安装json（1.7） .5）与本机扩展 Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展。 /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in`require'：can not load such file - mkmf（LoadError） from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in`require' from extconf.rb：1：in<<主要>' Gem文件将保留安装在/home/jack/.bundler/tmp/10426/gems/json-1.7.5中进行检查。 记录到/home/jack/.bundler/tmp/10426/gems/json-1.7.5/ext/json/ext/generator/gem_make.out 的结果安装json时发生错误（1.7 .5）和Bundler无法继续。 确保`gem install json -v'1.7.5'`捆绑成功。 jack @ jack-ThinkCentre：〜/ rails_projects / sample_app

我无法安装宝石单独或捆绑安装。我用rvm来安装rails。在安装ruby1.9.1-dev软件包时应该为你解决这个问题。 sudo apt-get install ruby​​1.9.1-dev

Hey I am new to rails (as well as linux) and I keep getting this error:

Installing json (1.7.5) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:1:in `<main>' Gem files will remain installed in /home/jack/.bundler/tmp/10426/gems/json-1.7.5 for inspection. Results logged to /home/jack/.bundler/tmp/10426/gems/json-1.7.5/ext/json/ext/generator/gem_make.out An error occurred while installing json (1.7.5), and Bundler cannot continue. Make sure that `gem install json -v '1.7.5'` succeeds before bundling. jack@jack-ThinkCentre:~/rails_projects/sample_app$

I cant install the gem individually or with bundle install. I used rvm to install rails. thanks in advance.

Installing the ruby1.9.1-dev package should fix this for you

sudo apt-get install ruby1.9.1-dev
