无法使用 JRuby 安装 SQLITE3
我对 Ruby 很陌生，并且使用的是 Windows 7。这与我通常习惯的环境不同，因此我在运行一个简单的项目时遇到了问题。
阅读了几个教程后，我发现 JRuby 是在 Windows 上运行的最简单的方法。我现在正在尝试从头开始创建一个 Web 应用程序，但我对这种 shell 风格的工作方法感到困惑。
我已经下载了 sqliste3.def、sqlite3.dll 和 sqlite3，并将其放入： C:jruby-1.6.4>bin 目录。但是，我现在尝试安装 sqlite 但没有成功。首先，我想知道使用哪个控制台环境来执行此操作。这是 cmd 还是 IRB 控制台？
每当我使用 cmd 时，默认行是 c:\users\me>我不知道这是否会影响事情的运作。
每当我尝试安装 SQLITE3 时，我都假设我需要去：
c:\users\me>gem install sqlite3-ruby
但是我没有到达任何地方并收到以下错误：
WARNING:JRuby does not support native extensions or the 'mkmf' library very well
我听说过很多关于 Ruby 的好东西，我只是尝试构建一个带有联系人的基本网页形式，但我似乎在项目安装和简单地启动并运行 ruby 时遇到了各种问题。是否有任何教程解释如何从头开始使用 JRuby 和 Sqlite3 启动 Web 项目？
I am brand new to Ruby and using Windows 7. It is a different environment to what I am normally used to so I am having problems getting a simple project going.
After reading several tutorials, it appears that JRuby is the simplest way to go on windows which I have done. I am now trying to create a web application from scratch but I am confused about this shell style method of working.
I have downloaded sqliste3.def, sqlite3.dll and sqlite3 which I have put in the:
C:jruby-1.6.4>bin
directory. However, I am now trying to install sqlite but with no avail. Firstly what I would like to know is which console environment does one use to do this. Is this cmd or the IRB console?
Whenever I use cmd the default line is c:\users\me> and I don't know if this is affecting how things should work.
Whenever I try to install SQLITE3 I am assuming that i need to go :
c:\users\me>gem install sqlite3-ruby
However I am not getting anywhere and receiving the following error:
WARNING:JRuby does not support native extensions or the 'mkmf' library very well
I have heard a lot of good things about Ruby and I am simply trying to build a basic webpage with a contact form but I seem to be running into all sorts of issues with the project installation and simply getting ruby up and running. Are there any tutorials that explain how to start a web project with JRuby and Sqlite3 from scratch?

正如警告所示，
sqlite3-ruby需要本机 C 扩展，并且它不能很好地与 JRuby 配合使用。您应该改用
activerecord-jdbcsqlite3-adapter。https://rubygems.org/gems/activerecord-jdbcsqlite3-adapter
请参阅https://github.com/jruby/activerecord-jdbc-adapter
As the warning suggests,
sqlite3-rubyrequires native C extension, and it does not work well with JRuby.You should use
activerecord-jdbcsqlite3-adapterinstead.https://rubygems.org/gems/activerecord-jdbcsqlite3-adapter
See https://github.com/jruby/activerecord-jdbc-adapter
