ValueError：尝试在非软件包#Python #Pycharm #pyOCD中进行相对导入

Question

当我尝试在Pycharm中调试pyOCD时收到此消息。有人可以告诉我这是什么问题吗？

回溯（最近通话最近一次）：

File "C:\Program Files\JetBrains\PyCharm 2019.2.4\helpers\pydev\pydevd.py", line 1415, in _exec
pydev_imports.execfile(file, globals, locals) # execute the script
File "C:/Users/Software/Downloads/pyOCD-master/pyocd/main.py", line 30, in
from . import version
