Ruby Installation on Mac OSX fails - please help!

Question

I am extremely frustrated with ruby on Mac OS X. I have tried RVM and regular installations of ruby, and nothing seems to get it to work well. With RVM, rails throws errors at me, and with a regular installation of ruby 1.9.2-p180, somehow my computer reverts back to ruby 1.8.7 over time. Can someone please help? A detailed instruction on how to just reset my ruby installation from a clean slate would be very helpful.

Thanks so much in advance!

Answer 1

I'm using macports for all my needs:

1. go to www.macports.org
2. download installation dmg
3. install it
4. open a new Terminal windows (or source ~/.profile )
5. port selfupdate
6. port search ruby
7. pick what one want (ruby for 1.8.7, or ruby19 for 1.9.2)
8. sudo port install ruby
9. port search rb-
10. pick what want and install

everything will install into /opt - so does not interfere with your standard system binaries.

Note, than everything will compile - and take a long time.

Answer 2

rvm --default use 1.9.2

This has been covered multiple times here. A simple search will find many questions.

See: Installing RVM (Ruby Version Manager)

i installed ruby 1.9.2 with RVM, but when i type "ruby -v" is telling me the ruby vi have is 1.8.7 (mac)
