Installing RubyGems as non-root user on MacOS X

ruby-talk

I'm trying to install RubyGems on MacOS 10.3.9 in my home directory as a non-root/non-admin user. I have Ruby 1.8.2 installed via DarwinPorts and Ruby 1.8.2 is in my PATH ahead of the system ruby.

I am installing RubyGems 0.8.10 from source (not using DarwinPorts) as follows.

   $ ruby setup.rb config --prefix=/Users/jose/
   $ ruby setup.rb setup
   $ ruby setup.rb install

taken from the RubyGems manual[1]. The first two commands complete without error but the final command fails with the following:

hook /Users/jose/Projects/Ruby/rubygems-0.8.10/./post-install.rb failed:
You don't have write permissions into the /opt/local/lib/ruby/gems/1.8 directory.
Try 'ruby setup.rb --help' for detailed usage.

I've googled a bit for this but so far have not found any fixes. How do I stop rubygems from trying to modify my main ruby setup. I would like Rubygems to be contained entirely within my home directory. Is that possible? Do I need to build my own private copy of Ruby as well?

Many thanks for and advice.

That did the trick. Only downside seems to be that readline support doesn't work in irb but that's not a big problem.

Yeah, I can't get readline support to work in irb on my Mac either. If anyone knows please let us know....

This may not be the best way but I used the following script to build my private copy of ruby _with_ readline support. Looking at the log file in the readline ext directory it seems it wasn't picking up my LDFLAGS settings. The readline library was already installed in /opt/local using DarwinPorts.

-8<- cut here ----
#!/bin/sh

PREFIX=${HOME}/tools
export PREFIX

LDFLAGS="-L${PREFIX}/lib -L/opt/local/lib"
export LDFLAGS
# For readline support
DLDFLAGS=${LDFLAGS}
export DLDFLAGS

CFLAGS="-I${PREFIX}/include -I/opt/local/include"
export CFLAGS

VERSION=1.8.2

cd ruby-${VERSION}
../configure --prefix=${PREFIX}
make
make install
