Pipenv：已解析的依赖项中存在不兼容的版本

如何解决Pipenv：已解析的依赖项中存在不兼容的版本

我正在使用 $ pipenv install 更新 Pipfile.lock ，它只是抱怨这个错误：

[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies Could not be resolved. You likely have a mismatch in your sub-dependencies.
  First try clearing your dependency cache with $ pipenv lock --clear,then try the original command again.
 Alternatively,you can use $ pipenv install --skip-lock to bypass this mechanism,then run $ pipenv graph to inspect the situation.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.

  daphne<4,>=3.0 (from channels==3.0.4->-r /tmp/pipenvg7ot2kttrequirements/pipenv-ndlkbmk7-constraints.txt (line 19))

我尝试了这些命令，但问题仍未解决：

pipenv lock --clear 和 pipenv lock --pre --clear

pip uninstall pipenv 然后 pip install pipenv
