How to Fix “AttributeError: module ‘enum’ has no attribute ‘IntFlag'”
Imagine that you are working on a python project, and you encounter an “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error. This could cause a significant delay in your project’s completion, especially if you do not know how to fix it.
Fret not, for in this article, we will provide you with several solutions that can help you fix this error.
Uninstalling the enum34 Module
The standard library for Python 3 has an enum module that has an IntFlag class that replaces the deprecated Flags mixin. However, many users still use the enum34 module that works with Python 2.
It provides the same functionality as the enum module in Python 3. However, if you try to run Python3 code that uses the enum module while the enum34 module is installed, the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error will occur.
Therefore, if you encounter this error, the first thing you should do is uninstall the enum34 module:
pip uninstall enum34
This command will remove the enum34 module from your machine. After doing that, you should try running your code again to see if the problem still persists.
Using IntEnum instead of Enum
If uninstalling the enum34 module did not fix the problem, you should try replacing Enum with IntEnum in your code. Enum is the base class for creating enumerations in Python 3, while IntEnum is a subclass that defines enumerations that have the properties of integers.
By using IntEnum instead of Enum, you can eliminate the chance of the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error occurring. To do this, you just need to modify the import statement in your code to:
from enum import IntEnum
Next, you should replace all instances of Enum in your code with IntEnum. After making these changes, run your code again to see if the error still persists.
Checking for a Local File Called Enum.py
Another possible cause of the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error is that you might have a local file named enum.py in your project directory. This file will be imported instead of Python’s built-in enum module.
To check if this file exists, navigate to your project directory and check if there is a file named enum.py. If you find such a file, you should rename it to something else to avoid conflicts with Python’s built-in enum module.
After renaming the file, run your code again to see if the error still persists.
Unsetting the PYTHONPATH Environment Variable
If none of the above solutions has fixed the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error, you should try unsetting the PYTHONPATH environment variable. This variable contains a semicolon-separated list of directories that Python looks at when trying to import a module.
If PYTHONPATH contains a directory containing an old or different version of the enum module, Python may try to import the wrong module, resulting in the AttributeError. To unset the PYTHONPATH environment variable, follow these steps:
1.
Open the Command Prompt or Terminal. 2.
Type the following command to display the current value of PYTHONPATH:
echo %PYTHONPATH%
3. If the output of the above command shows a directory containing an old or different version of the enum module, unset the variable by typing the following command:
set PYTHONPATH=
4.
After unsetting PYTHONPATH, navigate to your project directory and run your code again to see if the error still persists.

You can also join Python forums and communities to discuss your problems with fellow Python programmers.
Conclusion
In conclusion, encountering the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error can be frustrating, especially if you do not know how to fix it. However, by following the solutions provided above, you should be able to resolve the issue quickly and efficiently.
Always remember to check for local files, uninstall deprecated modules, and use the right import statements when working with enums. By employing these best practices, you can avoid errors and write efficient Python code.
In summary, encountering the “AttributeError: module ‘enum’ has no attribute ‘IntFlag'” error in Python can be frustrating, but there are several solutions to fix the problem. The article highlighted four possible solutions, including uninstalling the enum34 module, using IntEnum instead of Enum, checking for a local file called enum.py, and unsetting the PYTHONPATH environment variable.
Employing these best practices can help you avoid errors and write efficient Python code. Overall, it is important to understand how to work with enums in Python and always update your programming practices.
