rails postgresql database connection

I am trying to use a postgresql database for my rails app.

I followed the tutorials provided in this link:

http://blog.crowdint.com/2010/10/27/working-with-postgresql-and-rails3.html

I successfully installed postgresql with this command:

sudo apt-get install postgresql postgresql-client postgresql-contrib libpq-dev libpgsql-ruby libgda-4.0-postgres libpq-dev

When I reached the line to create a user I entered this command:

sudo -u postgres psql template1

But after I entered a password for root it gave me an error saying

env开发者_StackOverflow社区: -u: No such file or directory

Any idea why the error popped up?

It sounds like the environment/path may be messed up for your user. I'm not sure if you're running on mac or linux/unix but I found a post from the Ubuntu forums that may be related to your problem:

sudo is broken

I'm not sure if alias'ing sudo (page 2 reply)

alias sudo='sudo env PATH=$path'

is the best permanent solution but it fixes it for him. I have no such alias on my sudo so I'm thinking there's a better solution via profile / export command and would invite someone to provide a better answer.

Hope this helps
