Unable to install Jekyll on Mac OSX 10.9.1 with xcode and rvm installed

Question

Not having any luck installing Jekyll on Mac OSX 10.9.1

I have rvm installed and also Xcode 5.0.2.

When I run gem install jekyll it tells me...

Permission denied - /Users/Vivid/.rvm/gems/ruby-1.9.2-p320/extensions/x86_64-darwin-12

I then ran sudo gem install jekyll and I then get:

ERROR:  Error installing jekyll:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/Vivid/.rvm/rubies/ruby-1.9.2-p320/lib/ruby/gems/1.9.1/gems/fast-stemmer-1.0.2 for inspection.

This is the contents of /Users/Vivid/.rvm/gems/ruby-1.9.3-p327/gems/fast-stemmer-1.0.2/ext/gem_make.out:

Something is clearly not right. Any advice would be magic, cheers.

Answer 1

You need to install gcc-4.2. Make sure you have Homebrew installed and run

brew install apple-gcc42

Make sure you see happy output when you run:

which gcc-4.2

Then try re-running:

sudo gem install jekyll

Boom! Installed.
