Question

I’m having extensive problems getting rvm to work again under OSX Lion. Unsurprisingly, it seems to be a problem with readline, which is noted in several places.

HOWEVER, (and this is an update) it seems that readline itself is not being installed correctly!

Here is what I’ve tried so far:

Reinstalling xcode (4.1) (I also removed the Developer folder first.)

Cleaning and reinstalling all my ports as per http://trac.macports.org/wiki/Migration

Reinstalling readline as per: https://rvm.beginrescueend.com/packages/readline/

Using that specific readline version:

rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

I have also reinstalled rvm entirely. Still no go. Here is the current error I’m seeing:

ERROR: Error running 'make ', please read /Users/tristankromer/.rvm/log/ruby-1.9.2-p290/make.log
ERROR: There has been an error while running make. Halting the installation.

…and the accompanying log file.

So after much investigation, I tried to manually install readline: (from: RVM Does Not Install Ruby 1.9.2 on Snow Leopard: 'Error running 'make ')

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 ..

I get as far as make when I get an error compiling readline:

So it seems like even installing readline I have a problem due to readline.

I then followed The directions from Andy (below) by adding to .bash_profile:

export ARCHFLAGS="-arch x86_64"

and ran:

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

And now I seem to have a different error:

make[1]: Entering directory `/Users/tristankromer/.rvm/src/ruby-1.9.2-p290/ext/tk'

Answer 1

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
