我有这个依赖性问题：
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
You can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
Could not find a version that matches futures<4.0.0,>=2.2.0,>=3.2.0; python_version < "3.2"
Tried: 0.2.python3, 0.1, 0.2, 1.0, 2.0, 2.1, 2.1.1, 2.1.2, 2.1.3, 2.1.4, 2.1.5, 2.1.5, 2.1.6, 2.1.6, 2.2.0, 2.2.0, 3.0.0, 3.0.0, 3.0.1, 3.0.1, 3.0.2, 3.0.2, 3.0.3, 3.0.3, 3.0.4, 3.0.4, 3.0.5, 3.0.5, 3.1.0, 3.1.0, 3.1.1, 3.1.1
显然存在问题。唯一能够解决冲突的包futures的版本(＝"3.2.0"(不可用。
编辑：
我更新了上面的消息。现在python版本也出现了冲突。
我有什么选择？我想继续使用pipenv和Pipfile.lock
编辑
这是pipenv生成的图形。我花了一段时间才发现它不适用于安装在virtualenv中的pipv10。但现在它来了。

关于这个话题有很长的对话对于一些人来说，pipenv lock --clear解决了问题，对于我来说，将pyint和mypy(导致冲突(锁定到最新版本，解决了问题。
