不能用rvm install rails 5 gem

Question

我嘗試用ruby-2.3.1創建gemset rails500，我得到了：

 To see why this extension failed to compile, please check the mkmf.log which can be found here: /Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/extensions/x86_64-darwin-16/2.3.0/nokogiri-1.6.8.1/mkmf.log extconf failed, exit code 1 Gem files will remain installed in /Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/gems/nokogiri-1.6.8.1 

檢查。 結果記錄到/Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/extensions/x86_64-darwin-16/2.3.0/nokogiri-1.6.8.1/gem_make.out

我試圖卸載並再次安裝它，但我得到了相同的信息

我該怎么解決？

Answer 1

它可能有所幫助：

brew uninstall xz

gem install nokogiri -v 1.6.8或gem install rails （命令你正在運行）
