Cannot install plugin

[slavdok]

After running fastlane add_plugin match_keystore, I verified that it added gem 'fastlane-plugin-match_keystore' to the Pluginfile and fastlane-plugin-match_keystore (0.2.1) to Gemfile.lock

However when I try to use it on command line with fastlane match_keystore there is an error:

Error loading plugin 'fastlane-plugin-match_keystore': cannot load such file -- pry
Did you mean?  pty
[!] Could not find 'match_keystore'. Available lanes: <blah blah blah>

Running fastlane action match_keystore gives:

Error loading plugin 'fastlane-plugin-match_keystore': cannot load such file -- pry
Did you mean?  pty
Loading documentation for match_keystore:
Couldn't find action for the given filter.
==========================================

Actually trying to use match_keystore inside a lane produces:

Plugin 'match_keystore' was not properly loaded, make sure to follow the plugin docs for troubleshooting: https://docs.fastlane.tools/plugins/plugins-troubleshooting/
