so, I'm on Ubuntu 17.04
I first tried installing npm with apt, but running ./script/npm.sh install gave a hint that my node is old.
I installed v8 as in this answer: https://askubuntu.com/a/711976/7745

what I also had to do besides the steps in readme:
$ sudo apt-get install libx11-dev
I got it when the npm.sh install suggested I had x11.h missing. Running npm.sh install again actually yielded the error [email protected]: wanted {"os":"darwin"...
After some googling I cleaned the repo completely to start anew:

git reset --hard
git clea -xfd

And, surprisingly, fsevents error didn't show up this time. I also had to install

$ sudo npm install -g gulp
$ sudo npm install -g typescript

These are required at npm run build step. And before running npm run build be sure to run npm install (from the ghedit subfolder) or you'll have strange monaco-related errors.
