Class 'Composer\InstalledVersions' not found

we are using sentry-laravel package which requires your package.
but after installation we get below error.
Class 'Composer\InstalledVersions' not found
we are using composer.phar instead of installing composer.
You're installing using --ignore-platform-reqs, which skips on checking if a specific requirement of 1.4 is present. That requirement is:
pretty-package-versions/composer.json
Line 7 in 1fd8d3b
composer-runtime-api is a meta-package that requires using Composer 2.0 (currently in alpha); if you check your platform requirements correctly, you won't be able to install 1.4 (and newer) of this package, and you will obtain a compatible version instead (1.3 more likely).
Closing as stale. Feel free to reply or reopen if this is not resolved.
it works fine after upgrading to Composer 2.0+.
Maybe you are using an old version of 1.0+.
'Composer\InstalledVersions' is onl for the Composer 2.0+.
