宝石文件将继续安装在 /home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1进行检查. 结果记录到 /home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1/ext/gem_make.out

Gem files will remain installed in /home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1 for inspection. Results logged to /home/askar/.rvm/gems/ruby-1.9.3-p429/gems/pg-0.15.1/ext/gem_make.out

推荐答案

您需要为pg gem安装本机扩展.
