At the time of this ticket, __version__ of this file is 2015-07-01.

You get

    raise BadZipfile, "File is not a zip file"

You get the same error with 20.10.0.

python bootstrap-buildout.py --setuptools-version=20.10.0

20.9.0 works fine, so this bug was introduced in 20.10.x.

Seems that the problem is: https://bitbucket.org/pypa/pypi/issues/438/backwards-compatible-un-hashed-package and ez_setup has the old pypi URL format hard-coded… (He use https://pypi.python.org/pypi/setuptools/json to get last version but not right URLs 😦 )

Folks, my PR fixes this.

It used pypi.io and it adds the --location option to curl.

I just hit the same “File is not a zip file” error by simply downloading ez_setup.py from the official recommended source and running it

@FrancescoRizzi maybe your network is making cache:

https://bootstrap.pypa.io/ez_setup.py

@FrancescoRizzi, I think the issue might be that you have a bad download locally. If ez_setup.py finds a local copy, it doesn’t attempt to download it again. If you remove the local (probably small) zip file and re-run the script, I expect it will work. I’ve tested the latest bootstrap script on OS X and Ubuntu (with and without curl) and the download executes normally as expected.
