Js 和 node 之间有什么区别？

我已经在我的机器(linux mint15)中安装了 node.js，当我运行 node example.js时，它会显示:

The program 'node' can be found in the following packages:
* node
* nodejs-legacy
Try: sudo apt-get install <selected package>

那么 node 和 nodejs 之间的区别是什么呢？我以前安装了 node.js 和 node，但是当我运行 node example.js时，Web 服务器根本不会启动。所以我删除了 node 并保留了 node.js。

The package node is not related to node.js.

nodejs is what you want, however it is arguably better to have the command be called node for compatibility with scripts that use #!/usr/bin/env node.

You can either just create a symlink in your path:

sudo ln -s `which nodejs` /usr/local/bin/node

Or you could install nvm and then use it to install the latest version of node.js:

nvm install stable

I prefer the nvm method, as it allows you to sudo apt-get remove nodejs, and then manage which version of node you're using yourself. You can also have multiple versions of node.js installed and use nvm use <version> to easily switch between them.

I also like to add a line to the bottom my .bashrc like: nvm use stable > /dev/null. That will automatically use the latest version you have installed.

To update your node version to the latest stable: nvm install stable. Every time you do this you will need to install any npm packages that you had installed globally if you want to continue using them.

To switch to an old version just run nvm use <version>, or, if you don't have the old version installed already: nvm install <version>.

This answer is just to tell you the difference between node and nodejs packages on Debian OS.

node

nodejs

  • Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

There is a simple answer.

  1. Node.JS is the script/code
  2. Node compiles and runs the Node.JS
