如何在 Ubuntu 11.10 上使用 RVM 在 IRB 中获得 Readline 支持 [英] How to get Readline support in IRB using RVM on Ubuntu 11.10
本文介绍了如何在 Ubuntu 11.10 上使用 RVM 在 IRB 中获得 Readline 支持的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经尝试了所有我能想到的方法来让它工作，但无济于事，所以我在这里请求有关如何调试的建议.
I have tried everything I can think of to get this to work, to no avail so here I am requesting suggestions on how to debug.
首先，运行 Ubuntu 11.10
Firstly, runnning Ubuntu 11.10
安装的rvm:
$ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
使用 apt-get 安装 readline:
Installed readline using apt-get:
$ sudo apt-get install libreadline-dev
检查readline安装:
Check for readline install:
$ dpkg --get-selections | grep readline
lib64readline-gplv2-dev install
lib64readline5 install
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install
安装 ruby，支持 readline?
Install ruby, with readline support?
$ rvm install 1.9.2 --with-readline-dir=/usr
这是rvm版本:
$ rvm --version
rvm 1.9.2 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
让我们试试 ruby shell:
Lets try the ruby shell:
$ irb
1.9.2 :001 > puts "add history"
add history
=> nil
1.9.2 :002 > ^[[A^[[A^[[A^[[A^[[A <------ PRESS UP ARROW DOES THIS
不，好吧，如果它不适用于 ubuntu 的 readline 版本???让我们尝试使用 rvm 自己的 readline 版本:
No, ok so if its not going to work with ubuntu's readline version??? lets try with rvm's own version of readline:
$ rvm pkg install readline

Readline was unable to be required, if you need completion or history install readline then reinstall the ruby.
You may follow 'rvm notes' for dependencies and/or read the docs page https://rvm.beginrescueend.com/packages/readline/ . Be sure you 'rvm remove X ; rvm install X' to re-compile your ruby with readline support after obtaining the readline libraries.

总而言之，如果有一些亮点可以建议我如何调试和解决这种情况，我将不胜感激.
So in conclusion, I would be exceptionally grateful if some bright spark could suggest how I can debug this situation and resolve.
ps - 是的，我已经谷歌"了这个问题……
ps - Yes I have "Google" this problem to death....
推荐答案
好的，所以这看起来很明显，当你知道答案的时候总是这样:
Ok, so this might seem pretty obvious, well it always is when you know the answer:
我放弃了使用 RVM，转而使用 rbenv - 我很高兴我做到了！
I gave up using RVM, and switched to rbenv - which I'm very pleased I did!
sudo apt-get install libreadline-gplv2-dev
CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline --with-openssl-dir=/usr/local" rbenv-install 1.9.2-p290
这安装没有错误 - 我仍然不相信我需要 gplv2 包，因为我已经安装了 libreadline6-dev.然而，这仍然没有解决我的问题.它确实从等式中删除了 RVM，并向我表明尽管我尽了最大的努力 IRB shell 拒绝使用 readline.
This installed without error - and I'm still not convinced I need the gplv2 package as I've got libreadline6-dev installed. However that STILL didn't resolve my problem. It did remove RVM from the equation, and show me that despite my best efforts the IRB shell was refusing to use readline.
答案来自阅读这篇很棒的指南:
The answer came from reading through this great guide:
在我的 ~/.irbrc 文件中，我发现:
Inside my ~/.irbrc file I found:
IRB.conf[:USE_READLINE] = false
快速更新:
IRB.conf[:USE_READLINE] = true
我正在用煤气做饭！！
感谢所有出色的回答和建议，我非常感谢您的时间.
Thanks for all the great answers and suggestion, I do appreciate your time.
这篇关于如何在 Ubuntu 11.10 上使用 RVM 在 IRB 中获得 Readline 支持的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
