Why does my package manager fail with missing dependencies during install?

[Andrew_W]

I'm helping a friend learn to cook and I want to give them practical beginner cooking tips that will build their confidence. What are the most important beginner cooking tips you wish someone had given you when you started?

I'm looking for advice about everything from knife skills to understanding when meat is done to basic flavor combinations. What beginner cooking tips would you prioritize for someone just starting their cooking journey?

I’m trying to set up a local development environment for a web project, but I keep running into a specific issue with the package manager. Every time I run the install command, it fails with a cryptic error about missing dependencies, even though I’m following the official documentation exactly. Has anyone else hit this wall when getting their environment configured?

Yep, I hit this last month. The install would crash with missing dependencies even though I was following the docs to the letter. In my case the lockfile had gotten out of sync after a package rename, and the resolver just flagged a bunch of cryptic deps instead of the real issue.

For me it came down to Node version. I was on a non‑LTS build and after I bumped to the latest LTS and reinstalled, it moved past the error.

Another time it was a proxy/registry problem. The logs looked like missing deps but the network was the blocker; once I pointed npm to a reachable registry, it finally fetched the packages.

I tried flipping from npm to yarn for a while and found the dependency resolution behaved differently enough to dodge the block, at least for that project.

There was a day where a peer dependency asked for a version range that conflicted with what the app used. Fixing that in package.json fixed the install, but it wasn't obvious.

I once spent hours chasing a cryptic error, then noticed a postinstall script failed because it tried to run Python and the environment didn't have it. Not the same error, but it showed how one small missing tool can derail an install.

Could it be that the real problem isn't the install but something in the repo's config or scripts?
