嘗試啓動rails服務器時出現語法錯誤

我最近開始研究一個我從github克隆的項目。嘗試啓動rails服務器時出現語法錯誤

每次我嘗試啓動rails服務器我得到以下錯誤：

我collegue也在致力於該項目，並似乎不啓動服務器的任何問題。他正在運行與我一樣的Ruby，Rails和WeBrick版本。

我試着改變從鍵的語法：鍵=>，這應該不是問題，雖然我運行ruby版本1.9.3。如果我作出這樣的改變，無論如何我得到一個不同的錯誤信息：

我已經厭倦了完全拆卸和重新安裝RVM，Ruby和Rails了幾次都沒爲準。我也試過運行捆綁安裝，這沒有幫助。

有沒有人有任何想法出了什麼問題？

謝謝

嘗試將哈希值更改爲：key =>：value語法。在Rails 3.1 Deployment to Heroku Error討論相同的錯誤和修復。建議的臨時修補程序是：配置/初始化/ session_store.rb

App::Application.config.session_store :cookie_store, :key => '_BillingMiddleware_session'

配置/初始化/ wrap_parameters.rb

ActionController::Base.wrap_parameters :format => [:json]

這似乎是解決問題的快速解決方案。我只是想知道爲什麼當我運行Ruby 1.9.3時，它爲散列值的這種語法抱怨？ – MalcolmDurling

你仍然在你的系統中以某種方式使用ruby 1.8.7。至少你已經起來跑步了。祝你好運。 – Anil

許多代碼已經提交給項目，雖然有了新的語法，但是當它爲項目的其他成員工作時，似乎毫無意義地將它們全部更改回舊語法。這是我能嘗試的其他事情嗎？當我運行紅寶石-v我得到紅寶石1.9.3p194（2012-04-20修訂版35410）[x86_64-darwin11.3.0] 我使用RVM，當我運行rvm列表紅寶石時，我只得到= * ruby-1.9 .3-p194 [x86_64]我也運行rvm使用ruby-1.9.3-p194，這沒有幫助。 – MalcolmDurling

看起來像在修復那個之後的另一行上的散列語法。檢查config/intializers/wrap_parameters.rb，我想知道這個項目是否得到了「不」使用新語法的標誌？

我已經改變都不會使用新的語法，但它再次似乎在項目中使用新的語法找到更多的例子並且抱怨它們。該項目是由我的同事自己創建的，所以我堅信它不會使用新語法。他似乎能夠在他的最後沒有問題地啓動服務器。 – MalcolmDurling

你的'ruby -v'說了些什麼？你有沒有重新啓動你的控制檯選項卡也許有些奇怪的事情發生。你在獅子和他在雪豹嗎？ – pjammer

當我運行'ruby -v'時，它返回紅寶石1.9.3p194（2012-04-20修訂版35410）[x86_64-darwin11.3.0]。每次我執行更新或安裝了某些東西時，我都重新啓動了控制檯。是的，我們兩臺電腦都運行10.7.3。 – MalcolmDurling
