Question

我的操作系统：windows xp，ruby：1.8.7，rails：2.3.5

一切都很好，但我刚刚安装了“gcc-4.4.0-mingw32-bin”，并运行gem install rdiscount，然后我的导轨无法启动。

现在，当我运行ruby script/server或rake gems:install时，会出现以下错误：

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我的ruby和rails，但仍然会出现同样的错误。我在谷歌搜索过，发现没有解决方案。看来我必须重新安装我的Windows XP。有人知道原因吗？帮助...

Answer 1

刚才，我找到了解决方案：删除“vendor / gems”下的文件

原因可能是我在安装rake gems:unpack后运行gcc，因此一些无效文件被解压缩到“gems”目录。删除后，一切正常。

Answer 2

问题是您已经解压缩了一个具有特定于Windows的本机扩展构建的gem。这种宝石的后缀包括mingw32（例如nokogiri-1.4.3.1-x86-mingw32）。执行rake gems:unpack后，您应删除此类解压缩的文件夹。

一方面，这可以避免格式错误的版本字符串问题（您报告的问题）。另一方面，用户和具有不同操作系统的服务器（linux / mac osx）能够自己构建gem的原生扩展（不适用于Windows版本）。

启动轨道时出现“格式错误的版本号字符串mingw32”
