Ruby on rails &引用；格式错误的版本号字符串mingw32“；启动轨道时

我的操作系统：WindowsXP、ruby:1.8.7、rails:2.3.5

一切都很好，但我只是安装了一个“gcc-4.4.0-mingw32-bin”，然后运行

gem install rdisont

，然后我的rails无法启动

现在，当我运行

ruby脚本/server

或

rake gems:install

时，将发生以下错误：

rake aborted!
Malformed version number string mingw32

(See full trace by running task with --trace)

现在我已经重新安装了ruby和rails，但同样的错误仍然发生。我在谷歌上搜索，没有找到解决方案。看来我必须重新安装我的windows xp。有人知道原因吗？帮助…

刚才，我找到了解决方案：删除“供应商/宝石”下的文件

---

原因可能是我在安装了

gcc

之后运行了

rake gems:unpack

，因此一些无效文件被解压缩到了“gems”目录。在我删除它们之后，一切都正常。

问题是您已经解包了一个gem，其中包含一个特定于Windows的本机扩展构建。这种gem的后缀包括mingw32（例如nokogiri-1.4.3.1-x86-mingw32）。执行

rake gems:unpack

后，应该删除这些未打包的文件夹

另一方面，这避免了格式错误的版本字符串问题（您报告的问题）。另一方面，使用不同操作系统（linux/mac osx）的用户和服务器能够自己构建gem的本机扩展（不适用于windows版本）
