RVM 不是一个函数，选择带有“rvm use ...”的红宝石将不起作用

Question

我正在尝试按照此处的说明安装Discourse，但命令

# Use installed ruby as default
rvm use 2.0.0 --default 

结果如下：

discourse@ubuntu:~$ rvm use 2.0.0 --default

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

我明白那个

For RVM to work properly, you have to set the 'Run command as login shell' checkbox on the Title and Command tab inside of gnome-terminal's Settings page.

如此处所述，但我无法访问 GUI，因为我正在通过 ssh 安装到 ubuntu 服务器。如何在 gnome 中更改该设置？

Answer 1

这将起作用，手动将这些行添加到您的 ~/.bashrc 文件中

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

Answer 2

跑步：

rvm get stable --auto-dotfiles

确保您阅读了所有输出 - rvm 为您打印信息和警告，您可以修复任何无法自动修复的问题
