rake: NameError: 未初始化的常量配置

Question

我正在安装 Redmine，但由于抽成问题，我快疯了。特别是，为了对不同的 Ruby 插件执行捆绑安装，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...
ERROR:  Error installing xapian-full-alaveteli:
ERROR: Failed to build gem native extension.

我已经尝试手动编辑 rakefile 并删除导致问题的行，但它神奇地重新出现了。关于使用 rake/gem 的文档，恕我直言，至少是模糊的，因此我完全被困住了——两天前应该在生产中的服务器......

Answer 1

总结

对 Config 的过时调用可能会导致错误。尝试改变

Config::CONFIG    ====>    RbConfig::CONFIG

详细

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谷歌搜索建议 Config is obsolete and to replace it with RbConfig.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 在最新的 Ruby 中 though the document is blank和 I cannot find a Config in Ruby .

修复将 Config 替换为 RbConfig:gettalong/kramdown和 thoughtbot/cocaine .这也适用于我的情况。

结论

将 Config::CONFIG 替换为 RbConfig::CONFIG
