Composer uninstalls other extensions when i install a plugin

Question

When i run following command:

php composer.phar require kop/yii2-scroll-pager "dev-master"

While installing it removes other extension.

Screenshot:

here is the complete Composer.json file:

{

        "npm-asset-library": "vendor/npm",
        "bower-asset-library": "vendor/bower"
    }
}
}

Can anyone tell me how to install extension/plugin without uninstalling other plugins/extension. Any thoughts!

Answer 1

To avoid uninstallation of other extensions just do following steps.

1) "kop/yii2-scroll-pager": "dev-master"

to the require section of your composer.json file.

2) php composer.phar update

run this command in Cmd.

by Doing this you will get all extensions latest versions as well as yii2-scroll-pager will be downloaded.

Hope this will help you.
