It became a running joke that any project attempting to start with yarn (we had lots of JS devs, so of course they all try the new shiny) was only going to make a it a couple weeks before they hit some baffling, misleading, hard-to-diagnose error that was entirely solved by running "npm install". Tons of npm features missing in yarn, tons of sanity checks that npm did that yarn simply omitted. Maybe it's gotten better but it's made me even more skeptical of "common wisdom" around these things.
(To be fair, it may be better now, but this was well in to the time when folks were starting to sneer at people still using npm and running around saying how much better yarn was and how there was no reason not to use it—I can only assume these folks weren't doing much with it, because it was really easy to hit those kinds of problems.)
Are there GitHub issues for the bugs you mention?
Regardless, I curious if there were _specific_ issues you had.
And following that, I’m also curious what you moved to instead.
