json gem install error on bundle install

Question

When I try to do a bundle install I get the following json error. The bundle install does not complete. What gives?

Errno::EACCES: Permission denied - /usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/json-1.7.5/.gitignore
An error occurred while installing json (1.7.5), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.5'` succeeds before bundling.

>>$ gem install json -v '1.7.5'
ERROR:  While executing gem ... (Errno::EACCES)
Permission denied - /usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/json-1.7.5/.gitignore

EDIT: The sudo install command gives the following error:

>>$ sudo gem install json -v '1.7.5'

ERROR:  Error installing json:

Answer 1

you need to install ruby1.8-dev and not just ruby1.8, you are missing the development headers.

if on OSX:

sudo install ruby1.8-dev

if on unix

sudo aptitude install ruby1.8-dev

or

sudo apt-get install ruby1.8-dev

go into your directory with rubygems source and run: sudo ruby setup.rb after that run:

if on OSX:

sudo gem install json -v '1.7.5'

some unix system may need gem version command to work properly so you should run:

sudo gem1.8 install json -v '1.7.5'
