Question

When I run $ rspec spec/ I receive this error:

You must use ANSICON 1.31 or later (http://adoxa.110mb.com/ansicon/) to use colour on Windows

I have rspec and rspec-core installed:

bundle show rspec

C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/rspec-2.0.1

bundle show rspec-core

C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/rspec-core-2.0.1

What do I need to do to run rspec?

Answer 1

Well, the solution is right in the error message:

Consider using bundle exec.

So you type:

$ bundle exec rspec spec/

But that’s twice as many characters to type! Can’t have that! So consider bundle install –binstubs:

Do this once:

$ bundle install --binstubs          

Now this “just works”

$ rspec spec/
