问题描述

我已经安装了 ruby​​ 1.9.3现在当我想在一个项目上启动rails server"时，我收到了这个错误:/usr/bin/env: ruby​​1.8: 没有那个文件或目录

I have installed ruby 1.9.3 and now when I want to start "rails server" on a project I get this error: /usr/bin/env: ruby1.8: No such file or directory

我在一些帖子中看到我必须更改某些内容的 PATH，但我不知道该怎么做.我是 Linux 新手.

I saw in some posts that I have to change PATH of something but I don't know how to do that. I am new in linux.

echo $PATH:
~/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin‌​:/sbin:/bin:/usr/games:/home/mordehai/.rvm/bin:/home/mordehai/.rvm/bin 

我用sudo apt-get install ruby​​1.9.3 和 rvm"安装了几次

I installed few times with "sudo apt-get install ruby1.9.3, and with rvm

推荐答案

我在较旧的 Debian 安装上遇到了这个问题，该安装至少经历了一个 apt-get dist-upgrade.

I had this issue on an older Debian install that's gone through at least one apt-get dist-upgrade.

四处寻找罪魁祸首，很快就发现升级系统 ruby​​ 后留下了一堆垃圾.

Looking around for the culprit it quickly became apparent that there was a bunch of cruft left over after an upgrade of the system ruby.

grep -r "ruby1.8" /usr/bin/*
/usr/bin/erubis:#!/usr/bin/ruby1.8
/usr/bin/rackup:#!/usr/bin/ruby1.8
/usr/bin/rails:#!/usr/bin/ruby1.8
...
/usr/bin/X11/redcloth:#!/usr/bin/ruby1.8

引用太多，无法修复 &我不想维护所有这些文件，因此让 ruby​​1.8 可用于任何需要它的脚本似乎更容易.

Too many references to fix & I don't want to maintain all these files, so It seemed easier to make ruby1.8 available to any scripts that were expecting it.

修复就像运行一样简单

ln -s /usr/bin/ruby /usr/bin/ruby1.8
