  Potential causes:
   - A typo in the package name
   - The package is not available in a stable-enough version according to your minimum-stability setting
     see &lt;https://getcomposer.org/doc/04-schema.md#minimum-stability&gt; for more details.
  
  Read &lt;https://getcomposer.org/doc/articles/troubleshooting.md&gt; for further common problems.
  
  Installation failed, reverting ./composer.json to its original content.
