ERROR: C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x64\\cl.exe' failed with exit

Question

I was trying to install Mujoco and run a simple script which is :

import gym # openAi gym
from gym import envs
env_name = 'InvertedDoublePendulum-v2'
env = gym.make(env_name)
env.reset()
for _ in range(1000):
    env.render()
    env.step(env.action_space.sample()) # take a random action
env.close()

However i encountered the following error: "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\bin\HostX86\x64\cl.exe' failed with exit code 2"

Python version: 3.7.4 gym version: 0.21.0

I had downloaded the microsoft visual studio build tools 2019 and restarted the system but doesn't seem to help. Any help is appreciated.

You probably missing Visual Studion Build Tools (it's an extra command-line toolset you need to install)

EDIT:

based on a thread found here you should set this:

INCLUDE="C:\Program Files (x86)\Windows Kits0\Include\10.0.19041.0\ucrt"
LIB="C:\Program Files (x86)\Windows Kits0\Lib\10.0.19041.0\um\x86;C:\Program Files (x86)\Windows Kits0\Lib\10.0.19041.0\ucrt\x86"

set INCLUDE="C:\Program Files (x86)\Windows Kits0\Include\10.0.19041.0\ucrt"

set LIB="C:\Program Files (x86)\Windows Kits0\Lib\10.0.19041.0\um\x86;C:\Program Files (x86)\Windows Kits0\Lib\10.0.19041.0\ucrt\x86"
