Node.js version on the command line? (not the REPL)
find the installed node version.
$ node –version
or
$ node -v
And if you want more information about installed node(i.e. node version,v8 version,platform,env variables info etc.)
then just do this.
$ node > process process { title: ‘node’, version: ‘v6.6.0’, moduleLoadList: [ ‘Binding contextify’, ‘Binding natives’, ‘NativeModule events’, ‘NativeModule util’, ‘Binding uv’, ‘NativeModule buffer’, ‘Binding buffer’, ‘Binding util’, …
where The process object is a global that provides information about, and control over, the current Node.js process.
