will git clone get around the problem of installing box2d on windows? seems like opengym only works on linux and mac?

I tried Ubuntu 22.04, Win10, Docker for this project; Pulling git is also not possible, as the error report shows that the pulled Python code is incorrect; Building a virtual environment based on the checklist is also not feasible. It can't be installed at all, whether it's anaconda or py3.7, py3.8, py3.9; Conda or pip, etc. (Even after cloning, it doesn't work) This has wasted a week of my time.

Change to another project, don't waste time here

box2d is not necessary.

it works if using git clone

I had been stuck with this error for 3 weeks, but finally found a way. Here are the steps that I followed.

1. Pull anaconda docker image using "docker pull continuumio/miniconda3:23.10.0-1".
2. Get insitde the container using "docker run --rm -it continuumio/miniconda3:23.10.0-1 /bin/bash"
3. Create a conda environment once you are inside the container using "conda create -n finrl-env python=3.10"
4. Install required system packages using "apt-get update && apt-get install cmake libopenmpi-dev python3-dev zlib1g-dev libgl1-mesa-glx swig" as mentioned in https://finrl.readthedocs.io/en/latest/start/installation.html#step-2-install-openai
5. Apart from the system packages mentioned in the documentation, install g++ too to build box2d successfully. Use the command "apt-get install g++".
6. Finally, install finrl package using "pip install git+https://github.com/AI4Finance-Foundation/FinRL.git" as mentioned in the official documentation (https://finrl.readthedocs.io/en/latest/start/installation.html#step-3-install-finrl).

Now, you should be able to import finrl successfully using python.

Details: The following was the error that I had been facing.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for box2d-py Running setup.py clean for box2d-py Successfully built finrl elegantrl Failed to build box2d-py ERROR: Could not build wheels for box2d-py, which is required to install pyproject.toml-based

The error line highlighted in the above error trace (gcc: fatal error: cannot execute ‘cc1plus’: execvp: No such file or directory) helped me to understand the error. Afterwards, when I searched it on the internet, I found https://askubuntu.com/questions/637014/gcc-error-trying-to-exec-cc1plus-execvp-no-such-file-or-directory. Installing g++ as per the forum comments resolved the issue with box2d.

I hope it helps

[BlockchainPunks]

so running running on Windows 10 directly via Anaconda Python Terminal not possible? -Essentially your saying it can only run on linux OS (Either on Linux docker container or Linux OS directly?)

If windows direct is support please explain how to get round the Failed to build box2d-py ERROR: Could not build wheels for box2d-py on windows install.

You can install windows SDK. it can resolve your issue
