how to downgrade symfony2 bundles knp_compnent?

I am new and facing issue with "Manual counting" which is not working in KnpPaginatorBundle and I got solution that I have to downgrade my bundle but I even do not know how to downgrade knplabs/knp-components or knplabs/knp-paginator-bundle. Some one please help me?

Solution

You didn't tell us which version currently do you have or to which version you would like to downgrade for that matter.

However, follow these simple steps:

Go to Packagist's knp-components page
Find the exact version you would like to downgrade to
Put that version tag into your composer.json
Run php composer.phar update "knplabs/knp-components"

Alternatively, you could remove knp-componets altogether and install it again but that is kinda unnecessary.

EDIT:

Based on your comment I see what seems to be a problem you're experiencing. I can think of two ways to resolve this:

Download .tar of current knp-components and downgraded knp-paginator and put them in your src. Remove knp-paginator from your composer dependency list and update vendors. I advice against this.
Fork the knplabs/knp-paginator project to your own and edit their composer.json file by specifying desired knplabs/knp-componets version. Then insert your fork into your composer.json and update vendors. This is by all means preferable way of doing it.

Hope this helps.

EDIT2:

Referencing your fork via VCS:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/modernmonkslab/KnpPaginatorBundle1"
        }
    ],
    "require": {
        "knplabs/knp-paginator-bundle": "dev-master"
    }
}

This should work, given that your fork is public.
