Problem Installing Ruby 1.9.2 on MAC Os Lion

Make error installing Ruby 1.9.2 with RVM and Readline under OSX Lion

I had a very similar issue. I eventually found that adding this to my .bash_profile stopped my initial make errors:

export ARCHFLAGS="-arch x86_64"

Also from the command line run the following:

brew install readline
brew link readline
brew install libxml2
brew link libxml2

Then when you install ruby use this command:

rvm install 1.9.2 -C --with-readline-dir=/usr/local/Cellar/readline/6.2.1/ --with-libxml2-dir=/usr/local/Cellar/xml2/2.7.8

Hope that helps

Installing Ruby 1.9.2 with RVM fails on OS X Lion

When upgrading from 10.5 to 10.6 I had to nuke out all my installed source-built libraries and start over to fully resolve the 32-bit to 64-bit conversion issues. You may find you need to force-rebuild all of your brew packages.

Under MacPorts you just remove the /opt directory, salvaging any database files that might be in there first, and re-install everything again. I'm sure there's a similar procedure for Brew.

There's a way to alter the library load path, too, to set priority, but MacPorts does seem to handle this for you. otool can help diagnose which libraries are being loaded:

otool -L `which ruby`

Make error installing Ruby 1.9.2 via rvm OSX Lion 10.7.2 XCode 4.2

This error has been fixed in 1.9.2-head ... so just

rvm install 1.9.2-head && rvm use 1.9.2-head --default

I'm finding 1.9.3 isn't compatible with a lot of the libraries I use yet. This works with Xcode 4.2.

help installing Ruby 1.9.2 on Lion GM

Mac OS X Lion is not yet released. I've read reports of several bugs in Lion GM (among which even as severe as kernel panics), this is probably also a Lion (or Xcode 4.2) bug, and if not, it's a Ruby bug. RVM is certainly not the cause, as your output indicates the compiled Ruby is crashing.

I would recommend that you wait until Lion is released.

Edit: Now that Lion and Xcode 4.1 is released, I see the issue has been fixed.

Trouble Installing Ruby 1.9.2 with RVM Mac OS X

I don't know if you're still on it, but i succeeded just by doing this ::

sudo rm /usr/local/lib/libz.*

Probably some software has installed a wrong lib... Well wrong architecture

problem with installing ruby 1.9.2 on OS X 10.6.8

I am writing an answer to my own question for anyone with the same problem that I've suffered!

The problem was with "rvm"!

I updated rvm instead of removing it (in some cases, it would be a good idea to completely remove rvm from your system, and re-install it). I followed rvm instructions: http://beginrescueend.com/rvm/install After updating rvm, I was able to install Ruby 1.9.2(!!), and the problem with
"rake" command was gone!!!

I should have suspected rvm sooner, then I wouldn't have wasted one week!

PS Try avoid using sudo when it is not necessary when installing. Someone mentioned that he/she used "sudo" to install when he/she didn't have to, and it just created the same problem as I was having!
