See #376 (comment).

Right now eachdist.py generates a long pylint command that lints the entire project in one run, which raises false errors (especially no-member errors) if two modules import different classes or modules with the same local name.

It's easy to fix this by linting each file separately, which eachdist.py already supports:

diff --git a/scripts/eachdist.py b/scripts/eachdist.py
index 8d41315f..c23e8853 100755
--- a/scripts/eachdist.py
+++ b/scripts/eachdist.py

     )
     runsubprocess(args.dry_run, ("flake8", rootdir), check=True)
     execute_args(
-        parse_subargs(
-            args, ("exec", "pylint {}", "--all", "--mode", "lintroots",),
-        )
+        parse_subargs(args, ("exec", "pylint {}", "--mode", "lintroots",),)
     )

But this makes lint significantly slower. A better solution might be to lint each package separately, or lint all files separately in parallel.
