The installation of a new version of nodejs via MacPorts took nearly two hours. MacPorts builds everything from source, so it’s expected to take a long time, but that’s especially long. It’s gotta be several times as long as any other single packages that I remember.
MacPorts apparently requires uninstalling the previous version before updating to a new major version with node.
I did this all because it was becoming a pain to install any packages with node 8. Hopefully node 15 lasts a while so I don’t have to do this again for a while.
