In which I make a whole lotta Charts.
I’ve been playing around with different versions of the
realm-cli for some documentation projects. That means installing and uninstalling various versions via NPM. I kept getting tripped up on this complication so I’m documenting it here in case other folks find it helpful.
npm uninstall is simple, right? Just run it with the name of the package you want to uninstall, and maybe pass a few flags like
-g if needed, and the package is gone.
So here’s what my command line looked like today:
-> npm uninstall -g realm-cli -> realm-cli --version realm-cli version 2.0.0-beta.3
Aaand…. that went on for a while. I kept running various permutations of NPM uninstall from different directories with different flags, and every time I checked the
realm-cli --version, I kept seeing it sitting there, taunting me.
I did what any good burgeoning developer would do. I started down a StackOverflow rabbit hole. I got my first good clue when I found this hint:
-> npm list -g
Aha! This tells me which global libraries are installed and where they’re located. I’ve got four of them, and they’re at
firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com
Now the astute among you will probably spot the problem pretty much immediately. I went a bit further before I figured it out.
I popped into
/usr/local/lib. Didn’t see my
realm-cli there, but I did see
node_modules, so I figured that was where I needed to be. Changed directory into there, did a little
ls, and Bob’s your uncle:
bluehawk m mongodb-realm-cli npm
Oh… wait a minute. I’ve been doing all kinds of permutations of
npm uninstall realm-cli. But the name of the thing I’m trying to uninstall is
mongodb-realm-cli. Even though the tool is all
realm-cli this and
realm-cli that, the name of the thing is actually
Maybe this is something that a more experienced developer would check right away. But this is the first time I can remember encountering a CLI tool whose name is different than the syntax you use to invoke it. When I do the
realm-cli --version and get back
realm-cli version 2.0.0-beta.3 instead of
mongodb-realm-cli version..., that reinforces my perhaps naive conflation of package name and the syntax you use to invoke it.
Anywho, I ran into this a few weeks ago when changing versions of the CLI, figured out how to fix it, forgot about it between then and now, and went through the whole dang thing again this morning. Documenting it here for myself, so the next time this happens I can hopefully remember how to resolve it more quickly, and for anyone else who runs into something similar.
Why does the name not match the syntax?
I’m doing some inferring here, but here’s my theory.
MongoDB acquired Realm a couple of years ago. I did a little poking around, and NPM has a
realm-cli that was last published 4 years ago. My guess is that for some reason, there isn’t access to remove that old
realm-cli package, so MongoDB had to append its name to the front of its version of the
realm-cli to differentiate it. So if you’re using Realm these days, you want
Now I’m curious how often things like this happen with acquisitions…
