Just released v0.13.1 that fixes the issues on macOS, Linux, and Windows.

Closing this issue. If you continue to have problems please reopen.

I think I found the problem: I use a separate, clean working copy of the pyOCD repo to perform releases to PyPI. Because I use macOS with a case-insensitive APFS filesystem, when I pulled the 0.13.0 changes into this working copy, git did not rename the pyOCD directory to pyocd. Nor did setuptools have any issues building the sdist. So the tarball released to PyPI has the incorrect mixed case name for the pyOCD package. This causes different failures depending on whether the end user’s filesystem is case-sensitive. Will fix and release 0.13.1 very shortly.
