服务器安装陷入错误:无法在任何源(Bundler::GemNotFound)中找到pg-0.17.1

Question

试图让Ruby2.0.0在CentOS 6.5上运行，并使用nginx和客运。到目前为止，由于错误而没有运气：http://prntscr.com/3egoca

这是我用于安装用于Ruby的PostgreSQL服务器的过程：

sudo vi /etc/yum.repos.d/CentOS-Base.repo

# In both [base] and [updates] sections I added the following line to the file above:
# exclude=postgresql*

sudo rpm -Uvh http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm
sudo yum install postgresql93 postgresql93-devel postgresql93-server postgresql93-libs postgresql93-contrib
sudo /etc/init.d/postgresql-9.3 initdb
sudo service postgresql-9.3 start
sudo chkconfig --levels 235 postgresql-9.3 on

# At the bottom of this file I changed authentication method to md5:
sudo vi /var/lib/pgsql/9.3/data/pg_hba.conf
sudo service postgresql-9.3 restart

到目前为止，在测试时，PostgreSQL运行得很好，但这是它失败的地方：

bundle install

这给了我一个错误：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/home/deploy/.rvm/rubies/ruby-2.0.0-p451/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

*** 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.

因此，我遵循了这个建议，尝试分别安装PG宝石，如下所示：

gem install pg -- --with-pg-config=/usr/pgsql-9.3/bin/pg_config

当我尝试的时候，我得到了这个输出：

Building native extensions with: '--with-pg-config=/usr/pgsql-9.3/bin/pg_config'
This could take a while...

尽管说它安装成功，但我还是收到了我发布的截图中的乘客错误，我仍然无法让bundle install成功运行。

顺便说一句，我是SSH作为用户“部署”，这也是nginx在nginx.conf文件中设置的用户。

尝试：

export PATH=/usr/pgsql-9.3/bin:$PATH
bundle install
