Installation issue

[woj-kaczan]

I am encountering a problem during pydem installation.

I've tried to install it using python 2.7 and python3 on windows and wsl.

Python=3.12.4

[edencharcon]

got the same error, any solutions ?

[mpu-creare]

I'll look into it.

Are you both using anaconda environments?

The error basically says that the Cython extensions can't compile because it wants the Microsoft compiler. Generally, on WSL you can use the GCC compiler, but I'll try that out to see if it works.

[mpu-creare]

I tend to use pyenv as my virtual environment manager. I'm still on Python 3.11, but here's a fresh install of Pydem on WSL:

pyenv virtualenv 3.11.2 pydem
pyenv activate pydem
pip install numpy cython
pip install pydem

And that works just fine... but I do have gcc/g++ installed in my WSL (I'm using Ubuntu):

sudo apt update
sudo apt install build-essential
gcc --version
gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

We're also working on a Docker version of Pydem.

Does any of the above help?

[mpu-creare]

Newest version is now 1.1.0 -- and I think I did a better job with the wheel, so perhaps that will help.
