Ruby 安装RHC包Ubuntu

我刚刚在我的笔记本电脑上安装了初级操作系统，它有

apt-get

软件包管理系统，比如Ubuntu

我需要在笔记本电脑上安装

RHC

客户端工具，但是当我运行

sudo apt get install rhc

我得到一个错误：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package rhc

在联机搜索时，有些人建议我运行以下命令：

cat /etc/apt/sources.list

我做到了，并获得了以下详细信息：

知道我为什么不能安装这个基本软件吗？

TL；DR。尝试将其作为一个组件安装

有一个用于trusty的Ubuntu 14.04 LTS版本，基本操作系统就是基于该版本构建的

rhc

软件包仅适用于wily、xenial或yakkety版本的Ubuntu（请参见本手册右上角）

OpenShift错误地声明，从Ubuntu vivid发行版开始，

rhc

可用，但单击该链接会导致一个不存在的页面；DR。尝试将其作为一个组件安装

我尝试了

sudo apt get install gem

，它说

gem已经是最新版本了。然而，当我尝试
gem安装rhc
时，它说
程序“gem”可以在以下软件包中找到：*ruby*rubygems
Hi-Greg，这可能是因为您正在通过
sudo
使用超级用户（aka
root
）安装
gem
程序，在当前用户下执行
gem
命令时。要快速解决此问题，请尝试运行
sudo gem install rhc
。不过，我建议您通过
rbenv
或
rvm
安装ruby，这样就可以在不需要超级用户的情况下安装/操作gems。然后，我得到错误
sudo:gem:command not found
。这很奇怪。感谢btwI提供的帮助，btwI尝试了
