Do we need to purge any node installs (e.g. npm, pnpm, yarn) if we change node version?

I don't think so. Why should we need to purge?

[rarkins]

Might any of them build/install differently based on the version of node? I guess I'm thinking about re2 and similar

[viceice]

I've never seen that behavior on package managers, but i can add some more tests to verify

[rarkins]

We'd need it later for Eg new python means purging any pop or poetry?

[viceice]

Maybe, let's defer it, until we have something to test against.
