Why do I always get this error when I try to install accumulation-tree? I need this for optbinning. A similar package would also be a solution.

  ERROR: Command errored out with exit status 1:

This error might be due to not having Cython installed. Alternatively, you can clone the repository from GitHub, remove the dependency tdigest from the list of install_requires in setup.py, and install from the source using python setup.py install.

Try running (in a terminal window)

xcode-select –install

(and clicking through dialog)

If that doesn't work try:

sudo xcode-select --reset

Several links show this problem in other contexts (e.g.)
