Making my way through the standard Rails "getting started", I find that when I try to execute "rake db:create", I always get the error
Could not find i18n-0.6.0 in any of the sources
Run `bundle install` to install missing gems.
here is my database.yml:
development:
adapter: mysql
database: attitude
username: attitude
password: ***
host: localhost
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql
database: attitude
username: attitude
password: ***
host: localhost
production:
adapter: mysql
database: attitude
username: attitude
password: ***
host: localhost
i18n shows up in gem list i18n. Bundle show has i18n installed at /usr/lib/ruby/gems/1.9.1/gems/i18n-0.6.0 I've seen some related questions around stackoverflow that seemed to be the result of using sudo bundle install. I tried creating a new rails project and carefully NOT using that command, but to no avail. Do I need to entirely reinstall rails, or is my Ubuntu install ruined, or what?
Run sudo gem uninstall i18n. Then do a bundle install again (without sudo).

I'm trying to use rails 4.2.6 to develop an app. I'm trying to use postgres for database. Server starts fine but when I try loading a page it throws this "No connection pool for ActiveRecord::Base" error.
What could it be?
EDIT
The pg gem wasn't working properly. I had to comment it before starting the server and then uncomment it from my GemFile afterwards. I realized that I was using Ruby 2.3 instead of Ruby 2.0 (as intended). I removed ruby 2.3 and set up everything under ruby 2.0 environment. It's now working properly.
I had read somewhere that there were some issues with the 'pg' gem in newer Rails releases, requiring people to use 'gem install pg --pre' instead for installing the gem. I tried that, but then my app was requiring the 'pg' gem in my GemFile and, well, the problem stated above showed up again.
This is how my database.yml file ended up:
default: &default
adapter: postgresql
encoding: unicode
host: localhost
username: -------
password: -------
pool: 5
development:
<<: *default
database: myDbName
If you are experiencing this error from a rake task, chances are you are not running the :environment task before your task.
Changing:
task :task_name do
end
to:
task task_name: :environment do
end
Should fix the issue.
This issue arises when the server cannot find the corresponding database it depends on to pull data from.
I had same issue from my end, I updated my version of Sqlite3, and it was higher than the version that the current Puma Server version supports.
I simply had to uninstall the Sqlite3 version, and then install the version supported by the current version of Puma Server.
gem uninstall sqlite3
This will uninstall the updated version of Sqlite3, and then you run the code below stating the version supported by your current server.
gem install sqlite3
Or you can as well open your Gemfile, and then include the version for the database that you are using
gem 'sqlite3', '~> 1.3.6'
N/B: The sqlite3 version is the most current version as at the time of writing this answer
And then run
bundle update
to install the version of the database that you specified.
That's all.
I hope this helps.
For PostgreSQL your database.yml file should look something like that:
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: 5
development:
<<: *default
database: your_db_name
Also make sure that you have the gem installed: in your Gemfile:
gem 'pg'
Finally, restart your server.
Hope that helps
Edit: I almost forgot, make sure you have your PostgresSQL running, check this link for download and setup.
Check the database.yml if all settings are ok. If its the first time and you didn't create the database yet use this command to create the database
rake db:create
If the database already exists try reset the db migrations,
rake db:migrate:reset
Hope it'll solve the problem. Go to rails console and try something to check if its working or not.
I had to simply restart the server for the warning to go away.
I've encountered the same problem when I try to access the Model before creating the DataBase.
Make sure you run rake db:migrate at least once.
If you already run migration then check the Database as mentioned in previous answers.
In my case, the config/database.yml was taking variables from the environment:
# ...
test:
<<: *default
database: <%= ENV.fetch("DB_NAME") %>_test
username: <%= ENV.fetch("DB_USER") %>
password: <%= ENV.fetch("DB_PASS") %>
# ...
The error was coming when the new terminal window where I was running the bundle exec rails spec did not have those variables initialized.
Doing,
$ export DB_NAME=mydb
$ export DB_USER=myuser
$ export DB_PASS=mypass
$ bundle exec rails spec
fixed the issue.
I had to restart the server, and make sure you entered username and password. Create development and test databases
when you are running rails db:migrate in data base rows will be created according to your migration files. you can see schema for further info.

Any and all help appreciated.
Doubtful this is the same issue you are having but, posting these details in case it gives a lead. I'm using Windows 10
I had the same error message. To troubleshoot, I tried to do a reinstall of pg with 'gem install pg' but a file was locked.
Found I had a process still using one of the PG files and shut down the process, deleted the entire pg directory found at C:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\pg-0.18.3-x64-mingw32
Reran 'gem install pg' rake db:setup, rake db:create, rake db:migrate and the error was gone.
I am very new to ruby. I am trying to run BBYIDX and followed How to install BBYIDX on Windows?

But rake db:migrate produces this error. I am running ubuntu 12.04, ruby-1.8.7, rails-2.3.11 and gem 1.5.3
How do i solve this?
Thanks in advance.
Did you set a password for your postgres user?
In your config/database.yml you should have your databases set up properly:
development:
adapter: postgresql
encoding: unicode
database: your_app_development # name your development app something
host: localhost
pool: 5
username: your_username
password: your_password # or leave blank if you didn't set a password
test:
adapter: postgresql
encoding: unicode
database: your_app_test
host: localhost
pool: 5
username: your_username
password: your_password
Trying to deploy my rails app to Heroku for the first time, I ran into many problems. The app crashed, and you can look at the logs in the image: http://i.stack.imgur.com/bsx1b.png
Even worse, when I tried to look at my application locally, it failed to work on postgreSQL environment.It worked fine when I went back to use sqLite3 in database.yml. I thought the problem might be that I actually have to install postgreSQL, in addition to adding pg gem and running bundle install.
I went ahead to install PostgreSQL with the one-click installer (Windows 7 64bit). After reboot, a simple rails server or bundle install commands started failing, so I reinstalled the entire ruby & rails.
Now rails server command works fine, and it prompts a different error when I try to look at my app on local environment. So right now I have pgAdmin III and Rails
PG::Error
fe_sendauth: no password supplied
I tried to follow this, but I couldn't find "pg_hba.conf." I guess the answer was based on a different OS.
And now again, the bundler is not working, giving me errors...
Questions:
1) Was I right to install postgreSQL with the one-click installer? Because this caused my ROR to "crash" somehow, and I had to reinstall rails altogether. 2) I think I am going to delete everything related to postgreSQL, reinstall Rails, and start everything from beginning. What are the steps that I have to take? All the references I've looked at do not seem to fit Windows environment.
In my gemfile, I have
gem 'pg'
gem 'thin'
In my database, I have
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
development:
adapter: postgresql
encoding: utf8
database: mangfeel_development
pool: 5
timeout: 5000
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: postgresql
encoding: utf8
database: mangfeel_test
pool: 5
timeout: 5000
production:
adapter: postgresql
encoding: utf8
database: mangfeel_production
pool: 5
timeout: 5000
Errors I'm getting at this moment, after installing PostgreSQL:
c:\ruby\myapp>rails server
C:/Program Files (x86)/ruby-1.9.2/lib/ruby/site_ruby/1.9.1/rubygems.rb:926:in `report_activate_error': Could not find RubyGem railties (>= 0) (Gem::LoadError)

When I run bundle install:

An error occurred while installing json (1.7.5), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.5'` succeeds before bundling.
So I will just remove pgAdminIII, PostgreSQL, Ruby on Rails entirely, and start from scratch.
I thought deploying wasn't going to be this hard, but moving from SQLite3 to PostgreSQL is taking more time and effort than I thought it would. I would really appreciate some help on this problem.
------------------------------------------------------------------------------------------------------------------------
UPDATE: AFTER REINSTALLING EVERYTHING, I'M DOING THE SETUP AGAIN FROM SCRATCH.
I checked that my SQLite3 version app worked fine. So I moved onto setting up postgreSQL. I got the following error when I first set up my postgreSQL. By setting up, I mean editing config/database.yml and installing the gem 'pg' and removing the gem 'sqlite3.' When I tried to connect to localhost:3000, I got the following error:
ActiveRecord::ConnectionNotEstablished
After some research, I found that there could be more steps to setting the db. So I ran the bundle command,
bundle exec rake db:setup
But then in the console, I got the following error when I ran bundle exec rake db:setup.
Couldn't create database for {"adapter"=>"postgresql", "host"=>"localhost", "encoding"=>"utf8", "database"=>"db/myapp_test", "pool"=>5, "timeout"=>5000}
rake aborted!

Question: What did I do wrong, and how do I solve the problem?
If you have error:
PG::Error
fe_sendauth: no password supplied
You have good news, your app can work with PostgreSQL database now. (But you need to configure some thing)
After installing PostgreSQL, you can create new rails app using PostgreSQL by command:
rails new my_app -d postgresql
This is database.yml will be created:
development:
adapter: postgresql
encoding: unicode
database: my_app_development
pool: 5
username: my_app
password:
test:
adapter: postgresql
encoding: unicode
database: my_app_test
pool: 5
username: my_app
password:
production:
adapter: postgresql
encoding: unicode
database: my_app_production
pool: 5
username: my_app
password:
You see that, three database has username and password field, this is account user in Postgresql, three database in database.yaml file will created by this user. So you need to provide username and password for it. Default after install Postgresql, it created a user with username is postgresql and password is postgresql. You can use it.
If you want to use other user, just open pgAdmin III and create new user by right click on Login Roles and choose New login role to create new user with password. Then put that username and password to database.yaml file.
After that, all you need now, is find and open pg_hba.conf file to make some configure for app can work with PostgreSQL. I'm not using Windows for a long time, so I'm not sure where it is, but you can find in folder you installed PostgreSQL. Example, if you install on E:\ partition, maybe you can find it in:
E:\PostgreSQL\version\data
After you found it, open and find a line:
# "local" is for Unix domain socket connections only
local all all ident sameuser
Change it to:
# "local" is for Unix domain socket connections only
local all all md5
Then restart your Postgresql database. To create database for app, run rake db:create or rake db:create:all. Now your app can using PostgreSQL database now, so happy :).
I am not an expert on Rails, but here is one of my YAML files for a recent deployment i did on heroku with POSTGRES
development:
adapter: postgresql
host: localhost
database: dbname_development
production:
adapter: postgresql
host: localhost
database: dbname_production
Seems like you are missing a parameter called host in case of postgres deployment
Steps to Move From SQLite3 to PostgreSQL on Windows, for an Existing Rails App to Deploy To Heroku:
In your Gemfile, find gem 'sqlite3' and change it to gem 'pg'. Run bundle install.
Download Postgres from here. Choose the one-click installer and select your OS environment (32 or 64 bit). During installation, do NOT choose to install any extra software it recommends you to install. It will possibly mess up your existing Rails and you will have to reinstall Rails.
Now go to config/database.yml, and change it to the following format. The current one is set for SQLite3 and is missing some fields necessary for PostgreSQL.
development:
adapter: postgresql
encoding: unicode
database: my_app_development
pool: 5
username: my_app
password:
test:
adapter: postgresql
encoding: unicode
database: my_app_test
pool: 5
username: my_app
password:
production:
adapter: postgresql
encoding: unicode
database: my_app_production
pool: 5
username: my_app
password:
The adapter is different, and there are fields for username and password. The default username and password is postgresql, but if it doesn't work (it didn't work for me), then go to your pgAdmin, create a new login role to make another username/password (check the option to make it a super user) and use that.
4, At this point, you can create a new app by running
rails new my_app -d postgresql
Run your local server, and try connecting to localhost:3000 to see if the welcome page is showing.
5, If everything is working fine, then all you need to do is create a new PostgreSQL database, and migrate your existing models to it. Run
rake db:create:all
rake db:migrate
Done! Now check if your existing app is working fine locally, and try deploying your app to Heroku.
I did the following after installing Postgres locally:
gem install postgres-pr
I changed the database.yml:
development:
adapter: postgresql
encoding: unicode
database: typhoon_development
pool: 5
Then, when I did a rake db:create got:
uninitialized constant PostgresPR::Connection::UNIXSocket
Couldn't create database for {"encoding"=>"unicode", "adapter"=>"postgresql", "database"=>"typhoon_development", "p
ool"=>5}
I'm doing it locally to mimic the heroku environment.
Try to provide hostname and port number in the config.
I used a different gem
