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!

The screenshot makes it difficult to read what is happening. Can you post a gist of your `composer.json`, `composer.lock`, and the command output with the `-vvv` flag? — Steve Buzonas, Jun 09 '16 at 01:03

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.

Your screenshot shows an error message:

Content-Length mismatch
http://packagist.org could not be fully loaded, package information was loaded from the local cache...

This means Composer has no complete information about all packages, and anything might happen then.

Make sure you have a working online connection, and try again.
