no such file to load — readline (LoadError) when running script/console
Ruby on Rails, Ubuntu/Linux Add commentsIf you get
Loading development environment (Rails 2.3.2)
/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require’: no such file to load — readline (LoadError)
from /usr/local/lib/ruby/1.8/irb/completion.rb:10

when running script/console, you might be missing some libraries after you’ve installed Ruby from source. So you might try (Ubuntu, Debian):
sudo apt-get install libncurses5-dev
sudo apt-get install libreadline5-dev
Then cd to the folder with your unpacked Ruby sources, subfolder ext/readline:
cd /usr/src/ruby-1.8.7-p72/ext/readline
ruby extconf.rb
make
sudo make install
There is no need to recompile Ruby. If you get any of these:
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
you’re still missing libraries so re-check if the apt-get commands above completed without errors. Hope it helps.

Thank you for the hint! Worked fine with my self compiled rails on Debian Lenny.

It’s all fun and games until someone compiles from source. Thank you for the tip!

Thanks for the tip. Barring this, you can also install the “pure ruby readline”
