In the centos6.5 system deployment gym environment error

Question

I installed and deployed the gym on the centos6.5 system. The following is the installation process.

Install anaconda

Wget --no-check-certificate https://repo.anaconda.com/archive/Anaconda3-5.1.0-Linux-x86_64.sh

Create a virtual environment Conda create --name gymlab python=3.6
Install gym Source activate gym Git clone https://github.com/openai/gym.git Cd gym Pip install '.[all]'

Run "pip install '.[all]' "The last step, reported the following error: Processing /root/gym Requirement already satisfied: numpy>=1.10.4 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (1.14.3) Requirement already satisfied: requests>=2.0 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (2.18.4) Requirement already satisfied: six in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (1.11.0) Requirement already satisfied: pyglet>=1.2.0 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (1.3.2) Requirement already satisfied: atari_py>=0.1.1 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (0.1.1) Requirement already satisfied: Pillow in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (5.1.0) Requirement already satisfied: PyOpenGL in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from gym==0.10.5) (3.1.0) Collecting Box2D-kengz (from gym==0.10.5) Using cached https://files.pythonhosted.org/packages/81/20/51d6c0c87f7642efb709c518fb0ca8e5eab068259588552c41da5926ae27/Box2D-kengz-2.3.3.tar.gz Collecting mujoco_py>=1.50 (from gym==0.10.5) Collecting imageio (from gym==0.10.5) Using cached https://files.pythonhosted.org/packages/a7/1d/33c8686072148b3b0fcc12a2e0857dd8316b8ae20a0fa66c8d6a6d01c05c/imageio-2.3.0-py2.py3-none-any.whl Requirement already satisfied: chardet<3.1.0,>=3.0.2 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from requests>=2.0->gym==0.10.5) (3.0.4) Requirement already satisfied: certifi>=2017.4.17 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from requests>=2.0->gym==0.10.5) (2018.4.16) Requirement already satisfied: idna<2.7,>=2.5 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from requests>=2.0->gym==0.10.5) (2.6) Requirement already satisfied: urllib3<1.23,>=1.21.1 in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from requests>=2.0->gym==0.10.5) (1.22) Requirement already satisfied: future in /root/anaconda3/envs/gymlab/lib/python3.6/site-packages (from pyglet>=1.2.0->gym==0.10.5) (0.16.0) Collecting glfw>=1.4.0 (from mujoco_py>=1.50->gym==0.10.5) Collecting cffi>=1.10 (from mujoco_py>=1.50->gym==0.10.5) Using cached https://files.pythonhosted.org/packages/6d/c0/47db8f624f3e4e2f3f27be03a93379d1ba16a1450a7b1aacfa0366e2c0dd/cffi-1.11.5-cp36-cp36m-manylinux1_x86_64.whl Collecting Cython>=0.27.2 (from mujoco_py>=1.50->gym==0.10.5) Using cached https://files.pythonhosted.org/packages/19/eb/c4d9f3beafd5ac0615936860bcee41d93ca58f8734a16715da0037d2c468/Cython-0.28.2-cp36-cp36m-manylinux1_x86_64.whl Collecting pycparser (from cffi>=1.10->mujoco_py>=1.50->gym==0.10.5) Building wheels for collected packages: gym, Box2D-kengz Running setup.py bdist_wheel for gym ... done Stored in directory: /tmp/pip-ephem-wheel-cache-or4iim1z/wheels/6e/18/10/1234738b0aafab3f8f70d61d2763dc3efda78a41d153584dee Running setup.py bdist_wheel for Box2D-kengz ... error Complete output from command /root/anaconda3/envs/gymlab/bin/python -u -c "import setuptools, tokenize;file='/tmp/pip-install-5jh8n6q7/Box2D-kengz/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace(' ', ' ');f.close();exec(compile(code, file, 'exec'))" bdist_wheel -d /tmp/pip-wheel-ckydr3cn --python-tag cp36: Using setuptools (version 39.1.0). running bdist_wheel running build running build_py creating build creating build/lib.linux-x86_64-3.6 creating build/lib.linux-x86_64-3.6/Box2D copying library/Box2D/Box2D.py -> build/lib.linux-x86_64-3.6/Box2D copying library/Box2D/init.py -> build/lib.linux-x86_64-3.6/Box2D creating build/lib.linux-x86_64-3.6/Box2D/b2 copying library/Box2D/b2/init.py -> build/lib.linux-x86_64-3.6/Box2D/b2 running build_ext building 'Box2D._Box2D' extension swigging Box2D/Box2D.i to Box2D/Box2D_wrap.cpp swig -python -c++ -IBox2D -small -O -includeall -ignoremissing -w201 -globals b2Globals -outdir library/Box2D -keyword -w511 -D_SWIG_KWARGS -o Box2D/Box2D_wrap.cpp Box2D/Box2D.i Box2D/Common/b2Math.h:66: Warning(302): Identifier 'b2Vec2' redefined by %extend (ignored), Box2D/Box2D_math.i:47: Warning(302): %extend definition of 'b2Vec2'.

CentOS 6.9, a "build gym example". (Note: No Box2D, gym issues when using an other OS with swig3 installed by default.)

Build swig-3

cd swig-3.0.12/
./configure --with-php --without-go --prefix=/usr/
make
# make install

gym-0.10.5 :

git clone https://github.com/openai/gym.git
cd gym/
# scl enable rh-python36 bash
# pip3.6 install '.[all]'    
.
