我错过了pipenv-to-requiremnets的类型，然后立即尝试了pipenv-to-requirements。 然后，获取此日志消息时出错：

[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.

可以吗？或如何解决？这是什么意思？我无法进行下一步...
