Cannot install ccGains on MAC with Python 3.7.2

I have been unable to install ccGrains on MAC with Python 3.7.2

Here are the steps I am following: git clone https://github.com/probstj/ccgains.git cd ccgains pip3 install . I get the this error:

* USE_PKGCONFIG: False
.. ERROR:: Could not find a local HDF5 installation.
   You may need to explicitly state where your local HDF5 headers and
   library can be found by setting the ``HDF5_DIR`` environment
   variable or by using the ``--hdf5`` command-line option.

Looks like an error in installing the required 'tables' module. I have tried to set the HDF5_DIR env variable, using --hdf5, and brew install hdf5 But nothing helped in fixing this issue. Any ideas?

I had the same problem with same setup, but brew install hdf5 fixed it for me. After installing hdf5, did you try unsetting your environment variable and running pip install . again?

Is the error message the same after having installed hdf5 with brew?

Thanks Anson for your help! Mbenhalima, did it work?

thanks @anson-vandoren for the suggestions! this what finally worked for me:

brew install hdf5
brew install cairo
brew install pango
export HDF5_DIR=/usr/local/Cellar/hdf5/1.10.4/  # so the env variable should be the full path to the hdf5 package

I think I successfully loaded ccgains on my Linux machine but cannot get pip to work: tomf@tomVaio:/ccgains/ccgains$ pip install . Traceback (most recent call last): File "/usr/bin/pip", line 9, in from pip import main ImportError: cannot import name main I get the same error with tomf@tomVaio:/ccgains/ccgains$ pip install --user . as well as in one directory up: tomf@tomVaio:/ccgains$ pip install --user . To help figure out the problem here are the directory contents: tomf@tomVaio:/ccgains$ dir ccgains COPYING data examples README.md setup.py contributors.txt COPYING.LESSER docs MANIFEST.in run_tests.sh tests tomf@tomVaio:/ccgains/ccgains$ dir bags.py historic_data.py relations.py templates binance_util.py init.py reports.py trades.py I removed the ccgains directories and "git cloned" again but got the same error message with pip. There are no obvious errors that I can see during "git clone" but here is confirmation, in case that helps determine the problem: tomf@tomVaio:$ git clone https://github.com/probstj/ccgains.git Cloning into 'ccgains'... remote: Enumerating objects: 94, done. remote: Counting objects: 100% (94/94), done. remote: Compressing objects: 100% (37/37), done. remote: Total 564 (delta 57), reused 94 (delta 57), pack-reused 470 Receiving objects: 100% (564/564), 1.16 MiB | 0 bytes/s, done.
