Importerror: cannot import name ‘_unicodefun’ from ‘click’

When working with Python, it’s not uncommon to encounter an error “ImportError: cannot import name ‘_unicodefun’ from ‘click'”, which can occur when attempting to import the ‘click’ library in Python.

This error can prevent you from using ‘click’ in your Python code, which can be a problem if you rely on this library for command-line interface (CLI) development.

In this article, we’ll explore the potential causes of this error and provide some solutions that you can try to resolve it.

What is importerror: cannot import name ‘_unicodefun’ from ‘click’?

The “ImportError: cannot import name ‘_unicodefun’ from ‘click'” implies that the black module imports _unicodefun from the click package wherein it’s already removed in click version 8.1.0.

To fix the error, upgrade the version of the black module.

How this cannot import name ‘_unicodefun’ from ‘click’ importerror occur?

Let’s say you have a Python script that uses the ‘click‘ library to define command-line interfaces.

You have the following code in your script:

import click

def my_function():
    click._unicodefun()

When you try to run this script, you get the “ImportError: cannot import name ‘unicodefun’ from ‘click'” error message.

This error occurs because the ‘_unicodefun‘ module, which is a part of the ‘click’ library, cannot be found or imported.

Also, this could be due to a few reasons, such as:

  • The ‘click‘ library is not installed in your Python environment
  • The ‘click‘ library is installed, but the version is outdated
  • There is a version compatibility issue between the ‘click‘ library and other modules in your Python environment

Now, let’s proceed fixing this error

Solutions Importerror: cannot import name ‘_unicodefun’ from ‘click’

Here are the following solutions you can consider to fix the error.

Solution 1: Upgrade the Click module to Latest Version

The quickest and simple way to fix this error is to upgrade to the latest version.

Particularly, you can use any package manager to install or upgrade the Click package.

Whether of the two package manager pip or conda package manager, you can use it to install the same.

Here is the command you can try to run:

pip install click

Meanwhile when you are using conda package manager in installing this module.

Use the command as follows:


conda install -c anaconda click

When we wrote this article, the latest version of the click module is Version: 8.1.3. Therefore when you run the command above it will upgrade to Version: 8.1.3.

Solution 2: Downgrade Click module version

In case you cannot upgrade to the latest version, we can still install its package version in a more stable.

To fix this here is the command:

pip install -upgrade click==8.0.2

Solution 3: Update black module version

Another way to fix was introduced in black version 22.3.0, therefore to solve the error here are the following command.

pip install black click --upgrade
pip3 install black click --upgrade

# 📌 if you don't have pip in PATH environment variable
python -m pip install black click --upgrade
python3 -m pip install black click --upgrade

# 📌 py alias (Windows)
py -m pip install black click --upgrade

# 📌 for Jupyter Notebook
!pip install black click --upgrade

Alternatively, if you can’t install the latest version, install black version 22.3.0 instead.

Here is the command you can use:

pip install black==22.3.0
pip3 install black==22.3.0

# 📌 if you don't have pip in PATH environment variable
python -m pip install black==22.3.0
python3 -m pip install black==22.3.0

# 📌 py alias (Windows)
py -m pip install black==22.3.0

# 📌 for Jupyter Notebook
!pip install black==22.3.0

Solution 4: Check dependencies

The ‘click‘ library has some dependencies that need to be installed in your Python environment.

Make sure that all dependencies are installed and up to date.
You can check the ‘click’ library documentation for a list of dependencies and their versions.

Here’s an example code snippet that shows how to install the required dependencies:

pip install setuptools
pip install wheel
pip install cffi
pip install cryptography

Anyway here are some other fixed errors wherein you can refer to try when you might face these errors:

Conclusion

To conclude the error, ImportError: cannot import name ‘unicodefun’ from ‘click‘” occurs because the black module imports _unicodefun from the click package where it’s already removed in click version 8.1.0.

I hope this article has helped you fix the error.

Until next time! 😊

Frequently Asked Questions

What is Python ImportError and what causes it?

ImportError is raised when an import fails for any reason. The most specific subtype is ModuleNotFoundError (no such module). Plain ImportError typically means the module exists but a name inside it can’t be imported, e.g. ‘cannot import name X from Y’ (X was renamed, removed, or moved between versions of Y). Common with library version mismatches.

How do I fix ‘cannot import name X from Y’?

Three steps: (1) Check the library version: pip show Y. (2) Check the changelog of Y, X may have been renamed or removed in a recent release. (3) Either pin to an older Y version (pip install Y==1.x.y) or update your code to the new import path. Common 2025-2026 examples: Werkzeug url_decode removed, Pillow ANTIALIAS renamed to LANCZOS.

Why does the import work in REPL but fail in script?

Two reasons. (1) Different Python interpreter: REPL uses one Python, your script uses another. Run python –version both times. (2) Different working directory: REPL is started where you have access to local modules, script is run from a different cwd. Add the project path to sys.path or use python -m to run as a module.

How do I avoid circular import errors?

Circular imports happen when module A imports B and B imports A at the top level. Three fixes: (1) Move one import inside the function that uses it (lazy import). (2) Restructure code so A and B both import from a third module C. (3) Use TYPE_CHECKING for type-hint-only imports: if TYPE_CHECKING: from a import X.

Where can I find more ImportError fixes?

Browse the ImportError reference hub for 67+ specific fixes (Flask, Werkzeug, Django, ML library versions). For missing-module cases see ModuleNotFoundError. For Python setup help see Python Tutorial hub.
