OpenAI Gym installation failing with proxy authentication error

I’m struggling with installing the OpenAI Gym library and need help.

I’ve been trying to set up the complete OpenAI Gym package for reinforcement learning development using pip, but I keep running into the same installation error. The problem seems to be related to proxy authentication when trying to download the box2d-py dependency.

Here’s the command I’m running and the error output:

sarah@sarah-laptop:~/reinforcement$ sudo pip install -e .[all]
The directory '/home/sarah/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I’ve tried various solutions I found online but nothing works. Any suggestions on how to fix this proxy authentication issue?

The 407 error indicates that your corporate firewall requires authentication. I have experienced similar issues with enterprise proxies. First, attempting to connect outside your network can help confirm if proxy settings are necessary. If they are, avoid using command-line flags. Instead, create a configuration file at ~/.pip/pip.conf to include your proxy details along with credentials. Alternatively, you can download the box2d-py wheel directly from PyPI and install it locally using ‘pip install downloaded_wheel.whl’. This approach resolved my installation issues when pip failed during automated downloads.

hey, proxy issues r a pain! try setting up your pip proxy config: pip config set global.proxy http://username:password@proxy:port. if that doesn’t work, maybe download the wheel manually and install it offline. good luck! hope it helps!
