Hi every:
I’m trying to install postgres gem but since I have latest postgres
version then some problems appears. When I run gem install postgres I
get this:

You probably miss the libpq-dev package.

If you still face problems, what is your exact version of Operating
System ?
HTH,

I don’t think so because I installed PostgreSQL using this guide[1] and
there -devel packages are installed. Anyway I’m using CentOS 6.2. I’ve
try to create a project and get SQLite problems the force postgresql as
database and get this errors:

Make sure that gem install pg -v '0.13.2' succeeds before bundling.
This is the correct gem? pg? Any other help on get RoR and PostgreSQL up
and running?

So, it fails; where is pg_config, and have you followed the directive
to try building with that path?

Can’t find the 'libpq-fe.h header
So what’s unclear about that? If you believe the required files are
on your system, find them and provide the correct path to the gem
installer. And if they’re not, install them

This time you left off the additional ‘–’ after gem install pg - you
had
it in there the time before. It tells gem the following flags are for
the
specific gem you’re installing, not for the gem command itself.

Just go one step at a time. Here’s exactly what works on my Mac:
gem install pg –
–with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
You should be able to just substitute the appropriate location for
your own pg_config file.

Ok, sorry I found the directory in another place so all the time I was
wrong thinking in config files and because of that I use
/var/lib/pgsql/9.1/data and not /usr/pgsql-9.1/bin/pg_config as should
be from the beginning. So aplogies once more time

What’s unclear about it is that it doesn’t fucking work.
Been there, done that, the error message and instructions are incorrect;
providing the path to pg_config does not work, even when the postgres
install is completely default with everything in the standard location.
It’s a bit frustrating that I can’t find my notes right now, but
basically nearly all the results from google searches are really bad
advice, and what is required is to use the option that specifies the
root of the postgres install.

Does that path end with a file named ‘pg_config’? No. It does not.
So, again, nothing like the example I gave you.

If there is a reproduceable bug in core Postgres, please show me here
so I can resolve it.
