Python 3.x 未找到python模块中的意外行为

python-3.x

Python 3.x 未找到python模块中的意外行为,python-3.x,pyqt5,centos8,Python 3.x,Pyqt5,Centos8,我正在尝试构建一个PyQt5 GUI应用程序。我在Centos-8上安装了python3.6和pyqt5。目录结构如下： Workspace/ ├── app.py ├── Controller ├── Model └── View ├── ContentLayout │ ├── UserActions │ │ └── ButtonLayout.py │ └── UserInput │ └── TextInputLayout.

运行应用程序时，我遇到以下错误：

  File "/home/amarjeets/Workspace/View/mainMenu.py", line 2, in <module>
    from ContentLayout.UserInput.TextInputLayout import TextInput
ModuleNotFoundError: No module named 'ContentLayout'

回溯（最近一次呼叫最后一次）：
文件“app.py”，第1行，在
从View.Main菜单导入菜单设计
文件“/home/amarjeets/Workspace/View/mainMenu.py”，第2行，在
从ContentLayout.UserInput.TextInputLayout导入TextInput
ModuleNotFoundError:没有名为“ContentLayout”的模块

我尝试将

\uuuu init\uuuuuuuy.py

文件放入

视图

，

内容布局

和

用户输入

文件夹，但所有排列/组合仍然存在相同的错误
在python中导入一个给定项目文件夹/文件结构（如我的项目文件夹/文件结构）的模块/类/函数时，是否需要遵循任何规则或一般准则？
及

如果我在ContentLayout文件夹中还有一个文件，即

consolidatedLayout.py

，以及所有其他文件，那么如何从

ButtonLayout.py

或

TextInputLayout.py

中导入模块，我有以下文件夹结构：

C:.
│   app.py
│   __init__.py
│
└───View
    │   MainScript.py
    │   __init__.py
    │
    └───Folder1
            sub1.py
            __init__.py

app.py

：

from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

MainScript.py

：

from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

sub1.py

：

from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

当我启动app.py时，这是输出：

123
printed inside of sub1.py

请注意，

MainScript

内部的导入是

from View.Folder1.sub1 import printIt

，其中

View

是“上方”文件夹，它被视为导入的

模块。
我有以下文件夹结构：
C:.
│   app.py
│   __init__.py
│
└───View
    │   MainScript.py
    │   __init__.py
    │
    └───Folder1
            sub1.py
            __init__.py

app.py
：
from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

MainScript.py
：
from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

sub1.py
：
from View.MainScript import Test

print(Test.x)
Test.p()

from View.Folder1.sub1 import printIt

class Test:
    x = 123
    p = printIt

def printIt():
    print("printed inside of sub1.py")

当我启动app.py时，这是输出：
123
printed inside of sub1.py

请注意，MainScript
内部的导入是from View.Folder1.sub1 import printIt
，其中View
是“上面”的文件夹，这被算作您导入的模块。
我认为您必须在app.py
文件夹中有一个\uuuu init\uuuuuuuuuuuupy
，它才能工作。@hampusralson先生。。我也查过了。。。同样的错误。我甚至把\uuuu init\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuupy
放在所有文件夹中，但仍然是同一个错误。我认为你必须在app.py
文件夹中有一个\uuuuuuuuuuuuuuuuuuuuuuu。。我也查过了。。。同样的错误。我甚至把\uuuu init\uuuuu.py
放在所有的文件夹中，仍然是相同的错误。谢谢你的回复。因此，我必须从根路径（主线程启动的地方，即app.py）导入模块，或者我只需要从上面的一个文件夹导入？您必须将文件夹结构本身视为一个模块，并且必须指定要导入的文件的“方式”。因此，是的，您必须将其视为您的文件是从“根”文件夹导入的。谢谢您的确认。。。。这真的很有帮助。谢谢你的回复。因此，我必须从根路径（主线程启动的地方，即app.py）导入模块，或者我只需要从上面的一个文件夹导入？您必须将文件夹结构本身视为一个模块，并且必须指定要导入的文件的“方式”。因此，是的，您必须将其视为您的文件是从“根”文件夹导入的。谢谢您的确认。。。。这真的很有帮助。
