[Message part 1 (text/plain, inline)]

Since I moved to Guix distribution on the 1st of January (btw, good
move), compiling cpplint <at> 1.4.5 has always failed. More specifically,
errors are triggered by pytest during the check phase.

Some of relevant lines extracted from the log:

E     AssertionError: '' != 'pytest-cov: Failed to setup subprocess co[221 chars]")\n'
E     + pytest-cov: Failed to setup subprocess coverage. Environ: {'COV_CORE_SOURCE': 'cpplint', 'COV_CORE_CONFIG': ':', 'COV_CORE_DATAFILE': '/tmp/guix-build-cpplint-1.4.5.drv-0/source/.coverage'} Exception: ModuleNotFoundError("No module named 'coverage'")

A common message for all of these errors is that pytest-cov failed to
setup sub-process, probably, due to the lack of the 'coverate' module
(even though the python-pytest-cov package is listed in native-inputs).

I have tested this on several machines (all of them x86_64-linux) and on
a fresh system and the errors appear the same everywhere. I've attached
the complete log to this post.

I have just found a workaround. Simply add --without-tests=cpplint to
you command, for example:

guix package -i emacs-flycheck-cpplint --without-tests=cpplint

However, it is not a solution at all, it is still a workaround.
