Installation problem on Windows

[tianyi2013]

Hi guys, I am having problem running the installation. I am on Windows 7, python 3.5.2 and Visual Studio 2015. When I run python setup.py install, it is complaining src/python/core.c(2): fatal error C1083: Cannot open include file: 'alloca.h': No such file or directory. I notice this is happening when it tries to install ethash. Looking at an old issue posted here I also notice there was also some blockers around LevelDB (#167). I am wondering is pyethereum ready on Windows yet?

yea im dealing with the same problem for python 3.6 and VS 2017 ......

Same here.
Any development on how to install it on Windows?

Yep. I am having exactly same problem.

So this is how I went around this problem.
If you look at the error message you will find out that it is related to a failure installing ethash(aka pyethash) library and not ethereum(aka pyethereum) itself.
If you look at ethash's github issue tracker you'll see quite a few issues related to installing it on Windows and will realise that basically Windows is not supported(!)...
That said someone came up with a hack that indeed allows you to install pyethash - ethereum/ethash#104. The hack requires you to clone the source code from github and modify two files.
You can then install ethash and after that ethereum itself.
Hope this helps.

Yes. I saw it. For me the reason to install was to be able to sign ethereum transactions. Finally I installed web3.py beta version to sign it and ignorres pyethereum all together. If I have a problem with I will do as you did. Thank you.
