Question

When I executed:

pip install xgboost

I got this:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/w4/w49s3mn91plbhyjwf8qjkpxc0000gn/T/pip-build-61dms1/xgboost/

I have tried several methods:

1. python ez_setup.py (the file downloaded from website)
2. pip install --upgrade setuptools
3. pip install distribute

But I still cannot solve this problem.

Answer 1

This is an old question, but I had an issue and realized pip was out of date. Solved my issue.

pip install --upgrade pip
pip install xgboost

Answer 2

This is how I installed it for Python 3.7:

brew install gcc@7
pip3 install
