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

问题描述

我已经在计算机上安装了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?我之前已经安装了node.js和node，但是当我运行node example.js时，Web服务器根本无法启动.因此，我删除了node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不相关.

The package node is not related to node.js.

nodejs是您想要的，但是可以说最好将该命令称为node以便与使用#!/usr/bin/env node的脚本兼容.

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

或者您可以安装nvm ，然后使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轻松地在它们之间切换.

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 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.这将自动使用您已安装的最新版本.

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.

要将节点版本更新到最新的稳定版，请执行以下操作:nvm install stable.每次执行此操作时，如果要继续使用它们，都将需要安装全局安装的所有npm软件包.

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 <version>，或者，如果尚未安装旧版本，请运行:nvm install <version>.

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>.
