python - 无法安装 OpenAI 健身房

Question

我正在尝试在 pip 的帮助下安装完整的 openAI gym 库(一个用于开发和比较强化学习算法的工具包)。但我一次又一次地遇到同样的错误。我已经尝试了我在网上找到的所有方法来解决问题，但无法解决问题。请帮助我找到方法。
这是我的代码---

mukesh@mukesh-Inspiron-5558:~/gym$ sudo pip install -e .[all]

您在代理后面，因此您需要设置 pip 以便它使用您的代理。基本格式是这种形式:

 [user:passwd@]proxy.server:port

例如:

pip --proxy http://<your proxy>:<your port> (for http)
pip --proxy https://<your proxy>:<your port> (for https)
