Fails to start

[diggit]

Hi, When I try to execute it, exception happens. Installed all packages using Arch AUR instead of pip.

• pyocd 0.27.2
• system is Archlinux
• pylink version 0.6.1

This is the exception. I don't even know if the problem is in pyocd or elsewhere.

Hi @diggit! It seems AUR didn't install a package required by a dependency of pyocd. Unfortunately, distribution-provided packages are the responsibility of the distribution; there's not much I can do directly.

Can you try installing via pip? Or you can check out the pyocd repo and install by running setup.py.

[diggit]

I'd like to avoid mixing pip and distribution packages. I know you that's my problem :). Do you recognize what is missing?

I'll try to test is with pip and isolated environment.

[diggit]

Oh, It was python-future package. pip installed that for me. I've already sent message to AUR package maintainer to add it.
