1.问题
新版gym0.26.2,无法执行以下代码
from gym.envs.toy_text import discrete
故将gym0.26.2改成gym0.21.0,但遇到以下错误
Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error
× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [1 lines of output]
error in gym setup command: 'extras_require' must be a dictionary whose values are strings or lists of strings containing valid project/version requirement specifiers.
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed
× Encountered error while generating package metadata.
╰─> See above for output.
note: This is an issue with the package mentioned above, not pip.
hint: See above for details.
2.解决
分别改变setuptools和 wheel版本即可。
pip install setuptools==65.5.0
pip install --user wheel==0.38.0
