我试图让 redcar 在 Windows 7 x64 机器上运行，但出现以下错误：

该错误似乎表明 SWT 是 32 位版本存在问题。由于基于 Eclipse 的应用程序在我的机器上运行良好，我想我在这里缺少一些东西。

我用来安装redcar的步骤：

  • 下载并安装 jruby（使用 64 位可执行文件）
  • 运行jruby -S gem install redcar安装 redcar gem
  • 跑redcar install

我也尝试从源代码安装，但结果相同。

Redcar doesn't support Win64 yet. Not for any particular reason, we're just getting to it.

If you want to make it work, copy the 64 bit swt jar on top of the win32.jar in ~/.redcar/jars

If that doesn't do the job, get in touch.

没有足够酷的 Windows 7 恐怕我不能真正帮助你，但我认为你最好的选择是直接询问开发 Redcar 的男孩/女孩。随时向 Redcar-editor 组 (redcar-editor@googlegroups.com) 发送电子邮件。
