Ruby on rails：rake中止壞文件描述符

我搜索了四周，但我一直未能找到有效的答案。Ruby on rails：rake中止壞文件描述符

我對此完全陌生，所以當你回答時，就像我是一個孩子一樣解釋......或者像我是一塊西蘭花一樣解釋。如果你想要我安裝一些東西，告訴我該寫什麼。

嗯，我想按照這個http://guides.fatfreecrm.com/Setup-Microsoft-Windows.html和我來這裏，我應該寫 rake db:create RAILS_ENV=production 一個點，我得到的是這樣的：（我也做了「創業板安裝mysql2」，我已經安裝耙如在教程中，並沒有看到任何問題）

C:\RailsInstaller\fat_free_crm>rake db:create RAILS_ENV=production --trace 

** Invoke db:create (first_time) 
** Invoke db:load_config (first_time) 
** Invoke rails_env (first_time) 
** Execute rails_env 
** Execute db:load_config

您真的想要生產環境嗎？（RAILS_ENV =生產）即現場？如果沒有，然後刪除那一點。然後檢查config/database.yml並確保您已正確配置環境。 – TomDunning

是否提供了mysql的服務？你有沒有嘗試runnig只耙分貝：創建？ –

我也面臨同樣的問題。我正在嘗試這種開發模式。當我創建一個新的應用程序並嘗試執行該命令時，它會成功運行。但在我的情況下，我已經從SVN中檢出項目，並嘗試執行rake db：migrate，並面臨同樣的問題。 – Rohit

我有相同的問題，並花了兩個小時後修復它。也許它會幫助你。所以這裏的步驟，這導致我解決這個問題

我假設你正在運行32位的MySQL，因爲64位+ 32位mysql的問題可以是別的東西
確保是MYSQL.DLL compatiable安裝寶石（我有mysql2）
爲了避免問題從上下http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip/from/pick
複製MYSQL.DLL加載到你的Ruby/bin中

摘要：對我來說，在p軌道之間不兼容的問題mysql2寶石和我的機器上安裝的那個不一致
