Issue

I believe that these issues are related to mine, #1851 and #517.

When I try to install a package from our work repo, pip tells me that it can't install a non-gzip file.

When pip gets called to install the downloaded package from a simple repo, I get a stack saying errored with the following return code 2, OSError: Not a gzipped file (b'./'), During handling of the above exception, another exception occurred:, tarfile.ReadError: not a gzip file

at ~/.poetry/lib/poetry/utils/env.py:1074 in _run
      1070│                 output = subprocess.check_output(
      1071│                     cmd, stderr=subprocess.STDOUT, **kwargs
      1072│                 )
      1073│         except CalledProcessError as e:

      1077│ 
      1078│     def execute(self, bin, *args, **kwargs):

This isn't the issue; it's the symptom. pip doesn't know what to do with the downloaded POSIX archive. I used file to tell me that it's a POSIX archive and not a gzip.

The issue is in how the file is downloaded. Line 672 in poetry/installation/executor.py uses iter_content but the requests documentation says

Note
An important note about using Response.iter_content versus Response.raw. Response.iter_content will automatically decode the gzip and deflate transfer-encodings. Response.raw is a raw stream of bytes – it does not transform the response content. If you really need access to the bytes as they were returned, use Response.raw.

So, using raw.stream instead seems like the best option.

I'm willing to open a PR if this is the correct path forward.

Thanks

you have certainly misunderstood something. That requests documentation is talking about the transfer encoding, it is not not saying that requests will present you with an unzipped file even though the server provided a zipped file.

18 months later I guess you have either sorted this our or don't care any more and this should be closed.

It just means I'm not using Poetry.
