编辑:调试让我更进一步。问题得到澄清。

我们已经安装了 Ruby、RubyGems 和 Rails,并分叉了 shopify_app 项目。我们创建了一个新的 rails 应用程序并在 Gemfile 中添加了三个项目execjstherubyracershopify_app.

运行rails s以启动我们的 rails 应用程序会返回此跟踪:

root@ubuntu:/usr/local/pete-shopify/cart# rails s

自从从 Github 分叉后,我没有修改任何文件。login_protection.rb 的第 1 - 6 行如下:

module ShopifyApp::LoginProtection
    extend ActiveSupport::Concern

    included do
        rescue from ActiveResource::UnauthorizedAccess, with: :close_session
    end

我对此进行了调查,似乎该错误是由 Ruby 1.8 和 1.9 之间的新型哈希语法引起的;key : value而不是key => value.

ruby -v从命令行运行返回ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]. 这似乎没问题......但我做了一些调试,并在文件内部/var/lib/gems/1.8/gems/shopify_app-4.1.0/lib/shopify_app.rb(在顶部)放置:

将 RUBY_VERSION 退出

它打印了1.8.7。**为什么ruby -vRUBY_VERSION给我不同的结果?我是否正确假设这是我的问题的原因?

注意:要升级 Ruby,我安装了更高版本,apt-get然后通过使用update-alternatives --config ruby并选择选项 2 切换到它,如下所示:

root@ubuntu:/usr/local/pete-shopify/cart# update-alternatives --config ruby
There are 2 choices for the alternative ruby (providing /usr/bin/ruby).

  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /usr/bin/ruby1.8     50        auto mode
  1            /usr/bin/ruby1.8     50        manual mode
* 2            /usr/bin/ruby1.9.1   10        manual mode

另请注意:我们是 PHP/Python 开发人员,所以这对我们来说是全新的!

概括:

1 - 我确定语法错误的原因是否正确?

2 - 为什么RUBY_VERSIONruby -v给我不同的结果?

可能与您的权限有关。尝试使用rbenv安装 ruby​​ 1.9.3 。它会将所有内容安装在您的用户目录中,因此您不必担心任何权限问题。
