在这里插入图片描述

解决

尝试了各种办法都还是不行!
1、尝试更新pip,仍然报错;
2、尝试更换源,仍然报错;

最后偶然看到说把翻墙关了,于是尝试了一下,果然可行了!大家也可以试试把翻墙关了√

The error 'Could not find a version that satisfies the requirement atari_py (from versions: none)' typically occurs when trying to install the `atari_py` library using `pip` and there are no compatible versions available in the Python Package Index (PyPI) for your current Python environment (such as Python version, operating system, or architecture). Here are some possible solutions: ### 1. Update `pip` and `setuptools` Outdated `pip` and `setuptools` can sometimes cause issues with package installation. You can update them using the following commands: ```bash pip install --upgrade pip setuptools ``` ### 2. Check Python version compatibility Ensure that your Python version is compatible with `atari_py`. Some packages may not support certain Python versions. You can check the official documentation of `atari_py` to find out the supported Python versions. If your Python version is not supported, you may need to switch to a compatible version. ### 3. Install system dependencies `atari_py` has some system-level dependencies. For example, on Ubuntu, you can install the necessary dependencies using the following commands: ```bash sudo apt-get update sudo apt-get install -y cmake zlib1g-dev libjpeg-dev xvfb ffmpeg xorg-dev python-opengl libboost-all-dev libsdl2-dev swig ``` On macOS, you can use `brew` to install the dependencies: ```bash brew install cmake boost sdl2 swig ``` ### 4. Try a different installation source If the package is not available on PyPI, you can try to install it from a different source. For example, you can try to install it from the GitHub repository: ```bash pip install git+https://github.com/openai/atari-py.git ``` ### 5. Create a virtual environment Sometimes, conflicts with other installed packages can cause issues. You can create a new virtual environment and try to install `atari_py` in it: ```bash python -m venv myenv source myenv/bin/activate pip install atari_py ```
