将Node.js设置为$ PATH [英] Set Node.js to $PATH

问题描述

我正在研究RoR，并将此虚拟机设置为部署 RoR，并且卡在Node.js安装中。

I am studying RoR and I am setting this virtual machine to "deploy" RoR and I got stuck in the Node.js installation.

我正在使用Ubuntu 12.04。我遵循了本指南的这一步骤：

I am using Ubuntu 12.04 and I followed this step of this guide:

http：// railsapps.github.com/installing-rails.html

自Rails 3.1以来，需要JavaScript运行时来进行开发Ubuntu Linux（Mac OS X或Windows不需要）。对于在Linux Ubuntu上进行
开发，最好安装Node.js
服务器端JavaScript环境：

Since Rails 3.1, a JavaScript runtime has been needed for development on Ubuntu Linux (it is not needed for Mac OS X or Windows). For development on Linux Ubuntu, it is best to install the Node.js server-side JavaScript environment:

$ sudo apt-get install nodejs

并将其设置在$ PATH中。

and set it in your $PATH.

设置为我的$ PATH是什么意思？

What does it mean, "set to my $PATH"?

我上次在Google上一直在搜索它几个小时，所有解决方案都不一样，针对不同的问题，对此我没有简单的答案。

I've been searching for it on google in the last couple of hours and all solutions are different, for different problems and I get no simple answer for that. Can you give a little light here?

谢谢！

推荐答案

您不必担心， apt-get install 命令将为您完成此操作。
它将nodejs进程的路径（通常 / usr / bin / node ）添加到全局$ PATH变量中。这样可以确保当您在终端中键入 node 时，它将启动nodejs进程。

You don't have to worry about that, the apt-get install command will do that for you. It adds the path to the nodejs process (usually /usr/bin/node) to the global $PATH variable. This ensures that when you type node in your terminal it will start the nodejs process.

如果由于某种奇怪的原因而无法启动它，则必须将节点安装的路径手动添加到$ PATH中。您可以通过编辑〜/ .bashrc 文件并添加：

If for some weird reason you cannot start it, you'll have to manually add the path to your node installation to the $PATH. You can do this by editing your ~/.bashrc file and adding:

PATH=/usr/bin/node:$PATH
