Searched gems which supports only ruby 2.6
1 like1,033 views
The document appears to be summarizing Ruby gems that have updated their required Ruby version to 2.6 or higher. It loads gem specification data, then loops through each gem checking if the required Ruby version now satisfies 2.6 or higher but not older versions. Any gems meeting that criteria will be printed out. It also handles any errors encountered during the checks.
