从 git 存储库安装 ruby​​ gem 失败：rake aborted

Question

我成功克隆了一个 git 存储库到我的本地机器，但我无法安装 gem.. （我安装了 rake 10.1.0），还安装了依赖的 gem oauth

    git clone git://github.com/marcel/twurl.git
    rake gem --trace

错误信息：

使用

gem build twurl.gemspec

而不是

rake gem

错误消息明确指出，Rakefile 没有名为 gem 的任务。

在您构建完gem 之后，使用gem install 安装它。
