Rails -v給我的錯誤和唯一的解決方案，我發現給出了不同的錯誤

Question

我試圖起牀和運行下面的教程，但我曾嘗試使用哈特爾書約2年前未成功，所以現在我擁有所有這些不同的東西安裝，我不知道他們在哪裏，他們是什麼，或如何擺脫他們。我甚至不記得我安裝的所有東西。我在OSX上10.6.8

該教程說做rails new issues所以我這樣做，它說我應該看到一堆東西創建，然後打包器。我沒有看到捆綁商。我發現了一些說明，另一SO張貼，並跟着他們去得到這個錯誤：如果我做rails -v我得到這個

Bundler could not find compatible versions for gem "bundler":

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`? 

現在：

另一個SO話題說，看看我是否有捆紮機安裝：

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

所以後來因爲1.0.22說使用它的存在我刪除了1.3.5

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

不管我是否更新這個，我得到的錯誤。

我很迷茫。我認爲rails3tutorial來自一年前，當我嘗試Hartl書籍和firstapp是我試圖把我正在嘗試的教程的地方。如果有人有任何線索，我真的很想弄清楚。也許有一天我甚至能夠通過設置並在Ruby On Rails上做一些有效的工作。

Answer 1

問題我可以propably你的過時rails版本（你使用3.0，與3.2是當前版本）。作爲一般建議：嘗試使用每個寶石的最新版本。

要更新你的寶石/紅寶石，做一個

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

幸運的是，你正在使用RVM！你可以從一個乾淨的石板開始，而不用擔心解決舊的依賴關係。你可以安裝1.9.3（你在1.9.2上），創建一個乾淨的gemset，並按照3.2或4.0的更新教程。讓我知道你是否需要任何幫助。

你將用Rails做些有用的事情。持久性很重要。
