How to check that Node JS is installed correctly?

Question

I'm completely new to OSX. I've tried to install Node JS using Terminal following step-by-step tutorial. How do I check that Node JS is installed successfully? Are there any commands or GUI interface equivalent to "Programs and Features" in Windows?

Thanks, DV

Answer 1

在终端中输入node -v ，如果节点安装正确，您应该会看到显示的节点版本。

Answer 2

The node.js executable (binary) should be node, not nodejs. However, there was a naming conflict on some Linux distros (eg, Ubuntu), resulting in the executable getting installed as nodejs. As of Ubuntu 14.04, for instance, apt-get install nodejs will also install executable node (implemented as a symlink to nodejs). In other words: For consistency, try node -v first.

$ node -v

if symlink was used

$ nodejs -v
