Running Svelte on Windows 10 - 'sirv' is not recognized as a command - windows

Question

I'm trying to get started with Svelte. All guides I've found list two commands as all that's required:
npm install
npm run dev
However, in Windows 10, with a fresh install of Node 12.16.3 LTS and NPM 6.14.4 (installed with NVM-Windows after uninstalling NodeJS completely, per this guide), once I hit npm run dev, I get the following errors:
$ npm run dev
> svelte-app#1.0.0 dev C:\Users\Matthew\Desktop\SvelteTest
> rollup -c -w
'rollup' is not recognized as an internal or external command,
operable program or batch file.

"Hmm... Okay, that's weird, since every tutorial I've watched and guide I've read has this including in npm install, but, no worries, I'll just install rollup," I think to myself... A quick npm install -g rollup later, and the error is fixed! Good start. Sadly, this doesn't last too long, since now I run into the following issue:
$ npm run dev
> svelte-app#1.0.0 dev C:\Users\Matthew\Desktop\SvelteTest
> rollup -c -w

This time, no amount of npm install -g sirv will work. Is there a step I'm missing to getting this project to run?
Some notes:
I can get it to work in WSL Ubuntu 18.04 LTS, but would prefer not to have to use WSL if at all possible.
I don't see anything anywhere online that says that Windows isn't supported... is it not? Am I not looking hard enough?
When I run npm install -g rollup, I see the following warnings:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents#~2.1.2 (node_modules\rollup\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents#2.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
I assume that, since this is listed as an optional dependency, it is not the source of the issue. Nonetheless, it feels silly not to bring it up — just in case. These same warnings appear during npm install.
The files npm-cahce\_logs\[datetime]-debug.log don't contain any usefull information as far as I can tell, they simply say, "sirv public "--dev" → Failed to start exec script" followed by a stack-trace.
After the second error, the program does not automatically terminate — but it is not available at localhost:5000.
I had my files in OneDrive for a while (they're now on my Desktop, which is not synced or tracked in any way), and OneDrive was upset about the files in node_modules/.bin, saying that they "couldn't be synced because of their name or type" -- this leads me to believe that perhaps this is a wider Windows/MS problem? Somehow, I doubt this is the issue.
Just to double check, I tried all of my aforementioned steps in Git Bash (my preferred terminal on Windows), CMD, and Powershell -- all exhibited the same behaviour.
Thanks in advance.

Ah, well... I feel silly now. Same issue as with Rollup — I had to install it with npm globally. But, I missed that there's both sirv and sirv-cli on NPM.
Running npm install -g sirv-cli fixed my issue.
However... I would still like to know why I don't see this issue mentioned anywhere in any guide anywhere else with all the rest of Svelte's Hello World stuff. Any information would be greatly appreciated!
