rails console出错
CentOS下：项目下rails console出错：
rails c/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:10from /usr/local/lib/ruby/gems/1.8/gems/railties-3.0.3/lib/rails/commands/console.rb:3:in `require'from /usr/local/lib/ruby/gems/1.8/gems/railties-3.0.3/lib/rails/commands/console.rb:3from /usr/local/lib/ruby/gems/1.8/gems/railties-3.0.3/lib/rails/commands.rb:20:in `require'from /usr/local/lib/ruby/gems/1.8/gems/railties-3.0.3/lib/rails/commands.rb:20from script/rails:6:in `require'from script/rails:6
到ruby源文件目录下
$ cd readline
$ ruby extconf.rb
出错：
checking for tgetnum() in -lncurses... nochecking for tgetnum() in -ltermcap... nochecking for tgetnum() in -lcurses... nochecking for readline/readline.h... nochecking for editline/readline.h... no
$ yum install readline-devel.i386
$ yum install ncurses-devel.i386
后重新
$ ruby extconf.rb
$ make && make install
ok,重新rails console也ok
