Error installing ruby 1.9.3

Question

I\'m trying to install Ruby 1.9.3 using rvm. However, when I type:

rvm install 1.9.3

I get the following error:

ERROR: Erro         


        

Answer 1

The simpler, more general solution is to explicitly install the offending package and then reinstall with that package. In my case, it was aborting on openssl_missing, so:

rvm pkg install openssl
rvm install 1.9.3 -C "--with-openssl-dir=$HOME/.rvm/usr"

For your case, it's probably:

rvm pkg install readline
rvm install 1.9.3 -C "--with-readline-dir=$HOME/.rvm/usr"

This of course assumes that you installed rvm as yourself. Change accordingly...

I have been running into issues on 1.9.3 on Snow Leopard, too. My make.log looks like this:

Answer 3

This is an issue with readline. Try compiling readline yourself from source:

curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.1.tar.gz
tar xzvf readline-6.1.tar.gz
cd readline-6.1
./configure --prefix=/usr/local
make
sudo make install

Answer 4

Which version of Xcode are you using - 4.1 or 4.2? There are some issues with 4.2 and Ruby because 4.2 uses LLVM instead of GCC as the main compiler. Some of the information here may help you if you have 4.2. If you have 4.2 but don't mind going back to 4.1 it's possible to download 4.1 from Apple still on their developer's page but it's rather buried.
