Problems installing extension from Marketplace

[jbalca]

Hi,

We're running Magento Open Source 2.1.3.

We have not been able to install extensions from Marketplace using composer.

For example we're trying to install Klarna checkout using the following command:

composer require klarna/m2-checkout:3.0.0

And we get this output:

We're having the same problem we other modules. We know the package name is right because we purchased the module in marketplace and checked that information:

We have specified

https://repo.magento.com/ as one of our repositories in our composer.json file.

Can anyone give us a tip of what might be the problem?

Thank you.

Magento 2.1.3 is not supported (you can run 2.1.2 or 2.1.4 and higher, just not 2.1.3) because it was a very buggy release. Please try upgrading to a newer release of Magento and you should be able to install the module then.

Hello @jbalca

please create one auth.json into your root folder add below code there

{
   "http-basic": {
      "repo.magento.com": {
         "username": "<public-key>", // get from magento (make sure you purchase from same account)
         "password": "<private-key>" // 
      }
   }
}

Then run 

composer require klarna/m2-checkout

Hello,

there are still some issues installing extensions via composer from marketplace.

I bought, for example, Klarna payments and hit:

composer require klarna/m2-payments:5.0.1

I got:

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for klarna/m2-payments 5.0.1 -> satisfiable by klarna/m2-payments[5.0.1].
    - klarna/m2-payments 5.0.1 requires klarna/module-core 4.2.2 -> no matching package found.

I am sure I got correct public and private keys filled in auth.json file.

The question is, how come no matching package occurs as it should not!

Hey @gelanivishal thanks for your reply!

The issue in this case is github repository we use (https://github.com/magento/magento2) and Magento project structure I use.

If you clone tag 2.2.x from above repo, you will see that there is no klarna as well as many others module too. However, when you download ZIP package of Magento (https://magento.com/tech-resources/download) you will get all the modules you need and of course Klarna.

I got suspicion that building process of Magento2 github repository has some issues or bugs and that is why you cannot see some of the packages there. I don't want to believe that Magento communty didn't put these modules in repository in purpose.

Anyway, thanks for reply. You got kudos :-)
