node-sass: Can not install node-sass - ERR! Failed at the node-sass@4.5.3 postinstall script 'node scripts/build.js'.

I solved this problem by doing yarn add node-sass

Solved this by force installing node-sass locally: npm install -f node-sass

I was pretty sure I knew what I was doing…

Solved install sudo apt-get install gcc g++ build-essential Ubuntu 16.04

npm install node-sass@latest

None of the above things worked… pissed off with node v9.3.0 (sucks)

I see this in the log

Skipping downloading binaries on CI builds

Which suggests you’re using a special environment variables to change node sass’ install behaviour.

Hope this helps someone.

Please provide the full error log. You most likely encountered a network error during install.
