在軌道上設置紅寶石的問題

Question

我剛剛開始通過“ Lynda Ruby on Rails 3基本培訓”學習Rails上的ruby。

我完成了安裝，並通過編寫“ rails new app”創建了Rails應用程序。 之后，當我寫了“ rails server”時，我看到的是：

C:\Users\Oded\sites\simple_cms>rails server
C:/Ruby192/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6-x86-mingw32/lib/mysql2/mysql2.r

您能幫我找到解決方案嗎？

Answer 1

您必須轉到該網站並按照說明進行操作...

http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/

或總之從mysql或鏡像站點下載本文中提到的連接器

運行以下命令：

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32

確保您有正確的路徑到沒有空格的mysql連接器文件夾！

完成此操作后，請確保您從解壓縮並下載的連接器庫中復制libmysql.dll文件，並將其放置在Ruby \\ bin文件中。

之后，刪除連接器庫，並通過鍵入“ rails server”啟動它，以確保您的gem文件中包含一行gem 'mysql'或gem 'mysql2'我不確定是哪一個，因此請嘗試兩者。 很爛，他們真的需要為Windows修復此問題。

Answer 2

看來您缺少一些寶石！ 嘗試運行bundle install ...然后一切正常。

編輯：確保您的Gemfile包含以下行

gem 'mysql'

在運行bundle install之前。 Bundler將為您設置mysql，依賴項和所有內容。
