Rails 2.3.5 和 oauth 插件

Question

我使用 Rails 2.3.5 从头开始​​启动了一个 Rails 应用程序，并安装了 oauth-plugin。安装是通过运行 script/plugin install git://github.com/pelle/oauth-plugin.git 完成的。

现在，当我尝试启动服务器时，出现以下错误：

我无法弄清楚为什么会失败。我缺少依赖吗？我还可以向其他人提供哪些其他信息来帮助我解决这个问题？

Answer 1

看起来 oauth-plugin.gemspec 适用于 Rails 3. 请注意此行加载 gem 的 0.4.4 版本：

s.add_dependency(%q, [">= 0.4.4"])

首先尝试撤消 script/plugin install 所做的更改。

然后，根据 gem 的 github 页面上的自述文件，我将尝试手动安装 gem：

gem install oauth-plugin --pre

没关系，我在上面得到了版本 0.4.4，这可能又适用于 Rails 3。
尝试：

gem 安装 oauth-plugin -v=0.3.11

然后，添加到environment.rb：

config.gem "oauth"
config.gem "oauth-plugin"
