Question

首先要提前感谢：）

当我尝试在rails应用程序中安装gem时，它会显示如下所示的错误。

 $ rake gems:install
Invalid gemspec in [/home/aspireedge/.rvm/gems/ruby-1.8.7-p374/specifications/carmen-1.0.0.beta2.gemspec]: Illformed requirement ["#<YAML::Syck::DefaultKey:0x7f630b62a000> 2.6.1"]

当我尝试更新gem

    $ gem update --system

Latest version currently installed. Aborting.

我也尝试用rvm gemset empty

删除gem

但仍然有错误

尝试升级您的RubyGems并删除并再次安装carmen gem：

gem update --system
gem uninstall carmen
gem install carmen

为Ubuntu 14.04 +提供了最新版本的Ruby 2.x的PPA：

$ sudo apt-get remove rubygems
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.4

$ ruby -v
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux-gnu]

无法在Rails 2.3.8＆amp ;;中安装宝石Ruby 1.8.7？
