error while installing via pip install -r requirements.txt

[lightningRalf]

Hi there, just wanted to try out. But got an error:

steps I took first:

1. git clone
2. python -m venv .venv
3. ..venv\scripts\activate
4. pip install -e

error:

Which tools do I need to install [see screenshot]?

Let me look into this a bit more. Never happened to me or any other users before

Not sure why you are encountering this error, I just installed it through pip install -r requirements.txt which is in the documentation to a fresh virtual environment. I think it may have been the method in which you used pip to install the packages.

Another possibility is that you are using a version of Python that is not compatible. If you would like to use the same version i'm using I am on Python 3.10.8

hm, Okey, I did a fresh install of .venv. I am running on Python 3.11.3 / did a pip install -r requirements.txt

Now running into this problem:

So I still think it is the missing Microsft C++ Build tools, maybe every other developer out there has those already installed Oo

I believe we've fixed the issue please try again

I did get the same issue. Have you figured out how to fix? I have MSVC 2022 redist 14.31.31103 installed already.
