PostgreSQL gem pg was unable to install
try installing libpq package by doing:
sudo apt-get install libpq-dev
That package helps with pg gem and you should be fine after that :)
Here's my recipe for getting PostgreSQL, RVM, Ruby, Rails all up and running on CentOS
PostgreSQL
First, follow the instructions on http://wiki.postgresql.org/wiki/YUM_Installation to get PostgreSQL installed:
sudo vi /etc/yum.repos.d/CentOS-Base.repo
[base]
exclude=postgresql*
[updates]
exclude=postgresql*
Get the latest PGDG RPM file (for your platform/architecture), for example:
curl -O http://yum.postgresql.org/9.2/redhat/rhel-latest-x86_64/pgdg-redhat92-9.2-7.noarch.rpm
Then
sudo rpm -ivh pgdg-redhat92-9.2-7.noarch.rpm
sudo yum install -y postgresql92-server postgresql92-devel
Initialize the database:
sudo service postgresql-9.2 initdb
Configure /var/lib/pgsql/9.2/data/postgresql.conf
and /var/lib/pgsql/9.2/data/pg_hba.conf
as needed.
Start PostgreSQL server:
sudo service postgresql-9.2 start
RVM
sudo yum -y groupinstall "Development Tools"
sudo yum -y install zlib zlib-devel sqlite-devel httpd curl-devel httpd-devel apr-devel apr-util-devel mlocate man libxml2-devel libxslt-devel libffi-devel readline-devel
Note, NOT as root:
\curl -L get.rvm.io | sudo bash -s stable
Logout and back on. Afterwards, which rvm
should reply with /usr/local/rvm/bin/rvm
and type rvm|head -1
should say rvm is a function
.
Ruby + Rails
rvm install 1.9.3 --with-openssl-dir=/usr
rvm use 1.9.3 --default
gem install rake
gem install rails
PostgreSQL gem
gem install pg -- --with-pg-config=/usr/pgsql-9.2/bin/pg_config
The --with-pg-config
is somehow needed with my latest installation of CentOS, otherwise, gem install pg
can't find pg_config
. YMMV, but if you follow all the above to the letter (which I've done enough times in the past few months) just let me know if anything trips you up.
I got the same error on Centos. By googling I found two commands to use:
yum install postgresql-libs
-- It gave me message saying, its already installed.yum install postgresql-devel
-- It solved my error related topg_config
for installing the 'pg' .gem.
Hope it helps :)
