安裝1.9.3，錯誤信息factory_girl需要Ruby版本> = 1.9.2

Question

我剛安裝rbenv使用Ruby 1.9.3

rbenv version 
1.9.3-p327 (set by /Users/me/.rbenv/version) 

然而，當我試圖運行包更新（一個項目，在裏面在安裝rbenv之前創建的），我得到了一個錯誤消息，factory_girl至少需要ruby 1.9.2。看到下面的錯誤消息

如果它是相關的，當我做寶石 - 版本，我看到一個參考1.8.23。

gem --version 
1.8.23 

錯誤消息

更新：

第一個答案告訴我，做三個步驟

gem install bundle 
rbenv rehash 
bundle install 

我沒有這些步驟（它安裝捆綁）「

gem install bundler 
Fetching: bundler-1.2.3.gem (100%) 
Successfully installed bundler-1.2.3 
1 gem installed 

但是當我嘗試'捆綁安裝，我得到了關於Factory_girl相同的錯誤信息。有趣的是，我決定再次嘗試這三個步驟，從gem install bunlder開始，並且再次安裝它？！＃？

Answer 1

您正在使用的bundle命令來自系統Ruby安裝，即Ruby 1.8.x.

嘗試

1. gem install bundler
2. rbenv rehash
3. bundle install

這應該解決您的問題。
