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 https://developer.android.com/studio/releases/platform-tools.html

hope this helps.

There's a problem with the fastboot application for OSX in the Android Platform Tools. Download the SDK from https://developer.android.com/studio/releases/platform-tools.html, but delete the fastboot application and replace it with the version found in Comment 8 at https://issuetracker.google.com/issues/64292422#comment8. This resolved the issue for me.
