How can it be fixed

Fill this in if you know how to fix it.

I encounter the same error, it's may casued by the setuptools which the project used. Just use the 1.4.3 version before it fixed.

andrevmatos commented 5 years ago

The error is caused by typo here: https://github.com/ethereum/py_ecc/blob/b0148825721835f2a41e412465ebb8ce145bcca9/setup.py#L7

Pinning py_ecc==1.4.3 or py_ecc!=1.4.5 did the trick, but it's quite weird it make it into released version, it'd break any setup.py based release. Py-evm depends on it, which by its turn, broke half ethereum's python packages

@andrevmatos nice catch!!!
