My first attempt to build Yandex Mobile Ads Example for iOS

Posted by | iOS | Tagged |

According to the official repository docs I tried to install CocaPods:

 sudo gem install cocoapods

but got the following error:

ERROR:  Error installing cocoapods:
        The last version of drb (>= 0) to support your Ruby & RubyGems was 2.0.6. Try installing it with `gem install drb -v 2.0.6` and then running the current command again
        drb requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.

Installed some dependencies and the installation of CocoaPods succeeded:

sudo gem install drb -v 2.0.6
sudo gem install activesupport -v 6.1.7.8
sudo gem install cocoapods
