在Windows上安装SQLite3 for Ruby - 目前最简单的路线是什么？

Question

我是Ruby的新手,希望让Redmine在WinServer08 sp1上运行

我在这里阅读了一些线程,详细介绍了让Ruby和SQLite相互配合所需的步骤和变通方法.

Ruby会运行... sqlite3的.dll和api都在指定的目录中......我重新启动但是rake -test失败了.

我想知道是否有一个明确的循序渐进,汇总了所涉及的各种包的先前解决方法. - 太多了!

C:\Ruby>rake -test --trace

即使database.yaml配置文件已预先配置为使用Sqlite,但Windows版本的Ruby on Rails不随Sqlite3数据库一起提供.

这是如何指导如何在Windows PC上安装Sqlite3.本文假设您已经在PC上安装了Ruby和Ruby on Rails.

首先,您需要从Sqlite网站http://www.sqlite.org/download.html下载两个文件:

sqlite-3_5_9.zip (214.32 KiB)
A command-line program for accessing and modifing SQLite databases. 
See the documentation for additional information.

sqlitedll-3_5_9.zip (213.17 KiB)
This is a DLL of the SQLite library without the TCL bindings. 
The only external dependency is MSVCRT.DLL.

第一个文件是用于修改Sqlite数据库的Sqlite命令行程序.您可能会也可能不会使用此功能.

第二个文件是Windows DLL库文件,当Rails进行Sqlite数据库调用时,Ruby使用它.

解压缩这两个ZIP文件后,您应该拥有以下文件:

• sqlite3.exe
• sqlite3.def
• sqlite3.dll

将这些文件复制到Ruby安装的bin目录中,如果您遵循默认的Ruby安装,它将位于此处:

C:\ruby\bin

现在您已经安装了Sqlite3文件,您需要告诉Ruby如何使用它们.为此,您需要下载Sqlite3的Ruby绑定.幸运的是,使用Ruby宝石很容易做到这一点.只需在命令提示符下键入以下命令:

gem install sqlite3-ruby

您现在需要告诉Gems您需要哪个版本,因为您将看到以下输出:

Bulk updating Gem source index for: http://gems.rubyforge.org
Select which gem to install for your platform (i386-mswin32)
 1. sqlite3-ruby 1.2.2 (mswin32)
 2. sqlite3-ruby 1.2.2 (ruby)
 3. sqlite3-ruby 1.2.1 (mswin32)
 4. sqlite3-ruby 1.2.1 (ruby)
 5. Skip this gem
 6. Cancel installation
>_

请选择选项1,sqlite3-ruby 1.2.2(mswin32).一切都成功,你会得到一些这样的输出:

Successfully installed sqlite3-ruby-1.2.2-mswin32
Installing ri documentation for sqlite3-ruby-1.2.2-mswin32...
Installing RDoc documentation for sqlite3-ruby-1.2.2-mswin32...

如果您使用的是Rails 2+,则应该可以从Rails应用程序目录运行以下rake任务.例如,假设您创建了一个位于此处的Rails应用程序:C:\ MyApp您应该能够执行:

C:\MyApp>rake db:create
or
C:\MyApp>rake db:migrate

祝好运 !
