安装nokogiri的gem devkit(windows)时缺少libxml2

我一直在经历这个gem的很多问题,所以我读到我必须使用de 1.5.0-beta。

由于我使用的是Windows,我下载了DevKit。 但当我跑:

gem install nokogiri –pre –withwith xml2-lib –with-xslt-lib

我明白了:

Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension.

Results logged to C:/Ruby187/lib/ruby/gems/1.8/gems/nokogiri-1.5.0.beta.4/ext/no kogiri/gem_make.out 

我能做什么?

用像这样的命令

 gem install nokogiri --pre -- --with-xml2-lib --with-xslt-lib 

看起来你正在尝试安装最新版本的nokogiri。 尝试使用--version指定精确版本。

另请注意nokogiri 1.6+的以下要求

  • ruby1.9.3或更高
  • 在Nokogiri 1.6.0及更高版本中,不再需要libxml2和libxslt

所以,如果你确实想使用ruby 1.8.7(这是EOL,顺便说一句)那么,是的,你需要指定nokogiri <1.6。 但是,如果你可以使用现代的生活红宝石,那么你可能会躲避lib依赖。
