PhantomJS version 1.4.0 version issue

Question

I installed PhantomJS today and got this error trying to use it:

PhantomJS version 1.4.0
is too old. You must use at least version 1.7.0  
(Capybara::Poltergeist::PhantomJSTooOld)

How can I install the newer version?

I can get the newer version (1.7) at: http://phantomjs.org/download.html

Once I've downloaded it though how do I actually install it?

Answer 1

Are you using Linux or OS X? You'll need to either build from source or install an updated PhantomJS package. You can also download the binaries and install over the system installed PhantomJS. Type "which phantomjs" and it should show the location of PhantomJS.

Answer 2

If you're using homebrew, just:

brew upgrade phantomjs
