在Windows 7 x64上运行redcar 0.8.1

Question

我试图让redcar在windows 7 x64框上运行，但我得到了以下错误：

Redcar 0.8.1 ( java )

这个错误似乎表明SWT存在32位版本的问题.由于基于eclipse的应用程序在我的机器上运行良好，所以我想这里缺少了一些东西。

安装redcar的步骤：

下载并安装jruby (使用64位executable)

• run jruby -S gem install redcar来安装redcar gem

• 运行redcar install

)。

我也尝试从源代码安装，但结果是一样的。

Answer 1

Redcar还不支持Win64。不是因为什么特别的原因，我们只是在接近它。

如果要使其工作，请将64位swt jar复制到win32.jar ( ~/.redcar/jars中的)之上。

如果这不起作用，那就联系。

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