我正在安装Redmine，因为rake问题我变得疯狂了。特别是，为了对不同的Ruby插件执行bundle安装，我被要求安装xapian-full-alaveteli，v 1.2.9.5。 问题是我收到以下错误：
Building native extensions. This could take a while...

我尝试手动编辑rakefile并删除导致麻烦的行，但它神奇地重新出现。关于使用rake / gem的文档，imho，至少是模糊的，因此我完全陷入困境 - 两天前应该投入生产的服务器......
答案 0 :(得分：3)
对Config的过时调用可能导致错误。尝试更改
Config::CONFIG ====> RbConfig::CONFIG
运行Gem的rakefile导致错误：未初始化的常量配置。
谷歌搜索建议Config is obsolete and to replace it with RbConfig. RbConfig位于最新的Ruby though the document is blank和I cannot find a Config in Ruby中。
修复使用RbConfig替换Config：gettalong/kramdown和thoughtbot/cocaine。这也适用于我的情况。
将Config::CONFIG替换为RbConfig::CONFIG
