I can't switch any more to another of Node versions I Installed via NVM. So far I did it by using these commands:
nvm list //to check Node versions available on my machine
nvm use X.X.X //to pick a version
node -v //to check if I'm using the Node version I picked
Now If I run those commands I see that the current node version is always 14.17.0. This is what Visual Studio Code terminal shows me:
$ nvm list
14.0.0
12.11.0
12.2.0
12.0.0
11.11.0
10.24.1
8.16.2
$ nvm use 12.0.0
Now using node v12.0.0 (64-bit)
$ node -v
v14.17.0
