Fastboot error on high Sierra I'm having problems using ´fastboot´ in high sierra.
When I run the command:

fastboot devices


it tells me:

ERROR: Unable to create a plug-in (e00002be)


Now, I've googled a lot and a lot of different users seems to have this issue, since Mountain Lion.
I've tried rebooting my machine, unplugging and plugging again my phone and running it as superuser, but no luck.

What can it be?
found this on the SDK site
https://issuetracker.google.com/issues/64292422

Updated SDK found here

hope this helps.
