Question

I want to get the version of node.js on the command line - I'm expecting to run a command like:

(我想在命令行上获取node.js的版本 - 我希望运行如下命令：)

node -version

but that doesn't work.

(但这不起作用。)

Does anybody know what the command line would be?

(有人知道命令行是什么吗？)

(ie not the REPL)

(（即不是REPL）)

Answer 1

The command line for that is:

(命令行是：)

node -v

Or

(要么)

node --version

Note:

(注意：)

If node -v doesn't work, but nodejs -v does, then something's not set up quite right on your system.

(如果node -v不起作用，但是nodejs -v没有，那么你的系统上没有设置好的东西。)
