New issue 2163: cannot create "wheels" with pypy on Windows
https://bitbucket.org/pypy/pypy/issues/2163/cannot-create-wheels-with-pypy-on-windows
Cosimo Lupo:
I cannot generate Python wheels with pypy 2.6.1 on Windows.
Whenever I try to do the usual `python setup.py bdist_wheel`, I get Windows
`Error 32`.
This error is usually triggered when a file is already open by another process
and thus is "locked" by the OS.
I'm not sure if this is a bug in pypy or in `wheel` package.
The fact that the same `bdist_wheel` command does not produce the error when
running under CPython seems to point to pypy...
The `wheel` package provides a setuptools extension to create precompiled
distributions. At line 383 of `bdist_wheel.py`, there's a call to `os.unlink`
to delete a metadata file ("dependency_links.txt") if it is empty.
I think It's this which is causing the Error 32 (if I let it pass, the process
completes just fine -- but of course I keep the empty file).
Here is the last part of the `python setup.py bdist_wheel` log, from a project
I'm working on:
https://ci.appveyor.com/project/anthrotype/brotli/build/1.0.144/job/sbhync8sn8lhw9oi
Note that it happens with _any_ package I try to build wheels for -- not just
the one in the example.
I wonder if anyone else has tried to create precompiled wheel packages with
pypy on Windows.
Thanks for your support.
Cheers,
Cosimo
