我正嘗試通過在線教程學習Ruby on Rails。Rails沒有正確創建新的應用程序 - 與JSON 1.7.7衝突？
[rails version]: Rails 3.2.13
[ruby version] : ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]
當我執行命令：
rails new first_app
我得到：
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /usr/share/include/ruby.h
Gem files will remain installed in /home/philippe/.gem/ruby/1.9.1/gems/json-1.7.7 for inspection.
Results logged to /home/philippe/.gem/ruby/1.9.1/gems/json-1.7.7/ext/json/ext/generator/gem_make.out
An error occurred while installing json (1.7.7), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.7'` succeeds before bundling.
果然，我跑gem install json -v '1.7.7爲上市，但是結果是：
[[email protected] rails_projects]$ gem install json -v '1.7.7'
Building native extensions. This could take a while...
ERROR: Error installing json:

有沒有人看到了嗎？
將結果中記錄的日誌記錄到/home/philippe/.gem/ruby/1.9.1/gems/json-1.7.7/ext/json/ext/generator/gem_make.out成爲要點 – rovermicrover 2013-04-09 01:06:25
