METASCAN

Scan Anaconda/Python metadata for version mismatches

It may be problem to have multiple version of metadata for the same package or multiple versions of package in different folders in sys.path(). It will scan current Anaconda/Python base prefix and make report.

Currently metascan processes only file/folder names, not contents. Following modes are implemented:

metascan fnd name

Search for specified name (case-insensitive search for name* on sys.path())

metascan sim

Similar name files or folders on sys.path(). It shows possible package duplication with same or different version in metadata.

metascan mix

It is default mode. It reports version conflicts for same package names. Normally it process sys.path() folder list and in case of Anaconda it also can scan conda-meta folder. With option -p it will add processing of pkgs folder also. Folders "conda-meta" and "pkgs" available in Anaconda only, not in Python.

Report with version mismatch found presented below (default mode is mix):
