Rails - problem installing Spree

问题

I'm having a problem installing Spree in a Rails app.

when I run gem 'spree' (as per the instructions on http://spreecommerce.com/documentation/getting_started.html)

I get the following error:

ERROR:  While executing gem ... (RuntimeError)
    Unknown command spree

I have the following Spree gems installed:

gem list spree

*** LOCAL GEMS ***

spree (0.30.1)
spree_api (0.30.1)
spree_auth (0.30.1)
spree_core (0.30.1)
spree_dash (0.30.1)
spree_promo (0.30.1)
spree_sample (0.30.1)

when I installed the Spree gem I used:

sudo gem install spree

thanks for any help.

回答1:

The instructions actually say to add gem 'spree' to your Gemfile (and not execute it as a command):

Edit the Gemfile in your Rails application by adding the following:

gem 'spree'
