Question

这是我第一次运行Ruby on Rails。

运行“ blog ”应用程序时，我收到了消息 “我们很抱歉，但有些不对劲。我们已经收到有关此问题的通知，我们将对此进行审核不久“。

然后我检查了CODE \ blog \ log \ development.log并得到了这个：

/!\ FAILSAFE /!\  Tue Jun 30 15:22:55 +0100 2009

我已经尝试过了：

gem install sqlite3

得到了这个回应。

ERROR:  could not find gem sqlite3 locally or in a repository

我也尝试过：

gem install sqlite3-ruby

得到了这个回应。

我使用XAMPP（Apache + MySQL + PHP）运行Windows XP。

我该如何解决这个问题？

Answer 1

使用InstantRails。

它可以正确设置Windows环境而不会有任何麻烦。

安装InstantRails后，可以通过在安装目录中找到.exe来启动GUI。然后点击“我”图标 - ＆gt; Rails应用程序 - ＆gt;打开Ruby控制台窗口以打开控制台。

运行“gem update --system”和“gem update rails”以获取最新的RoR，因为此时InstantRails还有几年的历史。

Answer 2

对于需要编译扩展的Ruby附加组件，Windows可能很难正确配置，其中SQLite可能就像查找C头文件一样。

安装包含gcc和nmake的完整Cygwin环境可能有助于解决其中一些问题。

尽可能尝试查找所需插件的二进制版本以避免此类问题。

Answer 3

目前，您遇到的问题已经解决。

我建议阅读this tutorial，它解释了使用较新的Ruby安装程序for Windows设置Ruby + SQLite3的所有步骤。

指令的唯一更新将是从RubyForge下载最新的RC1，如this news announcement

中所述

希望有所帮助。

Answer 4

一旦你接受在Ruby世界中，Windows版本往往落后于* nix的版本，这很简单。

Rails Wiki上有说明（向下滚动到“Windows”部分）。他们建议将sqlite3.dll文件放在windows / system32中，我个人不愿意这样做。 PATH上的任何地方都可以：我把它放在ruby / bin中，我自己。

Answer 5

根据Joe Schneider的建议尝试更新InstantRails时，您可能会收到一些HTTP 403或503错误（我几天前做过）。由于InstantRails很老，因此无法直接更新。查看这篇文章，您将在几分钟内启动并运行，我甚至不愿意在Windwos上安装ruby - InstantRails是要走的路......
