node.js 和 node 有什么区别? [英] What are the differences between node.js and node?

问题描述

我已经在我的机器上安装了 node.js (linux mint 15)，当我运行 node example.js 时，它说:

I've installed node.js in my machine (linux mint 15), when I run node example.js, it says:

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有什么区别呢?我之前安装了 node.js 和 node，但是当我运行 node example.js 时，Web 服务器根本没有启动.所以我删除了节点并保留了 node.js.

So what are the differences between node and nodejs? I had both node.js and node installed previously, but when I run node example.js, the web server doesn't start at all. So I deleted node and kept node.js.

推荐答案

包节点与node.js无关.

The package node is not related to node.js.

nodejs 是您想要的，但是为了与使用 #!/usr/bin/env node 的脚本兼容，将命令称为 node 可以说更好.

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.

您可以只在路径中创建一个符号链接:

You can either just create a symlink in your path:

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

或者你可以安装 nvm 然后用它来安装最新版本的node.js:

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

nvm install stable

我更喜欢 nvm 方法，因为它允许您sudo apt-get remove nodejs，然后管理您自己使用的节点版本.您还可以安装多个版本的 node.js，并使用 nvm use 在它们之间轻松切换.

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.

我还喜欢在 .bashrc 的底部添加一行，例如:nvm use stable >/dev/null.这将自动使用您安装的最新版本.

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.

要将您的节点版本更新到最新的稳定版:nvm install stable.每次执行此操作时，如果您想继续使用它们，您都需要安装已全局安装的任何 npm 包.

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.

要切换到旧版本，只需运行 nvm use ，或者，如果您尚未安装旧版本:nvm install 代码>.

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>.
