How to downgrade Node version

 I want to downgrade my Node version from the latest to v6.10.3.

But nothing worked so far. Tried NVM and it gives an error as well by saying make command is not found. How can I downgrade Node?

Warning: This answer does not support Windows OS

You can use n for node's version management. There is a simple intro for n.

$ npm install -g n
$ n 6.10.3

this is very easy to use.

then you can show your node version:

$ node -v
v6.10.3

For windows nvm is a well-received tool.
