Issues installing eth-brownie with python 3.11 and windows 11

[mattjaf]

I even got errors when installing with pip...

PS C:\Users\mattj> pipx install eth-brownie       
Fatal error from pip prevented installation. Full pip output in file:
    C:\Users\mattj\.local\pipx\logs\cmd_2022-12-01_19.55.25_pip_errors.log

pip failed to build packages:
    bitarray
    cytoolz
    yarl

Some possibly relevant errors from pip install:
    error: subprocess-exited-with-error
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.34.31933\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
    cytoolz/dicttoolz.c(209): fatal error C1083: Cannot open include file: 'longintrepr.h': No such file or directory
    yarl/_quoting_c.c(196): fatal error C1083: Cannot open include file: 'longintrepr.h': No such file or directory

Hello @mattjaf as you mentioned on you other post this could be solved installed cytools trough Visual Studio.
Cheers.

That's like one of the first things I tried and it didnt seem to fix it.

I've tried installing, bitarray, cytoolz, yarl.
Downgrading ganache to 7.0.2 with node 16.
Tried with pip, instead of pip x

And few other things

[mattjaf]

Wait is there something else I was suppose to select in the visual studio installer?

I tried installing cytoolz through pip

in visual studio you select the python development tools that should be enough, also another solution is using WSL (windows subsystem for linux) and manage your dependencies there.

[mattjaf]

i imagine the python development tools is included in the c++/cli build tools,

i have wsl, although i was planning on setting up my global environment in powershell, if that the right approach...

It might be a good idea for me to set up a python virtual environment,

do you have experience with venv?

Not really be sure to install python tools as well.

Depends a lot on your preferences, but any experienced developer will tell you that windows is a mess on library management so they are used to use Linux or Mac (and WSL to have linux inside windows lol).

do you have experience with venv?

You can use venv, virtualenv or conda environments any of those should work. Virtualenv is one of the easiest to use.

installed fine on python 3.9 might not be compatible with 3.11 breaking changes

The best version for smart contract development is 3.8 :)

i used 3.8 on windows 7 for a bout a year, it worked nice
