更新rails版本後無法運行rake

Question

我已經升級到rails 2.3.11和ruby 1.9.2，因爲我的一些寶石與以前的版本不兼容。現在我無法執行rake命令。當我做耙寶石時出現以下錯誤：install或rake db：migrate。

您可能需要升級rubygems-update。

運行gem -v查看您當前的版本號。

運行gem update --system升級rubygems。 （您可能需要須藤根據您的設置）

要恢復到以前的版本，運行gem update --system 1.3.7（交換1.3.7之前的版本號）

Answer 2

看起來像瑞克版本的問題給我。試試這個...

gem uninstall rake # select all options 
gem 'rake', '0.8.7' # Gemfile 
bundle install 
run you rake command 

配售這行代碼在你.rvmrc您的根目錄將允許您跳過小錯誤這樣的未來。

bundle exec $SHELL 

所有最好的，讓我們知道你是如何得到。

你應該想辦法解決寶石引發耙子的衝突。嘗試運行服務器，如果你成功了，這意味着你可以運行Rake，它與Rake版本befre運行rake無關，爲rails提供一個有效的gem列表。
