RVM Does Not Install Ruby 1.9.2 on Snow Leopard: 'Error running 'make '

Question

When I try to install Ruby 1.9.2 on Snow Leopard using:

rvm install 1.9.2

I get the following:

ERROR: Error running \'make          


        

Answer 1

Compile and install your own readline:

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
cd ..

Remove the ruby: rvm remove 1.9.2

Install it again: rvm install 1.9.2

(You might need to add source it if local path is not in your directory: rvm install 1.9.1 -C --with-readline-dir=/usr/local/

That should do it.

------------- EDIT --------------

As noted in the comment below, if you use homebrew, then you should brew install readline. And if you're using a Mac, you should be using homebrew.

------------ HOW TO COMPILE READLINE ON 10.7 ---------

"readline-6.2 has not been updated for Mac OS X 10.7 (darwin11), so open the support/shobj-conf and change darwin10 to darwin11 in the two places where it appears."
