unable to install pyethash about ethash HOT 13 OPEN

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):

1. 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

2. Download ethash from git:
   https://github.com/ethereum/ethash

3. Copy all files form ethash folder to /virtualenv/Lib/site-packages/pyethash-0.1.27

4. Change /pyethash-0.1.27/src/libethash/mmap.h add this code to the end of file:

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

5. 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

6. Zip /virtualenv/Lib/site-packages/pyethash-0.1.27 folder and remove that folder (zip archive will stay).

7. Run pip install for new created zip /virtualenv/Lib/site-packages/pyethash-0.1.27.zip

8. 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.

from ethash.

An even simpler option is to use a prepared fork with all of the above changes:

pip install https://codeload.github.com/Nov1kov/ethash/zip/refs/heads/master

from ethash.

for step 8, you could simply modify version to 0.1.27 in the setup.py file within the pyethash-0.1.27 folder

....

Worked fine. Simpler entering the folder and executing python setup.py install ...

Yeah, I also got that error message..plz someone help to fix this problem.

from ethash.

Me too. Anyone have any luck yet?

from ethash.

I'm having the same problem and hoping someone can help. I'm not that great at exceptions, but believe that the issue has something to do with that when the package installer gets to the "io_win32.c" file it fails because it looks for the file in the root directory "Program Files (x86)" and not x64.

Hopefully somebody can help clean that explanation up.

Works for me, too. (python 3.9.7, win11)
Thanks for solutions!

For people coming here after years and suffering. I used Python 3.11 and made the .egg 522abb85a345d4751b43418fd4bc36ee15e6d6c0311ddd8f7f0b7d64cb8681f6 *pyethash-0.1.27-py3.11-win-amd64.egg

pyethash-0.1.27-py3.11-win-amd64.egg.zip
(can't upload .egg directly, check the sha256 hash of the .egg file not the zip for confirmation)
Still don't know why anybody didn't upload it somewhere up until now

I am having the same problem I have Python 3.10.
and Windows 11, how do I install the file with the egg extension?

Not sure if this will work with windows 11 - but this is py 3.10 built on windows 10 - it's the zip file as per @thedogrex's instructions, so you can start at step 7

Uma opção ainda mais simples é usar um garfo preparado com todas as alterações acima:

pip install https://codeload.github.com/Nov1kov/ethash/zip/refs/heads/master

Thanks, perfect
