我正在使用Ubuntu 12.10 64位版本,并安装了以下软件包:
dpkg --get-selections | grep postgre
输出:

postgresql-client-9.1
postgresql-client-common
postgresql-common
postgresql-contrib
postgresql-contrib-9.1
postgresql-server-dev-9.1

rvm 1.17.9
ruby 1.9.3p362 (2012-12-25 revision 38607) [x86_64-linux]
我无法安装pg gem,出现以下错误:
ERROR: Error installing pg:

我也尝试了以下命令,但输出结果与上面相同:
gem install pg -- --with-pg-include=/usr/include/postgresql/libpq --with-pg-lib=/usr/lib/postgresql/9.1/lib
gem install pg -- --with-pg-include=/usr/include/postgresql --with-pg-lib=/usr/lib/postgresql/9.1/lib
