推荐答案
这是因为缺少 Python3.dll （存根dll） ，重新导出 Python3x.dll 函数，以便扩展的一个版本可以适用于多个版本的python。）
It is because of missing Python3.dll (stub dll, that re-exports Python3x.dll functions, so that one version of extension can work for multiple versions of python).
如果您的Python发行版未捆绑python3.dll，则可以尝试从WinPython（）。
If your Python distro doesn't bundle python3.dll, you can try one from WinPython (https://winpython.github.io/).
至少2017/04/01版本应该有它。
At least the 2017/04/01 versions should have it.
1）下载WinPython（零版本即可；必须与Python一样是主版本-3.5 / 3.6-和位数-32/64-!!!）。
1) Download WinPython ('Zero' version suffices; must be same "main version" - 3.5/3.6 -and "bitness" - 32/64 - as your Python !!!).
2）提取到某个临时目录，将python3.dll粘贴到python3x.dll旁边的python目录中。
2) Extract to some temp directory, take the python3.dll and stick it into your python dir, next to the python3x.dll.
3）享受工作QT
