在我的 Heroku/Sinatra 应用程序中，我使用 Ruby 1.8.7 设置了我的 gemfile，然后使用 RVM 将我的默认设置为 2.0.0。现在，当我尝试安装任何新的 gem，例如 Sinatra-flash 或 Pony 时，当我在 main.rb 文件中需要它们时，无法识别或找到这些 gem。

当我在 gemfile 中添加 gem "pony" 时，我收到一条弹出消息：

Gem 'pony' is not available in SDK 'ruby-1.8.7-p385'

即使我已经安装了它。当我gem list在终端中输入时，它会返回我已安装但未被识别为已安装在我的程序中的所有 gem。

如果我在 main.rb 中添加require 'sinatra/flash'或require 'pony'，我会收到一条消息：

no such file to load

我真的很感激这方面的任何帮助，这让我发疯了。

编辑：

使用命令sudo gem install 'gemname'

当我进入时，rvm info我回来了

编辑：在我输入 'rvm use ruby​​-2.0.0' 然后输入 'bundle install'

我明白了；

Could not find gem 'sinatra/flash (>= 0) ruby' in the gems available on this machine.

从 gem "sinatra/flash" 更改为 gem "sinatra-flash" 然后运行 ​​bundle install

通过使用sudo gem install pony，您将触发与 RVM 版本不同的系统 Ruby 安装。不要使用sudo. 只需确保已加载 RVM，然后使用正确版本的 ruby​​：

rvm use ruby-2.0.0

然后运行捆绑器：

bundle install

这应该为您提供完整的环境。
