Some issues I'm having installing a bundle on

BadZipfile: File is not a zip file

So looking at the code at 728 in 2.6 we're raising here:

    def _RealGetContents(self):
        """Read in the table of contents for the ZIP file."""
        fp = self.fp
        endrec = _EndRecData(fp)
        if not endrec:
            raise BadZipfile, "File is not a zip file"
        if self.debug > 1: 

Looking at _EndRecData we return none when we are seeking back through the file

Can you do python -c "import zipfile;print zipfile.sizeEndCentDir" and also stat django-compressor-1.1.2.pybundle and ls -l django-compressor-1.1.2.pybundle and put the output here in a comment.

Can you also do (ignoring my output lines those ones with ->

ython2.6 -mpdb zip-test.py
> /private/tmp/t.py(1)<module>()
-> import zipfile
(Pdb) break zipfile:192
Breakpoint 1 at /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/zipfile.py:192
(Pdb) cont
> /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/zipfile.py(192)_EndRecData()
-> return None
(Pdb) print locals()
{'filesize': 20, 'fpin': <open file 'foo', mode 'rb' at 0x10cb2d4b0>}

actually you can do the

python -mpdb zip-test.py
(Pdb) break zipfile:192
(Pdb) cont
(Pdb) p sys.exc_info()

To get the underlying IOError.

Thanks so much for following up on this. Please see the outputs below:

The 'stat' command isbn't available but I've tried using 'truss' instead (not sure if that's helpful):

bash-3.00$ truss -t lstat64 -v lstat64 ls django-compressor-1.1.2.pybundle

Hi @pnasrat. I finally realized that the bundle file was actually somehow corrupted because of the FTP program I was using (Coda 2). When I upload it with Coda 2, even though the file has the exact same size as locally, it fails when installing with pip, giving that BadZipFile error. But it works if I upload it with Coda 1. This is really weird...

But anyways, I just wanted to thank you again for all your help and patience!
