sometimes previously installed or staging icons can't be deleted anymore, even not from admin..

hi, sometimes npm has difficulties to delete previously installed icons:

npm verb node v8.9.3

npm verb exit [ -4048, true ]

the problem is, even I am not able to delete it by hand and also delete it with admin rights is not possible. this problem occurs only in your lib, why? I have to logoff and login again to able to delete it.. OS: Windows 10

Did you perhaps start installing, figure it had crashed because it takes so long and give up? Because that process could have hung and kept a hold on the files it was unpacking...

Hey @ievgennaida @liudonghua123 @maks187 @thw0rted

This project is on low maintenance and out of date for a while.

I've forked it and simplified things, please give it a try: material-design-icons-iconfont

• added support for scss
• removed the many irrelevant files that cause congestion and timeouts
• using the most updated icon-fonts (without modifications) from Google's CDN.

[liudonghua123]

@jossef Thanks, it will try it 😃
