ubuntu 11.10 rails 3.1.3 控制台输入rails c 一直报

/home/gsm/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/irb/completion.rb:9:in `require': cannot load such file -- readline (LoadError)

Bash代码

sudo apt-get install libncurses5-dev libreadline5-dev 

但是实践发现libreadline5-dev已经废弃了 “现在没有可用的软件包 libreadline5-dev,但是它被其它的软件包引用了。 这可能意味着这个缺失的软件包可能已被废弃, 或者只能在其他发布源中找到 可是下列软件包取代了它: libreadline-gplv2-dev:i386 lib64readline-gplv2-dev:i386 libreadline-gplv2-dev E: 软件包 libreadline5-dev 没有可供安装的候选者”

参考步骤2 - 用 RVM 安装 Ruby 环境

$ rvm pkg install readline
$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

仍然无法解决 有谁知道怎么解决啊???

我记得以前用Ubuntu的时候,通过安装 ruby-full 来安装系统ruby以及相关的所有依赖包,你试试看,然后重新编译一次 ruby?

sudo apt-get install ruby-full

Google了一下,ruby-full 包含了对 libreadline-ruby 的依赖,可能会解决你的问题。 http://packages.ubuntu.com/hardy/ruby-full

rvm安装完后,没有仔细看rvm的info. 里面有ubuntu下build ruby需要的所有依赖包.一条命令就安装完毕了.

一般这种情况下,我一般的解决办法是 uninstall,clean,安装依赖包 然后再install一下. 一定要clean.

刚执行了

sudo apt-get install ruby-full
cd ~/.rvm/src/ruby-1.9.3-p0/ext/readline
ruby extconf.rb
出现“ checking for tgetnum() in -lncurses... yes
checking for readline/readline.h... yes
checking for readline/history.h... yes
checking for readline() in -lreadline... no
checking for readline() in -ledit... no
checking for editline/readline.h... no”
make install

出现 “ make: 没有什么可以做的为 `install'。”

rails c的问题仍没解决 等待中。。。。。

前几天开始使用rvm后遇到过你这个问题,好在记录下来了,分享一下:

rvm pkg install openssl (older format - rvm package install openssl)
rvm pkg install iconv (older format - rvm package install iconv)
rvm pkg install readline(rails console缺少的lib)
rvm remove 1.9.3
rvm install 1.9.3 -C --with-openssl-dir=\$HOME/.rvm/usr,--with-iconv-dir=\$HOME/.rvm/usr, --with-readline-6.2-dir=\$HOME/.rvm/usr 
rvm 1.9.3 --default

5废掉了用 6

$ sudo apt-get install libreadline6-dev 

感谢6楼的朋友 问题顺利解决了呵呵

不客气..我是菜鸟啊..互相学习!!哈哈..

用6楼方法装readline 和 iconv 报错,不能rails console http://ruby-china.org/topics/996 同问

rvm requierment

源码包里面有各种ext lib,编译时没装过的话,apt-get install xxx后,进入ruby源码包找到对应的xxx,然后ruby mkconfig,make make install就行,不用重编译ruby的

sudo apt-get install libreadline6 libreadline6-dev 再到ruby源码里安装readline就可以了。 我也遇到过。

rvm pkg install readline之后重装ruby

#3楼 @Saito 强调一下saito的经验,以前我也老被这种事郁闷,不过从某个版本开始,rvm会提示你要安装的c库了,提示很清晰,直接列出你要在ubuntu上运行的命令,很有参考价值,所以强烈建议认真看看rvm输出的各种信息

Ubuntu的库更新不够快,Arch装新版一点压力都没有

17楼 +1

同样遇到这个问题了,可以通过如下方式解决: 先安装readline,命令如下: apt-get install libreadline6-dev 再进入到ruby源码中,重新编译readline,命令如下:

cd ~/.rvm/src/ruby-1.9.3-p0/ext/readline
ruby extconf.rb  
make  
sudo make install  

就可以了

15楼正解

fedora安装也没遇到压力。

@superbatironmans5 rvm pkg install autoconf # 可能需要 sudo apt-get remove autoconf; sudo apt-get purge autoconf rvm pkg install readline # 可能需要 rvm pkg install ncurses rvm reinstall 1.9.3 --with-readline-dir=$RVM_HOME/usr # 可能需要 --with-ncurses-dir=$RVM_HOME/usr rvm use 1.9.3 --default 我是大概这么个过程。 用 UBUNTU 10.04 没遇这问题

#19楼 @xiongbo 多谢,顺利解决了!
