一切都在我的本地完美运行。我在服务器上适当地安装了所有东西，当我运行rake db:bootstrapor时rake db:migrate，我得到了这个：

有人想出这个吗？

您不必删除初始化程序文件initializers/whatever.rb，只需测试 spree 实例是否存在：

if Spree::Config.instance
    Spree::Config.set(:stylesheets => 'screen')
end

好的，看起来在我的扩展中我有这个：

Spree::Config.set(:stylesheets => 'screen')

但既然这是设置了两次？不确定..但如果我删除它，一切都会完美运行，因为“屏幕”已经在默认首选项中设置。

然后我必须确保以结尾运行我的迁移：RAILS_ENV='production'

我们是金子！

在关注http://osdir.com/ml/spree-user/2009-11/msg00248.html并设置首选项以在文件中禁用 SSL后，我遇到了同样的错误initializers/prefs.rb。删除它允许我运行我的迁移。

这是在我的开发机器上

我对 rvm 有同样的问题。与确实有效的干净 gemset 进行比较时，问题在于有问题的 gem 既在捆绑包中又在 gems 目录中。因此，一种可能的解决方法是创建一个新的 gemset 并运行 bundle install。

跟着这些步骤：

一：注释掉“config/initializers/spree_config.rb”中的所有内容

二：运行：

bundle exec rake db:migrate

三：取消注释config/initializers/spree_config.rb

四：运行：

bundle exec rake db:bootstrap
