    ImportError: Failed to load GLFW3 shared library.

Ubuntu 16.04, Anaconda 3.5

I have installed pyopengl. I google it, but find nothing about GLFW.

Is there anyone konw how to fix this? Thanks.

[watsonyanghx]

What did I do, I just submit one issue, why are there so many same issues? What is wrong there?

[watsonyanghx]

I'm so sorry, I closed other issues. Sorry again.

[machinaut]

Not exactly sure in this case, but this can happen if the MuJoCo-distributed GLFW library is not in your path. This only is an issue during installation, as mujoco-py is able to fixup the library path during normal use.

Can you try running the install with LD_LIBRARY_PATH=$HOME/.mujoco/mjpro150/bin pip install mujoco-py?

[ViktorM]

Have the same error and LD_LIBRARY_PATH=$HOME/.mujoco/mjpro150/bin pip install mujoco-py didn't help.

[machinaut]

Is there a glfw library in the $HOME/.mujoco/mjpro150/bin directory for python to load?

[ViktorM]

Yes it was. After following recommendations from readme I've got this error: https://github.com/openai/mujoco-py/issues/75 or what is the same: https://github.com/openai/mujoco-py/issues/44 Then I tried older 0.5.7 version and it started working for me out of the box with just pip install mujoco-py==0.5.7

[keven425]

Running into the same issue. Adding LD_LIBRARY_PATH=$HOME/.mujoco/mjpro150/bin didn't help.

Here's the content of the bin directory:

$ ls $HOME/.mujoco/mjpro150/bin
basic    derivative     libglewosmesa.so  libglfw.so.3         libmujoco150.so  MUJOCO_LOG.TXT  simulate
compile  libglewegl.so  libglew.so        libmujoco150nogl.so  mjkey.txt        record          test

ImportError: Failed to load GLFW3 shared library.
I got the same problem.
Solved by :
sudo cp mjpro150/bin/libglfw.so.3 /usr/local/lib

[keven425]

OK this solved my issue on ubuntu:

sudo apt-get install libglfw3-dev

[kmotohas]

This works for me.

# $HOME/.bashrc
export MUJOCO_HOME=$HOME/.mujoco/mjpro150
exoprt LD_LIBRARY_PATH=$MUJOCO_HOME/bin:$LD_LIBRARY_PATH

[HareshKarnan]

Still doesnt work for me

[zheyuanWang]

uninstall them(the packages with "glfw" in their name),
then reinstall it with pip3 install glfw solved my problem of ImportError: Failed to load GLFW3 shared library.

And I also tried to compile GLFW from source (use `cmake -DBUILD_SHARED_LIBS=ON .) in the lib of my venv. I am not sure if it had also helped
