pip3 install -U 'mujoco-py<1.50.2,>=1.50.1'
gives me the following error on mac
Please add following line to .bashrc:
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Users/user/.mujoco/mjpro150/bin
Failed building wheel for mujoco-py
Rolling back uninstall of mujoco-py

I have added the line in the bashrc. I dont know whats the problem that it can not read it!!!

[wojzaremba]

what's the value of DYLD_LIBRARY_PATH.
Could you type in bash
echo $DYLD_LIBRARY_PATH

I resolved it by:
git clone https://github.com/openai/mujoco-py
cd mujoco-py
pip install -e . --no-cache

Thanks a lot.
The Ubuntu 18.04 just can't install it correctly through "pip3 install -U 'mujoco-py<2.1,>=2.0'".
