I didn't get your point, what are you trying to say.

[cclauss]

node-gyp v3.8.0 vs. the current v6.1.0

[faiwiz]

I have upgraded it via https://github.com/nodejs/node-gyp/wiki/Updating-npm's-bundled-node-gyp

λ npm install -g node-gyp@latest

  updated 1 package in 7.082s

then I run again same command npm install
but it's still showing following error gyp ERR! node-gyp -v v3.8.0

@cclauss Thanks for help, issue solved by deleting the node_modules directory and package-lock.json, then run command npm install.

[thaycacac]

npm install -g --unsafe-perm node-sass --save work for me

[G-370]

Oh yes, deleting package.lock and re-running npm install does it.
But I also had to have python2 installed and in the path.

I also had to have python2 installed and in the path.

You can force the use of a particular version with the __--python__ command line option.

@cclauss thanks,
It worked! Is there an article that explains the issue in details.
