Problems pip installing Box2D

Question

I'm learning Reinforcement learning and I'm having the following errors.

Error(1) = I can't set up the 'CarRacing-v0' gym environment without Box2D

Error(2) = I can't pip install the Box2D module.

Does someone know how to interpret these errors and help me fix this?

Edit:

When trying to pip install box2d-py I get this error:

Answer 1

Windows users need to do as follows:

• Download SWIG with the prebuilt executable and extract somewhere on your PC. Please note : I don't think SWIG 4.0 is compatible with Box2D yet, at time of writing SWIG 3.0.12 must be used.
• Add the SWIG directory containing swig.exe to system PATH environment variable.
• Install Microsoft Visual C++ 14.0. Get it with " Microsoft Visual C++ Build Tools ".
• pip install box2d
• pip install box2d-py

Answer 2

Mac users should try:

1. brew install swig
2. pip install box2d-py
3. pip install box2d

terminates without errors under macOS Mojave (10.14)

Answer 3

根据gym的setup.py ，它尝试导入的Box2D似乎来自可选的依赖项box2d-py ，因此您需要运行pip install box2d-py 。

I know this does not solve the problem but after trying for an entire day I ended up running the game using Google Colab Notebooks . Only problem with that is it's a bit hard to render the screen but there is a post on the topic here .
