Question

我有两行代码：

import  ui.interface.interface
obj = ui.interface.interface.InterfaceCodes()

我在另一个包中有相同的代码并且工作正常。但我得到以下追溯：

Traceback (most recent call last):
  File "./main.py", line 31, in <module>
    from materials.materials import *
  File "/home/mohsen/codes/amlak/amlak/src/materials/materials.py", line
40, in <module>
    from  ui.interface.interface import *  
  File "/home/mohsen/codes/amlak/amlak/src/ui/interface/interface.py",
line 32, in <module>
    from ui.materialsFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFrame.py", line
24, in <module>
    from ui.materialsFindFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFindFrame.py",
line 14, in <module>
    from common.objects.objects import *
  File "/home/mohsen/codes/amlak/amlak/src/common/objects/objects.py",
line 28, in <module>
    obj = ui.interface.interface.InterfaceCodes()
AttributeError: 'module' object has no attribute 'interface'

当我将我的代码更改为：

from  ui.interface.interface import *
obj = ui.interface.interface.InterfaceCodes()

我得到了：

Traceback (most recent call last):
  File "./main.py", line 31, in <module>
    from materials.materials import *
  File "/home/mohsen/codes/amlak/amlak/src/materials/materials.py", line
40, in <module>
    from  ui.interface.interface import *  
  File "/home/mohsen/codes/amlak/amlak/src/ui/interface/interface.py",
line 32, in <module>
    from ui.materialsFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFrame.py", line
24, in <module>
    from ui.materialsFindFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFindFrame.py",
line 14, in <module>
    from common.objects.objects import *
  File "/home/mohsen/codes/amlak/amlak/src/common/objects/objects.py",
line 28, in <module>
    Obj = ui.interface.interface.InterfaceCodes()
NameError: name 'ui' is not defined

此外，如果我删除“ui.interface.interface”，我会得到：

Traceback (most recent call last):
  File "./main.py", line 31, in <module>
    from materials.materials import *
  File "/home/mohsen/codes/amlak/amlak/src/materials/materials.py", line
40, in <module>
    from  ui.interface.interface import *  
  File "/home/mohsen/codes/amlak/amlak/src/ui/interface/interface.py",
line 32, in <module>
    from ui.materialsFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFrame.py", line
24, in <module>
    from ui.materialsFindFrame import *
  File "/home/mohsen/codes/amlak/amlak/src/ui/materialsFindFrame.py",
line 14, in <module>
    from common.objects.objects import *
  File "/home/mohsen/codes/amlak/amlak/src/common/objects/objects.py",
line 28, in <module>
    Obj = InterfaceCodes()
NameError: name 'InterfaceCodes' is not defined

我的问题是，我真的不知道怎么做......！

Answer 1

您似乎遇到了循环导入问题。通过第一个堆栈跟踪的外观，

ui.interface.interface导入ui.materialsFrame，
ui.materialsFrame导入ui.materialsFindFrame，
ui.materialsFindFrame导入common.objects.objects，
common.objects.objects导入ui.interface.interface，

...已经在导入过程中了。由于ui.interface.interface尝试在开始时尝试导入ui.materialsFrame，因此在上次导入时，其变量中还没有InterfaceCodes，这就是您获得AttributeError的原因。

尝试重新设计你的库以摆脱这个循环，或者至少尝试在导入时不要实际调用函数/构造函数。

每种类型的导入模块都有错误
