ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers’

Hello Python Enthusiasts,

This article is about a common issue encountered while working with Python and its amazing libraries, “ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers’”. In the next sections, we will cover what the problem is, why it occurs, and how you can resolve it.

What is ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers’?

The error, “ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers'” occurs while importing the ‘BaseResponse’ from ‘werkzeug.wrappers’ in Python. Werkzeug is a WSGI utility library for Python widely used with the Flask web framework.

What causes the “ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers'” error?

This error is typically related to the software’s versioning issues. It appears when the Werkzeug library is updated to a version that doesn’t support the import of ‘BaseResponse’ anymore.

Code Examples

The code causing this error might look something like this:

from werkzeug.wrappers import BaseResponse

And the error message you’ll see would be something like:

ImportError: cannot import name 'BaseResponse' from 'werkzeug.wrappers'

How to resolve the “ImportError: Cannot import name ‘BaseResponse’ from ‘werkzeug.wrappers'” error?

There are two common ways to eliminate this error,

Solution 1:

Downgrade the `Werkzeug` package to a version where `BaseResponse` is available. It can be done by manually specifying the version in requirements.txt.



Then you have to run the following line in your terminal to install the specific version of Werkzeug you have specified.

pip install -r requirements.txt

Solution 2:

A better approach would be to upgrade your Werkzeug and Flask version so that they are synchronized.

You can upgrade them separately by using the commands,

pip install werkzeug --upgrade
pip install flask --upgrade

In both solutions, make sure to use a new virtual environment or delete your existing one before trying these solutions, to prevent any version conflict.


Q: Do I need to change my code after upgrading or downgrading Werkzeug?

No, you do not need to change your code after upgrading or downgrading.

Q: Can I avoid similar issues in the future?

Staying updated with the changes in the libraries and their compatibility issues can help with avoiding these types of errors.


Dealing with import errors can be a bit tricky, especially when you are not sure about the cause. But with a little bit of structured debugging and understanding the potential solution, you can easily overcome them. Remember, most software issues pertain to compatibility, so always pay attention to version numbers. Happy Coding!
