安装Rails，但rails命令说它没有安装 [英] Installed Rails but the rails command says it's not installed

问题描述

我使用Ubuntu 9.10 Karmic Koala和Ruby 1.9.1。

我使用安装Rails sudo gem install rails


当我在终端中键入 rails 时，它说。

程序'rails'目前未安装。你可以通过键入以下命令来安装它：
sudo apt-get install rails
rails：command not found

我可以找到rake，它位于rake1 .9.1，但Rails无处可查，有人能指点我的方向吗？

编辑：ruby的路径不是问题，问题出在哪里是铁轨吗？我该如何执行它？ Rails只是不起作用，可执行文件的生命在哪里？

正如其他人所说，这很可能是一个PATH变量问题在您的bashrc / bash_profile文件中。

您可以通过键入 echo $ PATH 来获取当前的PATH变量。您可以了解如何更改PATH。

$ c>

I'm using Ubuntu 9.10 Karmic Koala and Ruby 1.9.1.

I installed Rails using sudo gem install rails, which installed all the libraries for me.

When I type rails in the terminal it says.

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

I can find rake, which is under rake1.9.1, but Rails is nowhere to be found, can someone point me in the right direction?

Edit: path to ruby isn't the problem, the problem is where is rails? how do I execute it? rails just doesn't work, where does the exectuable lives?

解决方案

As others say, this may very well be a PATH variable issue on your bashrc/bash_profile file.

You can learn how to change PATH..

You can get the current PATH variable by typing echo $PATH
