Ubuntu rvm 设置问题 [英] Ubuntu rvm setup issue

问题描述

我按照以下教程进行操作:

I followed this tutorial below:

https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-房车

这对我来说非常有效；但是，我有一个小问题?

This worked perfectly for me; however, I have one small problem?

每次我打开一个新终端时，我都必须运行这个命令才能让 rails 工作:

Each time I open a new terminal I have to run this command in order for rails to work:

源代码 ~/.rvm/scripts/rvm

source ~/.rvm/scripts/rvm

是什么问题，为什么rvm无法识别

What is the problem and why is rvm not recognized

这是我打开新终端并验证 rails 后看到的:

This is what I see after I open a new terminal and verify rails:

robert@rob:~$ rails -v当前未安装程序rails".您可以通过键入以下内容来安装它:sudo apt-get 安装导轨

robert@rob:~$ rails -v The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails

谢谢

推荐答案

强烈推荐大家使用官网安装RVM:https://rvm.io/rvm/install

I highly recommend you to use the official website to install RVM: https://rvm.io/rvm/install

您的问题是当您打开新终端时未加载 RVM，这就是您必须在终端的每个实例中手动添加源的原因.

Your problem is that RVM is not loaded when you open a new terminal, this is why you have to manually add the source at each instance of the Terminal.

要解决此问题，请运行以下命令行:(如果使用 login-shell)

To solve this, run this command line: (if using login-shell)

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile

或者这个(如果使用非登录shell):

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bashrc

这将添加到 RVM 的路径以在每个终端实例化时加载(完成此操作后关闭并重新打开终端).

This will add the path to RVM to load at each Terminal instanciation (close & re-open a terminal after you did this).
