sudo gem install rails - 这不给我一个rails命令的bash [英] sudo gem install rails- this doesn't give me a rails command for bash

问题描述

我在Ubuntu。我输入 sudo gem install rails 。这工作正常，安装轨道和其他7个宝石罚款。但是 $ rails blog 正在说：

 程序'rails'目前没有安装。您可以通过键入以下方式来安装它：
 sudo apt-get install rails 
  

解决方案

你是如何安装rubygems，作为管理员或用户？如果您以用户身份安装它，则可能没有您的路径中的bin目录。

如果我是你（假设你的家庭文件夹中安装了rubygems）我会垃圾的安装目录（不知道它默认的地方，也许〜/ ruby​​gems？或〜/ .rubygems？），然后运行setup.rb从rubygems的tarball作为管理员（通过sudo）我已经做到了这至少一个ubuntu上有十几次，还没有遇到你遇到的问题。

如果不是这样，你可以链接到你的博客文章以下？

I'm on Ubuntu. I type in sudo gem install rails. This works fine, installs railes and 7 other gems fine. Yet $ rails blog is saying this:

The program 'rails' is currently not installed.  You can install it by typing:
sudo apt-get install rails

解决方案

how did you install rubygems, as an admin, or as a user? if you installed it as a user, it may not have the bin directory in your path.

If I were you, (assuming you installed rubygems into your home folder), I would trash that installation dir (not sure where it defaults to, maybe ~/rubygems? or ~/.rubygems?), then run setup.rb from the rubygems tarball as admin (through sudo) I've done this at least a dozen times on ubuntu, and haven't run into the issue you are hitting.

If that isn't the case, could you please link to the blog post you were following?
