The issue is with MSbuild.exe. Do you know how it can be solved? I have installed both Visual Studio Community with Python extensions and Visual Studio Build Tools.

That looks like a problem compiling qdldl, a dependency of OSQP, which is a dependency of scikit-survival. However, it's hard to tell what could prevent it from finding the qdldl_types.h header. It's odd that pip doesn't choose a pre-compiled wheel of qdldl, which is available on pypi. Are you using Python 3.10? If yes, osqp/qdldl-python#19 could be relevant.

Thank you for the suggestion. I've tried to install cvxpy-base but nothing has changed.

conda packages for Python 3.10, including osqp and qdldl are now available. Please run
conda install -c sebp scikit-survival to install them.
