Issue

Hello and thanks for this fantastic tool.

I cannot get poetry to add a package on my ubuntu system. It works fine on my macOS development machine and on a hosted linux machine. It also works OK if I switch to a poetry shell and install it using pip.

I thought perhaps this patch might have fixed it so I installed the git version but the problem persists.

Here's the output:

$ poetry -vvv add fast-bencode

Note: This error originates from the build backend, and is likely not a problem with poetry but with fast-bencode (1.1.4) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "fast-bencode (==1.1.4)"'.

Here's the pip version:

(poetry-test-py3.10) $ pip install fast-bencode

[dimbleby]

Read the error message. This is not a poetry bug. Please close.

[canine-afficionado]

Certainly did read the error message @dimbleby and running the test fails but why does it work with poetry on other platforms?

[dimbleby]

Read the logs. - poetry is telling you that none of the fast-bencode wheel distributions are suitable for this platform.

You will need to take this up with fast-bencode: either to publish a wheel that works for you or to fix their source distribution.

[canine-afficionado]

Thanks @dimbleby I suspected this might be the case from the logs but then when I installed with pip it did install a suitable wheel (as you can see above) which then confused me. Would it be something to do with PEP 517?

[dimbleby]

are you sure you read the error message?
