for 5 hours now I am trying to install a gem that allows me to create an excel file (like this one: https://rubygems.org/gems/excel_rails) in RubyMine and for my life I can't figure out how to do it.
I tried to just type "install gem 'excel_rails'" and "install gem excel_rails" in my RubyMine project file but that did not have the desired result either.
I have the Bundler Gem/Tool and I tried to click "Install" and then it asks me for arguments... but I don't know what to put there and all commands I can think of (e.g. as mentioned above) did not work either.
If I try to implement the gem in my projects without installing it, RubyMine thankfully detects that the actual Gem is missing and trys to help with giving me the option "install", which again opens the Bundler asking me for an argument.
I confess (and you might have noticed), I am fairly new to Ruby and RubyMine. I have been searching for tutorials etc. for my problam, but either they don't work or they are described in ways that I don't understand...
After 5 hours I am giving up on trying to solve it on my own. Can someone help me?
Thanks so much in advance
