我在這裏失蹤的是什麼？ mysql2在我的Gemfile裏面。

雖然我沒有將我的導軌連接到我的數據庫或配置database.yml，因爲我找不到有關如何做到這一點的任何說明。

Answer 1

基本上following the instructions in here 我剛剛完成安裝從零到64位Windows 7功能齊全。

在你的情況下，問題可能在於版本的寶石mysql2或它的安裝方式;你可以從卸載開始並重新安裝0.2.6版本@see Gediminas answer並檢查GemFile是否有不同的版本。 這把我從煩惱與特定的：

--with-mysql-dir=.... --with-mysql-lib=.... --with-mysql-include=....

---

無論如何，我將詳細介紹我的清單中的每個步驟，這樣你就可以看看是否有你的安裝不同

• 已安裝mysql-installer-community-5.6.24.0.msi來自http://dev.mysql.com/downloads/mysql/ 在我的個人中ecklist 這些是我選擇的組件： ..我選擇連接選項： ..和帳戶/安全選項：

• 安裝了Ruby rubyinstaller-2.1.6.exe從http://rubyinstaller.org/downloads/

注：根據http://rubyinstaller.org/downloads/我選擇2.1 *（不是最後一個），我下載了標準32。因爲64位版本的Ruby在Windows領域相對較新，並且並未將所有軟件包都更新爲與其兼容。要使用這個版本，你需要一些關於編譯器和解決依賴問題的知識，如果你只是想玩這個語言，這可能太複雜了。 紅寶石2.0.0和上述 - >：在同一頁上 另外閱讀mingw64-32-4.7.2

• 從http://rubyinstaller.org/downloads/安裝紅寶石的devkit DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe（萃取到C:\DevKit）
• 別別忘了設置的的devkit

cd C:\DevKit 
ruby dk.rb init 
ruby dk.rb install 
devkitvars.bat 

• 不要忘記我的情況下複製libmysql.dll，具有相同的名稱安裝MySQL社區5.6我發現了三個不同的dll（在尺寸上）後：

cd \ 
find . -name "libmysql.dll" 
./Program Files/MySQL/MySQL Connector.C 6.1/lib/libmysql.dll 
./Program Files/MySQL/MySQL Server 5.6/lib/libmysql.dll 
./Program Files/MySQL/MySQL Workbench 6.2 CE/libmysql.dll`` 

明確我選擇此選項：

C:>cd C:\Ruby21\bin> 
C:\Ruby21\bin> copy "\Program Files\MySQL\MySQL Server 5.6\lib\libmysql.dll" . 
     1 file(s) copied. 

• 我有一些問題在安裝寶石因此，我決定更新rubigems，this helps me a lot.

準備安裝導軌和創建第一個應用程序：

gem install rails 

gem install mysql2 -v 0.2.6 

rails new test_app -d mysql 

在結束最後一個步驟：

1. 連接的MySQL Workbench和創建了一個名爲 test_app_development新的模式（以創建一個新的模式，你可以按與缸和一個加號工具欄上的圖標4 ..請參閱下一屏截圖）

2. 固定的用戶名和密碼在config/database中。陽明海運在sansarp anwser

3. 遷移的數據庫

遷移模式後，應該是這樣的：

Answer 2

在配置/ database.yml中有如下設置你的開發環境：

development: 
    adapter: mysql2 
    database: db_name 
    username: your_username 
    password: your_password
