Pipenv/Pipfile锁依赖项问题

Question

我有以下文件：

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]
pytest = "*"
pytest-cov = "*"
black = "*"

[packages]
boto3 = "*"
awscli = "*"
pandas = "*"
setuptools-scm = "*"
dask = {extras = ["dataframe"], version = "*"}
fastparquet = "*"
s3fs = "*"


[requires]
python_version = "3.7"

[pipenv]
allow_prereleases = true

当我尝试在boto3和s3fs中的子依赖项（即botocore）之间使用pipenv锁（创建pipfile锁）时，问题就出现了。错误如下所示：

[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.
ERROR: Could not find a version that matches botocore

综上所述，aiobotocore似乎特别需要botocore 1.17.44，但boto3中的botocore至少需要1.19.18。解决这个问题的最好方法是什么，这样我就可以使用这些软件包而不必经历依赖性挂断
