento/Store/composer.json looks normal and valid (tested):

{
"name": "magento/module-store",
"description": "N/A",
"require": {
"php": "~5.5.0|~5.6.0",
"magento/module-directory": "1.0.0-beta",
"magento/module-ui": "1.0.0-beta",
"magento/module-config": "1.0.0-beta",
"magento/module-media-storage": "1.0.0-beta",
"magento/framework": "1.0.0-beta",
"magento/magento-composer-installer": ""
},
"type": "magento2-module",
"version": "1.0.0-beta",
"license": [
"OSL-3.0",
"AFL-3.0"
],
"extra": {
"map": [
[
"",
"Magento/Store"
]
]
}
}

Can you or someone else try installing any M2 module? Is it just me or it's a confirmed bug? If it's just me, I will try reinstalling Magento.

@milanstojanov if you compare line 6, catalog is missing. Also is * missing on for magento/magento-composer-installer ?

[milanstojanov]

You are right. And that's because I pasted composer.json from another laptop where I didn't previously pull the latest code from develop. However, pulling the code alone didn't solve the issue.

What helped in my case is "composer update". I completely forgot to that when I pulled the code. :)

So I can confirm that everything is working as expected. Thanks everyone for participating in this thread. I will close this issue.

try to downgrade PHP to recommended & compatible version.

"    - magento/product-community-edition 2.3.1 requires php ~7.1.3||~7.2.0 -> your PHP version (7.3.5) does not satisfy that requirement.
"
