[Ruby + Selenium] Fail to install selenium

[ra cras]

Hi,

I'm trying install the selenium with the fallowing command:

gem install selenium-webdriver

But, appears this error: 

Building native extensions.  This could take a while...

ERROR:  Error installing selenium-webdriver:

ERROR: Failed to build gem native extension.

        /usr/bin/ruby1.9.1 extconf.rb

from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

Gem files will remain installed in /var/lib/gems/1.9.1/gems/ffi-1.9.3 for inspection.

Results logged to /var/lib/gems/1.9.1/gems/ffi-1.9.3/ext/ffi_c/gem_make.out

Why?

I had the same issue when I was trying to install selenium-webdriver on my Ubuntu 14.04.

Try following, it should work.

Step 1: sudo apt-get install ruby-all-dev

Step 2: sudo gem install selenium-webdriver

All the best
