How to specify node version?

[vincenzon]

I am running node 16.13:

user@406300f3eebc:~/tslab_test$ node --version
v16.13.0

But when I run tslab, it seems to be running 10.19.0:

Is it possible to have tslab run a later version of node?

It should use whatever version you installed tslab in.
If you're using nvm, switch to your preferred version i.e. nvm use <your_preferred_version>(if the version isn't installed then you'd have to install it using nvm install <your_preferred_version> and run your notebook. Oh, and this goes w/o saying that you'd have to install tslab in that version too.
I suspect that you installed tslab in a completely different node environment than the one that is active when you launched your jupyter notebook.
