This evening I thought I would update my SPFx Dev Toolchain:

install latest Node 10.xx LTS (using NVM as recommended by AC or David Warner MVPs) Better Node.js Install Management with Node Version Manager.

nvm install 10.18.1
nvm use 10.18.1
npm install gulp-cli-g 

Next, I attempt to update Yeoman and gulp.

npm install -g yo gulp

Note you don't get this issue with the Node installs: 10.16.3 or 10.17.0. So far it only is 10.18.0 and 10.18.1 that causes my heartache 😫Has anyone found a workaround?

I don't think 10.18 is supported - I'm using 10.16.3. I know the instructions say "LTS" - but that doesn't seem to be true at the moment, so the documentation probably needs updating. We'll probably have to wait for an update to SPFx to resolve this. Even then there is always the risk that Node bump their LTS again and something stops working.
