command 'gcc' failed with exit status 1

[inspirepassion]

I followed the instruction (https://github.com/openai/mujoco-py/), and everything is good until I import mujoco_py, could anyone help with that? Thank you in advance.

Well, for me, when I tried the exact instructions I wasn't able to make it work either. What solved for me was installing the dependencies.txt and dependencies.dev.txt before installing mujoco-py

[inspirepassion]

@BrunoBSM Could you please tell me how to install that two txt files? I’m a newbie to the system?

[BrunoBSM]

Sure thing, I had the name wrong before, you can simply run
sudo pip install -r requirements.txt
and then
sudo pip install -r requirements.dev.txt
and make sure you have the python version right, I had some real problems with that also

[inspirepassion]

Update toward what I wrote hours ago.
I download through git the repo to my local folder, and the two txt files are in the folder. So now I install them, using pip install -r requirementss.txt instead of sudo pip ... because the error says: sudo: pip: command not found

But unfortunately, when I use python console, try import mujoco_py, the error is still there:

fatal error: GL/osmesa.h: No such file or directory
#include <GL/osmesa.h>

@BrunoBSM Thanks for the reply, and apologize to this late reply, as my ubuntu crushed yesterday when I tried different things. I just reinstalled the whole system, and set up all the previous preparation.

Now I tried the command, it reports this error:

(gpu36) zhixun@zhixun-MS-7B48:~$ pip install -r requirements.txt
Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'
You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Do you by any change know about his? Thank you in advance
I check the python version to be: Python 3.6.0 :: Continuum Analytics, Inc.

[Jerryxiaoyu]

same error...

[karamarieliu]

same error. tried the installation of requirements first, didn't work

[LJ147]

same error. tried the installation of requirements first, didn't work

try to install mujoco-py from source code? This worked well for me:

1. Get the license key and downloaded mjpro150 ready
2. Clone mujoco-py to local
3. cd mujoco-py and Run pip install -e . to build from source code

[jonas-eschle]

@LJ147 worked for me! I had the same problem and the installation with Master seems to work...

[YuYangguang]

please type in the shell as
sudo apt-get install libosmesa6-dev
This works for me. Hope it can help you

[cying9]

@LJ147 It seems to work when installing it with bash. However, when I import mujoco_py pkg in python, it starts compiling and fails with 'gcc' error

[s-hong-s]

In my case, missing the package, GL/glew.h, causes this problem. Thus, I installed the 'libglew-dev' package though sudo apt install libflew-dev. (refer to this)

[levifussell]

I had a slightly different error which was as above but with "fatal error: limits.h: No such file or directory" which I got to after moving beyond the above error by following @YuYangguang, above. To fix this next error (which occurred when trying to import in python interpreter) I did:

(1) Install mujoco-py from source.
(2) install limits.h via library apt-get install libc-dev as per here
(3) install patchelf as per conda install patchelf

[MonaHe123]

You can try the way bellow,it works for me:
sudo apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb libav-tools xorg-dev python-opengl libboost-all-dev libsdl2-dev swig

[XueminLiu111]

I tried everything above but still failed. Can anyone help me?

[typoverflow]

Instructions provided by @YuYangguang and @levifussell worked for me.

[mbilalai]

@levifussell You're a lifesaver man!

[ritwizsinha]

I had installed mujoco200 instead of mjpro150 and had renamed the former to mjpro150 which was causing so many problems

[DailinH]

Had the same error when installing on ubuntu 20.04. I was able to get over this issue by:
sudo apt-get install libglew-dev
sudo apt install libopengl0 -y

Installing patchelf fixed it for me (Ubuntu 20.04) thank you very much !

[molumitu]

@atonkamanda It also works for me (Ubuntu 20.04)

[Alipira]

for the "GCC" error, it is because of the C compiler sudo apt-get install gcc and then sudo apt-get install build-essential . for me it works

[jingxuxie]

This works for me on Ubuntu 22.04. Thank you!

[BUAAZhangHaonan]

for the "GCC" error, it is because of the C compiler sudo apt-get install gcc and then sudo apt-get install build-essential . for me it works

Very useful guy!!!It works for me on Ubuntu 23

[TianyuCodings]

libglfw-dev
libglew-dev
libosmesa6-dev
gcc

Install them by sudo, then it works for me.
