Error installing Ruby in Yosemite

Question

I have recently updated my OS X to 10.10 and since then facing issue installing ruby through RVM. There is a dependency on gcc46 which I am unable to resolve. Any help is appreciated. Below is the error stack.

rvm reinstall ruby-1.9.3-p547
ruby-1.9.3-p547 - #removing src/ruby-1.9.3-p547 - please wait
ruby-1.9.3-p547 - #removing rubies/ruby-1.9.3-p547 - please wait
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-1.9.3-p547.

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

EDIT :

I was able to install using below command.

rvm install 1.9.3 --with-gcc=clang

Could someone help me understand what's the difference with the above command? Thanks

Answer 1

Always try to use the latest version whenever possible, or else check the correct versions of each component which is compatible with the version of the component you are installing.

If you follow this guide it will be much easier.

I am completely new to ruby, but it worked fine for me by using this.

Answer 2

Thanks @JanStrnádek for the answer. I solved all the dependencies from left to right and installed gcc using the below command and tried installing ruby again. It worked.

brew install homebrew/versions/gcc48
