There has been a breaking change in setuptools version 58.0.0.

The setuptools package has removed support for 2to3 during builds.

# Pin your setuptools version to <58.0

Open your terminal and run the following command.

Copied!
pip install "setuptools<58.0"
pip3 install "setuptools<58.0"

python -m pip install "setuptools<58.0"
python3 -m pip install "setuptools<58.0"
py -m pip install "setuptools<58.0"

Alternatively, you can avoid using packages that have use_2to3 in their setup parameters.

# Rerun the pip install command after pinning setuptools

Try to rerun your pip install command after pinning your setuptools version.

pip install mongoengine
pip3 install mongoengine

python -m pip install mongoengine
python3 -m pip install mongoengine
py -m pip install mongoengine

# Trying to install the latest version of the package

Alternatively, you can try to install the latest version of the package.

Copied!
pip install mongoengine --upgrade
pip3 install mongoengine --upgrade

python -m pip install mongoengine --upgrade
python3 -m pip install mongoengine --upgrade
py -m pip install mongoengine --upgrade

# Trying to install a prerelease version of the package

If that didn't help, try running the pip install command with the --pre option.

Copied!
pip install mongoengine --pre
pip3 install mongoengine --pre

python -m pip install mongoengine --pre
python3 -m pip install mongoengine --pre
py -m pip install mongoengine --pre

The --pre option makes it so pip includes pre-release and development versions of the package. By default, pip only finds stable versions.

The latest version of the package might not have use_2to3 in its setup parameters.

# Update your requirements.txt file

If you use a requirements.txt file, you can update it with the following command.

Copied!
pip freeze > requirements.txt

The command will update the contents of your requirements.txt file, so the next time you run the pip install -r requirements.txt, your project will be in a working state.

# Upgrade your version of pip

If the error persists, try upgrading your version of pip as well.

Copied!
pip install --upgrade pip "setuptools<58.0"
pip3 install --upgrade pip "setuptools<58.0"

python -m pip install --upgrade pip "setuptools<58.0"
python3 -m pip install --upgrade pip "setuptools<58.0"
py -m pip install --upgrade pip "setuptools<58.0"

Try to rerun your pip install command after upgrading your version of pip.

Copied!
pip install mongoengine
pip3 install mongoengine

python -m pip install mongoengine
python3 -m pip install mongoengine
py -m pip install mongoengine

Make sure to replace the mongoengine package with the name of the package you're trying to install.
