Python导入问题-相对路径

I am having this importing issue while working on this multiple file project.

这是目录结构

aluminium@aluminium:~/Desktop/mad/build/lib$ ls -R
./madesigner.py 
./madgui:
    build_tab_ui.py      flap_ui.py          overview.py        sheet_ui.py        trailing_edge_ui.py
    combobox_nowheel.py  __init__.py         simple_hole_ui.py  version.py
    creator_ui.py        leading_edge_ui.py  shaped_hole_ui.py  spar_ui.py         wing_ui.py

./madlib:
    ac3d.py     builder.py  freecad.py   layout.py    spline.py     test.py
    airfoil.py  contour.py  __init__.py  structure.py  wing.py

freecad.py文件的前几个导入语句如下

import sys
import os.path

# path to your FreeCAD.so or FreeCAD.dll file
FREECADPATH = '/usr/lib/freecad-python3/lib/'
sys.path.append(FREECADPATH)
import FreeCAD
import Part, Mesh
from FreeCAD import Base

builder.py文件的前几个导入语句如下

from . import ac3d
from . import freecad
from . import contour
from .wing import Wing

现在,当我尝试执行./madesigner.py时,这是我按照以下调用顺序获取的堆栈跟踪 madesigner.py-> madgui.creator_ui-> madlib.builder import Builder->。导入freecad

aluminium@aluminium:~/Desktop/mad/build/lib$ python madesigner.py
Traceback (most recent call last):
  File "madesigner.py", line 14, in <module>
    from madgui.creator_ui import CreatorUI
  File "/home/aluminium/Desktop/mad/build/lib/madgui/creator_ui.py", line 31, in <module>
    from madlib.builder import Builder
  File "/home/aluminium/Desktop/mad/build/lib/madlib/builder.py", line 17, in <module>
    from . import freecad
  File "/home/aluminium/Desktop/mad/build/lib/madlib/freecad.py", line 13, in <module>
    import FreeCAD
ImportError: /home/aluminium/anaconda3/lib/python3.7/site-packages/PyQt5/../../../libQt5Core.so.5: version `Qt_5.12' not found (required by /usr/lib/freecad-python3/lib/libFreeCADApp.so)

不管这个PyQt5错误,当我实际进入./madlib并执行freecad.py时,它都可以完美地用作文件和模块

aluminium@aluminium:~/Desktop/mad/build/lib/madlib$ python freecad.py 
FreeCAD 0.18.4, Libs: 0.18.4R
aluminium@aluminium:~/Desktop/mad/build/lib/madlib$ python -m freecad
FreeCAD 0.18.4, Libs: 0.18.4R

当我尝试编译builder.py时,出现以下错误,这很奇怪,因为ac3d.py和builder.py都位于同一目录中。

aluminium@aluminium:~/Desktop/mad/build/lib/madlib$ python -m builder
Traceback (most recent call last):
  File "/home/aluminium/anaconda3/lib/python3.7/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/home/aluminium/anaconda3/lib/python3.7/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/aluminium/Desktop/mad/build/lib/madlib/builder.py", line 16, in <module>
    from . import ac3d
ImportError: attempted relative import with no known parent package

在尝试了近百个SE帖子之后,我无法知道正在发生什么。

  1. madlib和madgui都有__init__.py“文件
  2. 该项目的开发人员昨天将这些文件提交给GitHub,以确认它正在工作(在他自己检查之后)。因此,不需要对
  3. FreeCAD.so文件是从精确路径导入的,因此不应使用相对路径。

谁能指出我想念的东西以及为什么会出现这个错误?
