使用 RVM 安装了 Ruby 1.9.3,但命令行不显示 ruby -v [英] Installed Ruby 1.9.3 with RVM but command line doesn't show ruby -v
问题描述
这是控制台输出:
sergio@sergio-VirtualBox:~$ rvm list
rvm rubies
ruby-1.9.3 [ i386 ]
sergio@sergio-VirtualBox:~$ rvm use 1.9.3
Using /usr/share/ruby-rvm/gems/ruby-1.9.3
sergio@sergio-VirtualBox:~$ ruby -v
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
那是怎么回事?我需要重新启动我的机器吗?或者它应该立即起作用?我正在使用 Ubuntu 11.10,感谢您的帮助.
So what's going on? Do I need to reboot my machine? Or should it work right off the bat? I'm using Ubuntu 11.10, any help is appreciated.
推荐答案
您的 RVM 版本已损坏.Ubuntu 对 RVM 做了一些会产生大量错误的事情,目前唯一安全的修复方法是:
You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:
sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh
打开新终端并验证旧 RVM 设置中的环境是否干净(应该没有输出):
open new terminal and validate environment is clean from old RVM settings (should be no output):
env | grep rvm
如果有输出,请尝试打开新终端,如果没有帮助,则重新启动计算机.
if there was output, try to open new terminal, if it does not help then restart your computer.
curl -L https://get.rvm.io |
bash -s stable --ruby --autolibs=enable --auto-dotfiles
