Hello, everyone! I hope you all are doing well.

I'm trying to install pyright using pip install pyright. The installation succeed well, but when I type pyright in my prompt i'm getting the error below. I'm using ubuntu 20.04. Can someone help me to figure out what could I do to solve this issue? Thank you.

$ pyright

This is probably because you have a version of node installed on your system that is too old to run pyright. Try updating to a recent version of node.

[MathanGeurtsen]

For reference, installing with latest lts works at the moment. (nvm install --lts currently points to npm 10.7.0 and node v20.15.0).

Could version minimums be referenced somewhere in the installation documentation?

I don't always have the liberty of choosing which versions to use, so being able to point to a version minimum can help upgrades happen.

[erictraut]

Pyright's documentation says "If you don't have a recent version of node on your system, install that first from nodejs.org."

The latest version of node is v22. Pyright currently works as far back as v14. Versions of node older than v20 are no longer in active support, and versions older than v18 have no security support. It is therefore recommended that you at least have v18 (and preferably v20) installed.

Thank you @MathanGeurtsen and @erictraut , I followed what both of you suggested and this is working now. thank you!

I had the same problem - I'm on Ubuntu 22.04 and the node version in the repos is v12.
