Heads up for possible "Permission denied" error

[hiulit]

Hi there!

I followed your tutorial (thanks btw!) and I found myself getting this error:

$ gem install sass
Fetching: sass-3.4.23.gem (100%)
Successfully installed sass-3.4.23
1 gem installed

$ test/travis.rb
/home/travis/.travis/job_stages: line 53: test/travis.rb: Permission denied

So I added a new line to .travis.yml to fix permissions:

before_install:
 - gem install sass
 - chmod +x test/travis.rb

And I got rid of the error! :)

I read that this could also be done like this:

before_script: 
 - chmod +x test/travis.rb

But I haven't tried that solution.

I just though that it would be useful to add it to your script to avoid possible errors.
That's all!

Related to #7, I've been getting this error:

$ gem install sass
Fetching: ffi-1.9.18.gem (100%)
Building native extensions.  This could take a while...
Successfully installed ffi-1.9.18

ERROR:  Error installing sass:
	sass requires Ruby version >= 2.0.0.
The command "gem install sass" failed and exited with 1 during .

So I added

rvm:
  - 2.4.1

to .travis.yml to get the latest Ruby version.
