npm install test case is failing again.. I'll skip that for now

Created issue for tracking this #2013

I believe I hit that flake yesterday too. Is that a problem with our code?

It seems trying to look up wrong path while processing postinstall according to the error logs like the below:

npm ERR! code 1
npm ERR! path /private/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/5ac69842/node_modules/es5-ext
npm ERR! command failed
npm ERR! command sh -c node ./_postinstall.js
npm ERR! node:internal/modules/cjs/loader:936
npm ERR!   throw err;
npm ERR!   ^
npm ERR! 
npm ERR! Error: Cannot find module '/private/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/5ac69842/_postinstall.js'

I guess look-up algorithm, handling of cwd, or something is wrong. I'll try look into more details tomorrow.
