如何安装"readline"并使其正常工作？
更新:我可能在尝试在其他地方找到解决方案时弄乱了我的系统.我从零开始,安装Ruby 1.9.3顺利安装.现在试着让ree-1.8.7和...一起玩得很好......
我正在尝试使用RVM在Kubuntu上安装Ruby 1.9.3(我相信11.10).到目前为止,我一直有很多关于Readline的问题,但除此之外我找到了答案.
我用这种方式安装了Ruby 1.9.3:
rvm install 1.9.3
# Install of ruby-1.9.3-p0 - #complete

~/.rvm/src/ruby-1.9.3-p0/ext/readline $ ../../ruby extconf.rb --with-editline-dir="/usr" --with-readline-dir="/usr"
# any other way of doing this resulted in simply readline not being loaded when trying to start the console
# I have libreadline6 and libreadline6-dev installed (and all the packages requested in `rvm requirements`
make install
# compiling readline.c
# linking shared-object readline.so
# /usr/bin/install -c -m 0755 readline.so /home/mbillard/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/x86_64-linux
# installing default readline libraries
