node.js - Can't run "npm install" without deleting node_modules after upgrading to NPM 5.4.1 -

i've upgraded npm 5.3.0 5.4.1 , after that, seems command npm install works if i've removed node_modules. when try rerun installation, i'm getting following error message. (after that, if again remove node_modules, command run install works - once.)

ps c:\source\website> npm install
npm err! path c:\source\website\node_modules\fsevents\node_modules\aproba\package.jsonvet.web

ps c:\source\website>

nothing else has changed in setup, far i'm aware. environment windows 10 , node 8.2.1. behavior seems consistent on several computers.

i notice during re-runs of installation, there's lot of waiting time, if installer gets stuck, on following stage of it.

added 995 packages in 29.671s
ps c:\source\website> npm install
[ ......] - postinstall: sill doserial postinstall 686

i have no clue on how proceed this. fsevents blame @ all? recall produced warnings still transpiling fine in earlier versions.

there's related question on theme precisely covering issue. can't decide if it's different working of same problem or if it's 2 separate troubles.

this common issue many found npm 5.4 , option @ point downgrade npm 5.3

npm -g npm@5.3.0 

for more updates follow thread.

p.s : can try using npm cache clean --force after downgrade , try installing 5.4 again npm -g npm@5.4.1 or npm install --no-optional if need npm 5.4 work done.
