Rails - Amazon minitest/unit (LoadError)

Question

我在 Amazon EC2 上托管了一个 Ruby on Rails 应用程序。我正在使用 Java SSH 客户端连接实例。当我转到我在亚马逊上的工作目录并尝试输入 rails c 时，它显示错误 require': cannot load such file -- minitest/unit (LoadError)。我不知道为什么我无法访问 rails 控制台。

我试图通过安装gem install minitest-rails 来解决这个错误，但它抛出了错误

ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/share/ruby/1.9/gems/1.9.1 directory.

我尝试在我的 gemfile 中添加两个 gem gem 'turn' , '< 0.8.3' 和 gem 'minitest-rails 然后推送到 AWS 但没有得到任何东西。

如何摆脱这个错误。我想访问我的 rails 控制台。请帮忙。提前致谢。

Answer 1

为了克服这个错误，我必须同时执行“gem install minitest”并将“gem 'minitest'”添加到项目 Gemfile。我通过阅读this open issue for Rails on GitHub 上的 cmets 得到了这个解决方案；在解决此问题之前，您可能会在那里找到进一步的解决方案。

Answer 2

试试这个

group :test do
  gem 'turn', '< 0.8.3',
  gem 'minitest', '~> 5.0.5'
end

如果我错了，请纠正我，但我猜你正在尝试安装 Cucumber。如果不是，请指定您的 rails 版本和 ruby​​ 版本。
