无法使用JRuby安装SQLITE3 [英] Cannot install SQLITE3 with JRuby

问题描述

我是Ruby的新手，并且使用Windows7.这与我通常所用的环境不同，因此在进行一个简单的项目时遇到了问题.

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.

在阅读了几本教程之后，看来JRuby是在Windows上运行的最简单方法.我现在正尝试从头开始创建Web应用程序，但是我对这种Shell样式的工作方法感到困惑.

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.

我下载了sqliste3.def，sqlite3.dll和sqlite3，并将它们放在以下位置: C:jruby-1.6.4> bin 目录.但是，我现在正在尝试安装sqlite，但无济于事.首先，我想知道的是哪个控制台环境可以做到这一点.这是cmd还是IRB控制台?

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?

每当我使用cmd时，默认行是c:\ users \ me>，我不知道这是否影响事情的正常运行.

Whenever I use cmd the default line is c:\users\me> and I don't know if this is affecting how things should work.

每当我尝试安装SQLITE3时，我都假设我需要去:

Whenever I try to install SQLITE3 I am assuming that i need to go :

c:\users\me>gem install sqlite3-ruby

但是我什么都没收到并收到以下错误:

However I am not getting anywhere and receiving the following error:

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，我只是试图用联系表单构建一个基本网页，但是我似乎在项目安装中遇到了各种各样的问题，并且只是在启动和运行ruby.是否有任何教程可以说明如何从头开始使用JRuby和Sqlite3启动Web项目?

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?

推荐答案

如警告所示，sqlite3-ruby需要本机C扩展，并且不适用于JRuby.

As the warning suggests, sqlite3-ruby requires native C extension, and it does not work well with JRuby.

您应该改用activerecord-jdbcsqlite3-adapter.

https://rubygems.org/gems/activerecord-jdbcsqlite3-adapter
