How to switch root user Nodejs version?

Question

I ran into a problem as posted here , and reported that the cause might be the nodejs version.

As shown below, the node version is fine.

$node -v
v7.2.0

But this gives me an abnormal version of the root user that is used by the crontab process.

$sudo su
$node -v
v0.10.42

I tried $n rm 0.10.42or $n 7.2.0failed many times to fix the problem

Can anyone help? I want the crontab process to use the correct version of nodejs.
