file 'lib' not found

and if i run rake db:migrate

it says:

  ............
    rake aborted!

stack level too deep

---

try this :

sudo gem install rails --no-ri --no-rdoc

and if you want to install RDoc use :

sudo gem install rdoc-data
sudo rdoc-data --install
sudo gem rdoc --all --overwrite

if that doesnt work try this :

sudo apt-get install ruby-dev build-essential

---

Note, the following also seems to work on Windows 7. (omit the "sudo")

gem install rails --no-ri --no-rdoc

---

I got similar with gem install rails (Ubuntu 12.04, with RVM)

Installing ri documentation for rails-3.2.13...
file 'lib' not found
Installing RDoc documentation for rails-3.2.13...
file 'lib' not found

installing RDoc and then reinstalling rails solved the problem for me. So:

gem install rdoc
gem install rails

---

This is still happening on rails-3.2.3.

What appears to work is to install rdoc first. So, with a freshly installed ruby, do:

gem install rdoc gem install rails

---

It seems like there are some issues with ree and ruby 1.8.. If you have rvm try use ruby 1.9.2 or any 1.9.

then

gem install rails will work
