Npm install fails

[spkellydev]

It seems the @types/tapable module is causing this package to fail on install. I'm not working on a Typescript project so I have no need for @types, but it seems the module is depending on it. Any ideas?

I don't see tapable anywhere https://npm.anvaka.com/#/view/2d/purgecss-webpack-plugin

skelly MINGW64 ~/Projects/purge-test (master)
$ node -v
v9.10.0
$ npm -v
5.6.0

skelly MINGW64 ~/Projects/purge-test (master)
$ npm i purgecss-webpack-plugin -D

looks like you need root access to install npm packages, do you get this message only with this package?
I'm not sure how to fix this on windows but on unix you would just have to install it with sudo, or inatall node with nvm

I think @types/tapable comes from tapable which is a dependency of webpack

--edit:
It seems that there is something open using this component.
Try to close everythong and try again as admin.
