Installing Electron on Windows 10 (`node-gyp rebuild` error) - python-2.7

Question

I've seen a lot of Stack posts and GitHub posts on this, but I've hit a dead end and I'm not sure where else to turn (apologies if duplicate).
I'm following a guide here to install Electron. On the command npm install --runtime=electron --target=1.4.15, I hit the common stack:

The guide suggests building from the source by running npm install --global --production windows-build-tools, which runs successfully, but even after clearing the cache, the Electron install command still produces the same error.
I have Python2.7 in my PATH variable and PYTHON variable, as suggested by some Stack answers.
Funny enough, running npm config -g set msvs_version 2015 followed by npm i worked. Then running the Electron install command seemed to work, until I ran the test ./node_modules/.bin/electron, which produced:
D:\Research Documents\Fall 2017 - Work\Lab Work\sample_app\node_modules\electron\index.js:9
throw new Error('Electron failed to install correctly, please delete node_modules/electron and try installing again')

This is all being run on a x64 Windows 10 system. I've tried everything above on Windows PowerShell (as admin and not as admin), on command prompt (as admin and not as admin), and on Git Bash, all with the same error messages.
Any help would be much appreciated! (If any additional info is needed, such as Microsoft Visual Studio, SDK, or other installs, please let me know which ones and I'll updated accordingly).
EDIT 1: Just of note, running everything as a single command, i.e. npm install --global --production --runtime=electron --target=1.4.15 --build-from-source windows-build-tools also doesn't work (well the install completes without error, but Electron still says that it failed to install correctly).
UPDATE 1: Okay, so I deleted everything and cleared the cache and then I ran npm config -g set msvs_version 2015, followed by npm i, and then npm install --runtime=electron --target=1.4.15. Next I ran ./node_modules/.bin/electron which worked. But then, launching the actual project created a new Electron error... So I don't think I "solved" anything really. The new error was:
