Not able to download, conflicts with symfony/yaml

[Prashant Sharma]

I am sharing here my Composer.Json which has symfony/yaml installed as per your requirement shows, but still after it show that
Using version ^2.2 for shipu/themevel
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- shipu/themevel v2.2.2 requires symfony/yaml 5.1.x-dev -> satisfiable by symfony/yaml[5.1.x-dev] but these conflict with your requirements or minimum-stability.
- shipu/themevel v2.2.1 requires symfony/yaml 5.1.x-dev -> satisfiable by symfony/yaml[5.1.x-dev] but these conflict with your requirements or minimum-stability.
- shipu/themevel v2.2 requires symfony/yaml 5.1.x-dev -> satisfiable by symfony/yaml[5.1.x-dev] but these conflict with your requirements or minimum-stability.
- Installation request for shipu/themevel ^2.2 -> satisfiable by shipu/themevel[v2.2, v2.2.1, v2.2.2].

Installation failed, reverting ./composer.json to its original content.
