Spree 设置错误：设计 Github Gem 'spree_auth_devise' & Rails Server

Question

我是 Rails 新手，想试用 Spree Commerce，但在尝试安装 Spree 时遇到了一些问题，我一直在关注 Spree installation guide 。

当我尝试安装 Spree 时，出现以下错误：

C:\Users\Ross\Documents\eCommerce\Spree\test_spree_store>spree install

Would you like to install the default authentication system? (yes/no) [yes] y

←[31mYou passed :github as an option for gem 'spree_auth_devise', but it is invalid.←[0m

以下是我的应用程序 Gem 文件：

source 'https://rubygems.org'

gem 'rails', '3.2.9'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password

gem 'spree_usa_epay'
gem 'spree_skrill'
gem 'spree_auth_devise', :github => 'spree/spree_auth_devise', :branch => '1-2-stable'

我尝试在不接受默认身份验证设置的情况下再次运行 spree install（注意，我首先从我的 gem 文件中删除了最后四行代码）。

即使耙子被中止，它似乎也能工作？但是，当我尝试运行服务器时，它不起作用并且出现以下错误：

我不知道从哪里开始处理所有这些错误，并且害怕弄乱这些文件，而且 rails 服务器在其他 rails 应用程序中也能正常工作（非狂欢），任何帮助将不胜感激。

谢谢， 罗斯

作为一个在 Windows 上使用 Rails 有相当多经验的 Windows 用户，我会敦促您省去很多麻烦，并使用 VirtualBox 或 VMware 设置一个 Ubuntu 12.04 LTS vm。 Vagrant 可以让你更加自动化。

也就是说，我会确保您满足系统级别的先决条件。

如果您不在 Ruby 1.9.3-p327 上，请升级到它。这不太可能是问题，但它包含一些重要的安全修复程序。

通过运行 gem update --system 确保 ruby​​gems 是最新的。

确保 bundler 和 rake 是最新的：gem update bundler 和 gem update rake。如果您不是今天才安装它，那么您也可以在使用它的同时执行 spree gem。

既然您是最新的，就从一个新项目开始：

rails _3.2.9_ new spree_project [-d mysql if you're using mysql]
cd spree_project
spree install

每当您在项目中运行任何 rake 或 rails 命令时，您也必须在它们前面加上 bundle exec，否则可能会加载错误的 gem，这会给您带来莫名其妙的头痛。所以运行测试服务器的正确命令是bundle exec rails s。

看看这对你有什么作用。
