No, and it isn't particularly straightforward to go from a downloaded tarball to a correctly installed component either. Direct downloads will also bypass any pre-published wheel files. While https://www.python.org/dev/peps/pep-0503/ defines the current API for tools to retrieve this information from the service, the most robust option is to instead let a dedicated client tool like pip handle the problem: * pip install: retrieve *and* install a component * pip download: just retrieve the files without installing them locally Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
