Gem::Load error

[Benyamin Pm]

hi everyone..
i install rails and all the things which is need for.
i create a new project
i create datbase's and set the database.yml file

but when i go to browser and type this=> localhost:3000. i get this
error=>

Gem::Loaderror

Specified 'postgresql' for database adapter, but the gem is not loaded.
Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum
required by ActiveRecord).

for fixing it i uninstall all the gems and reinstall all of them.
but again i have this error.

What does your Gemfile look like? Does it have the pg gem listed?

[James Jelinek (shakycode)]

Ok, but would you mind posting your Gemfile in a github gist so we can look at it? What happens when you run “bundle install” from the command line? Does it install all of the gems in your Gemfile?

I suggest you start by working right through a good tutorial such as
railstutorial.org (which is free to use online). This can be worked
through using a development environment in the cloud so there is no
need to worry about whether you have the right stuff installed on your
machine. Once you have worked through the tutorial you should have a
grasp of the basics or RoR and be ready to go with your own projects.
The couple of days spent will be very soon recovered in saved time
during the next phase of your learning.

bundle install work's perfectly and don't return any error.

Bundle complete! 12 Gemfile dependencies, 54 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

[Scott Eisenberg]

How about giving us the output of bundle list? Or at the very least bundle list pg?

PS If you see pg listed there you’re gonna have to give more information like the stacktrace, error messages in the server window, your database.yml file.

If you want help at least give us a fighting chance...

hi scott.


please take a look at this =>

[Colin Law]

Why is it apparently so difficult for people to supply the information
asked for? Please just copy/paste your Gemfile here so that we can
see it. We don't want to have to look at screenshots, and even on the
screenshot you have not shown Gemfile.

Also please post Gemfile.lock

Also what version of Ruby are you running?

[nanaya]

- the output of `bundle list pg` says "Could not find gem 'pg'."
- the error page says "Add `gem 'pg'` to your Gemfile"

Have you read it? And have you actually done it? (hint: `gem install pg`
is not the same thing)

That is not the file Gemfile which is a file in the top level of your application. You need to add pg to that and run bundle. The fact you did not realise this shows that you really need to work through the tutorial that I suggested.

I don't see pg in there. As has been pointed out numerous times
already the error message says you need to add pg to Gemfile. Also
you can take out sqlite3, under the line that says

> # Use sqlite3 as the database for Active Record

How are you getting on with the tutorial?

i just edit source url from https://rubygems.org to http://rubygems.org
and add gem 'pg' in Gemfile after like this=>

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.5'

gem 'pg'


and i go to terminal and type 'gem install pg'

You should have run
bundle install
or just
bundle
there is no need to run gem install pg though it will not do any harm.

I am surprised the error is gone if you have not run bundle install or bundle.
