无法安装Shoes :ruby

Question

我是ruby的初学者，想要安装和GUI工具包。所以我在网上冲浪，发现shoes是一个工具包，所以我下载了".install“文件，它不能工作，上面写着一些权限错误，然后我下载了旧版本，它是".run”格式的，也不能工作，所以当我尝试下载时，我发现了鞋子的宝石，我得到了下面的ruby版本。我从git上下载了这双鞋，但还是遇到了一些错误。

root@Drona:/home/naren/shoes4# gem install bundler && bundle install

上面是终端输出。安装的Ruby版本为：

ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

有人帮助我们解决这个安装，如果我做了任何错误的鞋安装，然后让我知道

Answer 1

从您的终端目录看，您似乎正在尝试在Ruby1.9.3上安装shoes4。要安装shoes4，您需要JRuby和JDK -请按照in the readme的说明进行操作

由于它的构建方式，Shoes 3不能通过gem install安装。对于Shoes 3，你需要安装脚本，我推荐合适的Shoes 3.2版本from this page。如果此操作失败并出现错误，请让我们知道错误，以便我们提供帮助:)

Answer 2

你应该使用gem程序来安装鞋子。如果在命令行中输入gem install shoes，就应该没问题。

要在应用程序中使用它，您需要创建一个Gemfile并在文件夹中运行Bundle install
