Ruby 1.9.2 and Rails 3 Cannot Open Rails Console

Ruby 1.9.2 and Rails 3 cannot open rails console

Apparently ubuntu and ruby don't always catch dependencies like they should.

From the first google hit (yeah, I clicked on this stack-overflow in place #2 before checking out the first result.)

Navigate to the Ruby source and enter:

sudo apt-get install libreadline5-dev
cd ext/readline
ruby extconf.rb
make
sudo make install

So, if you're on another distro, make sure you install readline somehow (source/package), then run make/install on extconf from the source. I tried what gkaykck suggested of course but got this without readline already on my system.

$ ruby extconf.rb
checking for tgetnum() in -lncurses... no
checking for tgetnum() in -ltermcap... no
checking for tgetnum() in -lcurses... no
checking for readline/readline.h... no
checking for editline/readline.h... no

Cannot launch Rails console

Try again with a normal user, after installing RVM as a normal user.

Installing RVM as root is a pain as far as I experienced, I particularly had paths issues.

Error starting rails server 3 with Ruby 1.9.3 and Rails 3.2.13

Either you've misspelled a resources declaration in your config/routes.rb file or a gem you're using has during a generator. Do a search for resoures in said file and replace it with resources.

That's what this error is referring to:

undefined method 'resoures'

getting error messsage when starting rails console:

You need an environment called "development," not "Listings_development." Rename your environment and try starting the console again.

Console not loading server

rails console isn't supposed to run the server. It's the console, and you just mess with it, typing stuff inside and getting replies from it via on-screen text messages.

Everything's working fine, you may continue venturing into the mysterious and rewarding world of Ruby on Rails development.

Rails console not working with redgreen gem

Specifying in my Gemfile:

gem 'test-unit', '1.2.3'

...seems to work for me with 1.9.3 and Rails 3.2.8. It would, however, be nice to use this with a more recent version of test-unit (looks like 2.5.2 is the latest right now)...

Rails- Cannot Load Error

You need at least Ruby version 1.9.3 or above to use Rails 4 I believe.
