问题描述
使用 https://rvm.beginrescueend.com/rvm/install/ 安装 ruby (ruby 1.9.2p290) &gems(没问题),然后通过 gem install rails
安装 rails(Rails 3.2.0).但是,当我尝试在我的/user 目录以外的另一个目录中创建一个 rails 应用程序(或发出 rails -v
)时,我得到当前未安装程序‘rails’.您可以通过以下方式安装它键入:sudo apt-get install rails"我还注意到,如果我发出 ruby -v 我得到当前未安装程序‘ruby’.您可以通过键入:sudo apt-get install ruby".
Used https://rvm.beginrescueend.com/rvm/install/ to install ruby (ruby 1.9.2p290) & gems (no problems), then installed rails via
gem install rails
(Rails 3.2.0). But when I try and create a rails app (or issue rails -v
) in another directory other than my /user directory I get "The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails" I also noticed that if I issue ruby -v I get "The program 'ruby' is currently not installed. You can install it by typing: sudo apt-get install ruby
".
显然,这是一个 $PATH 问题,但它已经很长时间,因为我不得不这样做,以至于我完全忘记了如何解决这个问题.我认为这是一个简单的解决方法,但目前我对如何解决这个问题感到有点迟钝.
Obviously, this is a $PATH issue but it's been so long since I've had to do this that I've totally forgotten how to fix the issue. I'm thinking it's a simple fix but I'm feeling borderline retarded at the moment on how to solve this.
再说一次,据我所知,只要我在我的/user 目录中创建一个应用程序或发出命令版本命令......等等,一切顺利.
Again, as far as I can tell, as long as I create an app or issue command version commands...etc..in my /user directory all goes well.
一些可能也有帮助的事情:
A few things that might help as well:
which rails
给了我:/home/j3/.rvm/gems/ruby-1.9.2-p290/bin/rails
which rails
gives me: /home/j3/.rvm/gems/ruby-1.9.2-p290/bin/rails
which ruby
给了我:/home/j3/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
which ruby
gives me: /home/j3/.rvm/rubies/ruby-1.9.2-p290/bin/ruby

推荐答案
似乎您的 rvm 没有正确添加到 PATH(或已损坏).
Seems like your rvm has not been added to PATH properly (or it was broken).
将此行添加到您的配置文件设置(.bashrc 或 .bash_profile)
Add this line to your profile settings (.bashrc or .bash_profile)
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
并获取文件:
source ~/.bashrc
或
source ~/.bash_profile
您似乎错误地将 echo 行添加到 .bashrc 中,应该在终端中执行.
You seem to have added the echo line to .bashrc by mistake, it should be executed in terminal.
