ruby-on-rails – 无法在Fedora 17上安装PG gem

pg gem很顽固,所以我无法在新电脑上加载我的应用程序.看起来像多个问题,无法找到pg_config,然后是extconf.rb

#psql working...
psql (9.2.1)
Type "help" for help.

nd =>
q

$pg_config:

#adding the path to bashrc...
$nano .bashrc

PATH=/usr/pgsql-9.2/bin:$PATH

#seems to work...
pg_config: /usr/pgsql-9.2/bin/pg_config

$sudo gem install pg

#but i get the same errors...
Building native extensions.  This could take a while...
.......
ERROR:  Error installing pg:
        ERROR: Failed to build gem native extension.

        /usr/bin/ruby extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails,please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason,probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

有没有处理过这个问题的linux人？ 最佳答案 这是通过解决的

$yum install /usr/include/libpq-fe.h
