ModuleNotFoundError: No module named 'skbuild' in Python #

To solve the Python "ModuleNotFoundError: No module named 'skbuild'", run the pip3 install --upgrade pip command to upgrade pip and then install the scikit-build module by running the pip install scikit-build command.

no module named skbuild

Open your terminal in your project's root directory and install the scikit-build module.

shell
# ✅ First upgrade pip pip3 install --upgrade pip # ✅ if you get permissions error, run with sudo sudo pip3 install --upgrade pip # 👇️ in a virtual environment or using Python 2 pip install scikit-build # 👇️ for python 3 (could also be pip3.10 depending on your version) pip3 install scikit-build # 👇️ if you get permissions error sudo pip3 install scikit-build # 👇️ if you don't have pip in your PATH environment variable python -m pip install scikit-build # 👇️ for python 3 (could also be pip3.10 depending on your version) python3 -m pip install scikit-build # 👇️ for Anaconda conda install -c conda-forge scikit-build
If you got the error when trying to install OpenCV, make sure to upgrade pip before installing opencv-python.
shell
# ✅ First upgrade pip pip3 install --upgrade pip # ✅ if you get permissions error, run with sudo sudo pip3 install --upgrade pip # ✅ Alternatives for upgrading pip # 👇️ On Linux or MacOS python -m ensurepip --upgrade # 👇️ using python 3 python3 -m ensurepip --upgrade # 👇️ On Windows py -m ensurepip --upgrade

Try running the pip install opencv-python command after upgrading pip and it should succeed.

After installing scikit-build, you can import from skbuild as follows.

main.py
from skbuild import setup print(dir(setup))

The Python error "ModuleNotFoundError: No module named 'skbuild'" occurs for multiple reasons:

  1. Not having the scikit-build package installed by running pip install scikit-build.
  2. Having an outdated version of pip.
  3. Installing the package in a different Python version than the one you're using.
  4. Installing the package globally and not in your virtual environment.
  5. Your IDE running an incorrect version of Python.
  6. Naming your module skbuild.py which would shadow the official module.
  7. Declaring a variable named skbuild which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

shell
python --version

get python version

For example, my Python version is 3.10.4, so I would install the scikit-build package with pip3.10 install scikit-build.

shell
pip3.10 install scikit-build # 👇️ if you get permissions error use pip3 (NOT pip3.X) sudo pip3 install scikit-build

Notice that the version number corresponds to the version of pip I'm using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip:

shell
# 👇️ make sure to use your version of Python, e.g. 3.10 python3 -m pip install scikit-build

If the "No module named 'skbuild'" error persists, try restarting your IDE and development server/script.

You can check if you have the scikit-build package installed by running the pip show scikit-build command.

shell
# 👇️ check if you have scikit-build installed pip3 show scikit-build # 👇️ if you don't have pip set up in PATH python3 -m pip show scikit-build

The pip show scikit-build command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

If you have multiple Python versions installed on your machine, you might have installed the scikit-build package using the incorrect version or your IDE might be set up to use a different version.

For example, In VSCode, you can press CTRL + Shift + P or ( + Shift + P on Mac) to open the command palette.

Then type "Python select interpreter" in the field.

python select interpreter

Then select the correct python version from the dropdown menu.

select correct python version

Your IDE should be using the same version of Python (including the virtual environment) that you are using to install packages from your terminal.

If you are using a virtual environment, make sure you are installing scikit-build in your virtual environment and not globally.

You can try creating a virtual environment if you don't already have one.

shell
# 👇️ use correct version of Python when creating VENV python3 -m venv venv # 👇️ activate on Unix or MacOS source venv/bin/activate # 👇️ activate on Windows (cmd.exe) venv\Scripts\activate.bat # 👇️ activate on Windows (PowerShell) venv\Scripts\Activate.ps1 # 👇️ install scikit-build in virtual environment pip install scikit-build

Your virtual environment will use the version of Python that was used to create it.

If the error persists, make sure you haven't named a module in your project as skbuild.py because that would shadow the original skbuild module.

You also shouldn't be declaring a variable named skbuild as that would also shadow the original module.

If the error is not resolved, try to uninstall the scikit-build package and then install it.

shell
# 👇️ check if you have scikit-build installed pip3 show scikit-build # 👇️ if you don't have pip set up in PATH python3 -m pip show scikit-build # 👇️ uninstall scikit-build pip3 uninstall scikit-build # 👇️ if you don't have pip set up in PATH python3 -m pip uninstall scikit-build # 👇️ install scikit-build pip3 install scikit-build # 👇️ if you don't have pip set up in PATH python3 -m pip install scikit-build

Try restarting your IDE and development server/script.

You can also try to upgrade the version of the scikit-build package.

shell
pip3 install scikit-build --upgrade # 👇️ if you don't have pip set up in PATH python3 -m pip install scikit-build --upgrade
If the error persists, I would suggest watching a quick video on how to use Virtual environments in Python.
