[英]How to fix `require': cannot load such file — nokogiri/2.1/nokogiri (LoadError)
I see many answers for this error when ruby version is =>2.2, but in my computer installed ruby version is [ruby 2.1.8p440] I get this error when starting a server ( rails server ).当 ruby 版本 =>2.2 时,我看到很多关于此错误的答案,但在我的计算机上安装的 ruby 版本是 [ruby 2.1.8p440] 启动服务器( rails server )时出现此错误。
