使用 RVM，但无法设置当前的 Ruby 版本 (Ubuntu 11.10) [英] Using RVM, but can't set current Ruby version (Ubuntu 11.10)
问题描述
我最近在全新安装的 Ubuntu 11.10 上安装了 RVM，但不知道如何开始使用特定的 ruby 版本.
I have recently installed RVM on a fresh install of Ubuntu 11.10 and can not work out how to start using a particular ruby version.
我已经安装了 Ruby 1.8.7 和 1.9.2，它们都很好地显示在列表中:
I have installed Ruby 1.8.7 and 1.9.2, and they show up in the list fine:
$ rvm list
rvm rubies
ruby-1.8.7-p352 [ i386 ]
ruby-1.9.2-p290 [ i386 ]
当我尝试使用use"命令时，一切似乎都很好:
When I try to use the "use" command, everything seems fine:
$ rvm use 1.9.2
Using /usr/share/ruby-rvm/gems/ruby-1.9.2-p290
Running /usr/share/ruby-rvm/hooks/after_use
但是当我测试当前的 ruby 版本时，我得到了当您根本没有 RVM 时通常会得到的 Ubuntu 11.10 消息:
But then when I test the current ruby version, I get the usual Ubuntu 11.10 message you get when you don't have RVM at all:
$ ruby -v
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
我做错了什么?我是否错过了 RVM 安装中的某个步骤?
What am I doing wrong? Did I miss out a step in the RVM installation or something?
编辑*
对一些评论的回答:
$ which ruby
#returns nothing at all.
$ which rvm
/usr/bin/rvm
$ rvm -v
rvm 1.6.9 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
$ echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
推荐答案
RVM 1.6.9 现在已经很老了.你是通过一些包管理器安装的吗?如果是这样，摆脱它并在你的 bash shell 中运行以下命令:
RVM 1.6.9 is very old now. Did you install it through some package manager? If so, get rid of it and run the following in your bash shell:
curl -L https://get.rvm.io |bash -s 稳定
然后，放置 [[ -s "$HOME/.rvm/scripts/rvm" ]] &&. OR ~/.profile 中的$HOME/.rvm/scripts/rvm"~/.bash_profile OR ~/.bashrc>
Then, place [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" in ~/.profile OR ~/.bash_profile OR ~/.bashrc
然后您应该能够运行 type rvm |head -n 1 并且它应该说rvm 是一个函数".
You should then be able to run type rvm | head -n 1 and it should say "rvm is a function".
然后您应该能够安装红宝石并使用其中之一.请务必使用 --default 使该 Ruby 保持默认值，即使在您结束终端会话后也是如此.例如.rvm 使用 ruby-1.9.2-p290 --default
Then you should be able to install rubies and use one of them. Be sure to use --default for that Ruby to remain the default even after you end your terminal session. E.g. rvm use ruby-1.9.2-p290 --default
