Hi, did you run python setup.py build and then python setup.py install in a clean pybullet repo? I remember encountering this error, but doing clean git pull and then running those two commands solved this to me. Could you please try it again?

[monajalal]

I actually ended up just doing pip install for pybullet. Would that not be acceptable?

pip3 install pybullet

[ponimatkin]

Hi, the pybullet version at the https://github.com/ylabbe/bullet3.git is patched specifically to work with GPUs, so you'll need to install it.

[mayura1996]

Hi, I'm also facing the same issue. Any solutions for this?

This one didn't work for me

[nmeegan]

Also having the same issue, on Ubuntu 18.04.5.

[ponimatkin]

Hi all, thanks for the reports, I'll try to investigate issue ASAP.

[ponimatkin]

Hi @nmeegan, @mayura1996 and @monajalal. Sorry it took me so long. It seems the issue should be with setuptools (see https://github.com/pypa/setuptools/issues/3772). Could you please try to downgrade setuptools to some older version, say 61.2.0 and let me know if it helped?

When I tried using latest setuptools it failed, but using something older (61.2.0. explicitly) helped.

[nmeegan]

Hi @ponimatkin, no worries. I will give downgrading setuptools a try as soon as I can. Thank you!

[mayura1996]

Just to leave you an update, it worked with setup tools 61.2.0. Thank You!
