找不到Ubuntu RVM Rails bash命令

我刚刚安装了Ubuntu,之后我想用ruby和rails 3.1安装RVM。

安装进展良好,但是当我想创build一个rails应用程序,它找不到rails命令。

我知道我可以创build一个别名,但是当rvm改变它的gemset时,别名path会错误的吗?

这是我的.bashrc文件(/home/user/.bashrc):

# ~/.bashrc: executed by bash(1) for non-login shells. # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc) # for examples # If not running interactively, don't do anything [ -z "$PS1" ] && return # don't put duplicate lines in the history.

所以,我真的不知道如何让这个工作…

帮助表示赞赏!

你需要

通过添加一行来添加rvm到你的.bashrc

 [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 

这将允许您在启动新的bash会话时加载rvm

当你想要一个新的导轨时创建一个新的Gemset。

工作流程应该像这样工作

 $ mkdir new_rails_app $ cd new_rails_app $ vim .rvmrc # edit the .rvmrc to use the correct Gemset Something like rvm use ruby-1.9.2-p180@new_rails_app --create #save and exit vim $ rvm rvmrc load # you should see a prompt that your Gemset was loaded $ gem install rails $ rails new . 

您现在有一个使用rvm的新应用程序的工作栏目录。 还有其他一些小技巧,如自动加载你的rvmrc的,但我只是为了“最简单”的路线离开了。

我遇到了“ command not found:rails ”的问题,但是我在shell提示符下使用了oh-my-zsh ,我通过复制这个行来解决这个问题

 PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session. 

从文件〜/ .bashrc〜/ .zshrc ,它运作良好。 希望能给你一些帮助。
