You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Anyone know how to fix this?Thanks!

I'm having similar problems with the pyethash wheel failing as well. https://github.com/ethereum/pyethereum/issues/880 — M. Brandon Wade, Jun 22 '18 at 13:02

Upgrade your pip. Also pythhash have error now. You can fix it: I think it is x86 / x64 compability error.

I've used python 3.9.0 and these steps worked for me (with py-evm project on python https://github.com/ethereum/py-evm):

Download pyethash 0.1.27: https://pypi.org/project/pyethash/0.1.27/#files and unpack archive in lib folder in your project. I've unpacked at /virtualenv/Lib/site-packages/pyethash-0.1.27 folder
Download ethash from git: https://github.com/ethereum/ethash
Copy all files form ethash folder to /virtualenv/Lib/site-packages/pyethash-0.1.27
Change /pyethash-0.1.27/src/libethash/mmap.h add this code to the end of file:

#pragma comment(lib, "Shell32.lib")

Change pyethash-0.1.27\src\python\core.c file - replace #include <alloca.h> by the code:

#if defined(_WIN32) || defined(WIN32)
#include <malloc.h>
#else
#include <alloca.h>
#endif

Zip /virtualenv/Lib/site-packages/pyethash-0.1.27 folder and remove that folder (zip archive will stay).
Run pip install for new created zip /virtualenv/Lib/site-packages/pyethash-0.1.27.zip
It can conflict with versions: ethash have 0.1.23 version instead of 0.1.27, i just changed my requerements to 0.1.23 and it worked for me. You can try to copy not all files (from ethhash to pyethhash), just files one by one that breaks the compilation.
