即使在安裝捆綁軟件后，Rails Server也會退出

Question

我正在嘗試從“ Agile Web Development with Rails 4th edition”這本書中運行depot_a rails3.1.0示例，可以在此處下載。

我遇到了各種各樣的錯誤，即使在調用rails server之前運行bundle install后也無法識別。 任何想法如何解決這個問題？

謝謝。

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Answer 1

您是否在使用ruby 1.8.x？ 似乎您使用的是1.9.x樣式的哈希符號，而1.8.x無法解密

代替

hash = { a: 1, b: 2}

您應該使用：

hash = { :a => 1, :b => 2 }

問題出在config/initializers/session_store.rb:11 ，如果仍然卡住，請發布此行的代碼。

Answer 2

如果您已遵循Rails入門並且在Mac OS X Lion上運行

rvm use --default 1.9.2

跑步前

rails server

希望能有所幫助。
