Question

我不明白为什么在rvm命令之后我仍然使用ruby 1.8.7。我按照rvm的安装说明进行操作，一切似乎都没问题 - 我在哪里开始解决这个问题？

andrew@unifex:~$ rvm use 1.9.2 --default
Using /home/andrew/.rvm/gems/ruby-1.9.2-p290
andrew@unifex:~$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]
andrew@unifex:~$

andrew@unifex:~$ rvm info

ruby-1.9.2-p290:

我遇到了这个问题。这取决于你的$ PATH不正确 - 在rvm有机会做它之前找到/ usr / bin / ruby。

在你的〜/ .bash_profile中（如在/Users/andrew/.bash_profile中），确保你在文件的底部显示这一行：

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

然后打开一个新的shell

rvm reload
rvm use 1.9.2 --default
ruby -v

您现在应该显示正确的版本。

rvm使用1.9.2让我使用ruby 1.8.7
