Instance Method Details

#depends_on(gem_name) ⇒ Boolean

This method requires and loads the given gem, and then checks to see if the version of the gem meets the requirements listed in ‘langchain.gemspec` This solution was built to avoid auto-loading every single gem in the Gemfile when the developer will mostly likely be only using a few of them.

Parameters:

  • gem_name (String) —

    The name of the gem to load

Returns:

  • (Boolean) —

    Whether or not the gem was loaded successfully

Raises:

  • (LoadError) —

    If the gem is not installed

  • (VersionError) —

    If the gem is installed, but the version does not meet the requirements
