ERROR: Could not build wheels for hdbscan, which is required to install pyproject.toml-based projects

Question

While trying to install hdbscan with pip I get this error.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for hdbscan Failed to build hdbscan ERROR: Could not build wheels for hdbscan, which is required to install pyproject.toml-based projects

Do you have any suggestions how I can fix this? I'm pretty new to python.

I also tried conda install hdbscan but then this error occures:

Answer 1

You need to install the python-dev package for the version of python you are using.

So on Ubuntu:

sudo apt-get install python3-dev

or, for example:

sudo apt-get install python3.10-dev
