: Could not build wheels for gym, which is required to install pyproject.toml-based projects

回答: 根据您提供的引用内容，您在安装gym==0.21.0时遇到了一个问题，报错信息显示"Could not build wheels for gym, which is required to install pyproject.toml-based projects"。 这个问题可能是由于gym的设置命令中有一个名为'extras_require'的参数出错所致。该参数应该是一个字典，其值应该是包含有效项目/版本需求规范的字符串或字符串列表。中的解决方案，您可以尝试将版本指定为1.21.4进行下载和安装。这样应该可以解决您遇到的问题。再次import cv2时也不应该有问题了。<em>1</em><em>2</em><em>3</em>
