I just downloaded ruby 2.6.5 and as well as sqlite3. I followed the tutorial to install rails and typed "gem install rails" in the command prompt but ran into this error. I have no idea what these things are and have been stuck here for quite a long time. Could someone give me some advice on this please? Any help will be greatly appreciated!

Please help me to get rid of this error.
have you followed any Youtube tutorials if yes, then yeah you are not alone I have also screwed up and don't have any solutions yet but I think reinstalling from the beginning from your own not from the tutorials, you may succeed.
If I succeed then I would tell ya!
I have recently tried to install rails via gem by running gem install rails. However, it always fails with the following error message.

Does anyone know what is actually happening here? I would appreciate any answer. Thanks
Usually, this "multiple target patterns" error when compile gem extensions is caused by spaces in directory names where you have installed your Ruby or your gems.
Especially on Windows, you should install your Ruby to a directory which contains no spaces, rather than your current location D:/Program Files/Ruby30-x64. To fix this, I recommend to uninstall Ruby and install it again to a more appropriate location.
I'm installing Rails on Windows. When I run gem install rails I received message

I have no idea about that error. How to resolve that?
Old question, but might be still be relevant for people arriving through search. I installed the latest Ruby + devkit from https://rubyinstaller.org/downloads/, and it worked (Windows 10)
I have gone through a lot of answers on a similar questions but I have not been successful. I am trying to install therubyracer 0.12.3 on my MAC OSX 10.12.4 and I am receiving the following error. Please help. Been stuck with this for two days now.

I feel this might be the root cause -
