How do I downgrade Composer?

Question

How can I downgrade composer 2? 

Answer

1. Download the older RPM from the httpupdate server: 

   wget http://httpupdate.cpanel.net/RPM/11.86/centos/7/x86_64/cpanel-php-composer-1.8.6-1.cp1186.noarch.rpm

2. Remove composer 2:

   rpm -e cpanel-php-composer-2.0.6-1.cp1186.noarch

3. Install the downloaded older 1.8.6 RPM:

   rpm -ivh cpanel-php-composer-1.8.6-1.cp1186.noarch.rpm

4. Verify the package was installed correctly:

   rpm -ql cpanel-php-composer-1.8.6-1.cp1186.noarch

5. Set the target to uninstalled:

   /usr/local/cpanel/scripts/update_local_rpm_versions --edit target_settings.composer unmanaged

6. Verify the installed composer version:

   /opt/cpanel/composer/bin/composer -V

Completing the above steps will downgrade Composer and prevent cPanel from updating the Composer version.

Please note, that only the following versions of Composer are available in the repository.

• 1.8.6
• 2.0.6
