Rails -v给我的错误和唯一的解决方案，我发现给出了不同的错误

Question

我试图起床和运行下面的教程，但我曾尝试使用哈特尔书约2年前未成功，所以现在我拥有所有这些不同的东西安装，我不知道他们在哪里，他们是什么，或如何摆脱他们。我甚至不记得我安装的所有东西。我在OSX上10.6.8

该教程说做rails new issues所以我这样做，它说我应该看到一堆东西创建，然后打包器。我没有看到捆绑商。我发现了一些说明，另一SO张贴，并跟着他们去得到这个错误：如果我做rails -v我得到这个

Bundler could not find compatible versions for gem "bundler": 
In Gemfile: 
rails (= 3.0.1) ruby depends on 
    bundler (~> 1.0.0) ruby 
Current Bundler version: 
bundler (1.3.5) 
This Gemfile requires a different version of Bundler. 
Perhaps you need to update Bundler by running `gem install bundler`? 

现在：

另一个SO话题说，看看我是否有捆扎机安装：

xxxxx-xxxx-macbook-pro:issues Ryan$ gem list bundler 
*** LOCAL GEMS *** 
bundler (1.3.5, 1.0.22) 

所以后来因为1.0.22说使用它的存在我删除了1.3.5

xxxx-xxxx-macbook-pro:issues Ryan$ gem uninstall bundler -v 1.3.5 
Successfully uninstalled bundler-1.3.5 

不管我是否更新这个，我得到的错误。

我很迷茫。我认为rails3tutorial来自一年前，当我尝试Hartl书籍和firstapp是我试图把我正在尝试的教程的地方。如果有人有任何线索，我真的很想弄清楚。也许有一天我甚至能够通过设置并在Ruby On Rails上做一些有效的工作。

Answer 1

问题我可以propably你的过时rails版本（你使用3.0，与3.2是当前版本）。作为一般建议：尝试使用每个宝石的最新版本。

要更新你的宝石/红宝石，做一个

rvm get stable # see the note at the bottom, if that does not work 
rvm install 1.9.3 # may take some time 
rvm use 1.9.3 --default 
gem install bundler 
gem install rails 
rails new issues 

注意：如果rvm get stable不起作用，看看this SO answer。

Answer 2

幸运的是，你正在使用RVM！你可以从一个干净的石板开始，而不用担心解决旧的依赖关系。你可以安装1.9.3（你在1.9.2上），创建一个干净的gemset，并按照3.2或4.0的更新教程。让我知道你是否需要任何帮助。

你将用Rails做些有用的事情。持久性很重要。
