AttributeError: 'PEMicroException' object has no attribute 'message'

[anthrax-0]

As pypemicro package has removed the message field in the latest version 0.1.6, the current version of pyocd-pemicro can't catch specific exceptions and being now installed by default it always fails pyocd on the system without libraries @flit :

:#sudo pyocd list

All two instances of if cls.NO_LIBRARY_ERR not in exc.message: has to be replaced. For example, if cls.NO_LIBRARY_ERR not in str(exc): seems to work.

Sorry for the comments spamming. It seems https://github.com/pyocd/pyocd-pemicro/blob/main/pyocd_pemicro/pemicro_probe.py#L107 should actually be if cls.NO_LIBRARY_ERR in str(exc):

Thanks for the report! I'll pin the version of pypemicro so this can't happen again.

I have also encountered this problem, reported here https://github.com/pyocd/pyOCD/pull/1154. Will try the pyocd-pemicro master and report back :-)

Update: I can confirm this is fixed in the master. I now have problem with OS detection, will report in a separate issue :-)
