我似乎無法無差錯運行包更新。我使用Fedora 15和Mysql 5.5運行我的機器。

再次感謝，我爲我的無知道歉;我是Rails的新手。

在此先感謝！ :)

Answer 1

看起來你應該在你的Gemfile限制mysql2版本：

gem 'mysql2', '~>0.2.0' 

[編輯] ...然後做一個bundle install當然

Answer 2

的，正如我們所看到的日誌，我想你已經指定mysql作爲你的config/database.yml中的適配器

更改爲：

adapter: mysql2 

編輯：

你FormatError，我知道我必須使用：

bundle exec rake db:<command> 

現在爲了執行耙，你可以試試這個？

編輯2：

那麼，我建議你使用RVM設置使用Ruby 1.9.2項目。 Read RVM Doc一個簡單的指導如何做到這一點。

然後做一個捆綁安裝

之後，你一定要做：

ruby -v 

應該是1.9.2

然後重試分貝：創建這樣的：

bundle exec rake db:create:all 

希望它終於有效。 ;-)

Answer 3

爲了擺脫RubyGems的廢棄警告更新到最新版本RubyGems的和運行

gem pristine --all --no-extensions。

至於你的mysql錯誤。確保你打開了MySQL服務/守護進程並確保你的database.yml配置文件是正確的。
