To install with pip through PyPI, it is recommend to use virtualenv (or module venv for modern pythons). The use of virtualenv prevents pollution of any system directories and allows you to wipe out the full installation simply by removing the virtualenv created directory (“WORK” in this example):

$ virtualenv WORK
$ source WORK/bin/activate
(WORK) $ python -m pip install scikit-quant
(WORK) $

If you use pip directly on the command line, instead of through python, make sure that the PATH envar points to the bin directory that will contain the installed entry points during the installation, as the build process needs them. You may also need to install wheel first if you have an older version of pip and/or do not use virtualenv (which installs wheel by default). Older versions of pip may also require the --user option, if you do not have write access to the installation directory. Example:

$ python -m pip install wheel --user
$ PATH=$HOME/.local/bin:$PATH python -m pip install scikit-quant --user

Alternatively, you can use pip from a conda environment:

$ conda create -n WORK
$ conda activate WORK
(WORK) $ python -m pip install scikit-quant
(WORK) $
