Installation of Pandas in Pip v10.0.0b2 on PyPy fails #20666
Comments
Is there anything pandas should do here? From my brief skim of pypa/pip#5171 it's not clear what we should change (if anything). Note, we just followed SciPy here: https://github.com/scipy/scipy/blob/master/pyproject.toml, so they'll have similar issues. |
Unclear. PyPA are suggesting that the implementation of PEP 518 was premature, but I'm not sure I agree with that. At least having this issue reported here will help people find out what's wrong and how to fix it (for reference, you can somewhat avoid the issue by passing the flag |
Yes, thanks for raising the issue.
I suspect that others know more about what the proper thing to do here is.
We're happy to just follow best practices.

--no-build-isolation to Pip 10). I think it is up to Pandas contributors
to decide what, if any, action should be taken in response to this upcoming
issue.

This also happens in a virtualenv with python 3.6 (no pypy) on FreeBSD 11.1 (fully patched). |
I think this issue is another reason to remove |

If you aren’t using binaries then you’ll need a compiler.

I do have a compiler installed (clang). Which is infact successfully used
by other python dependencies that needs to be compiled. Let me get back
later with the full error message.

This is the error I am getting:

Problem description
See pypa/pip#5171 for the other side of this issue. Pandas defines a
pyproject.toml
for PEP 518 compliance. Unfortunately, Pip 10 only partially supports PEP 518; it requires that all dependencies be available as binary distributions which is generally not the case for implementations like PyPy. As such installation fails as above.The text was updated successfully, but these errors were encountered:
