# Travis has custom python install earlier in $PATH even in Perl builds so need to install PyPI modules to non-system python otherwise they're not found by programs.
# Better than modifying $PATH to put /usr/bin first which is likely to affect many other things including potentially not finding the perlbrew installation first

# bootstrap commands:

# setup/bootstrap.sh
#
# OR
#
# Alpine:
#
#   apk add --no-cache git make && git clone https://github.com/harisekhon/devops-python-tools pytools && cd pytools && make
#
# Debian / Ubuntu:
#
#   apt-get update && apt-get install -y make git && git clone https://github.com/harisekhon/devops-python-tools pytools && cd pytools && make
#
# RHEL / CentOS:
#
#   yum install -y make git && git clone https://github.com/harisekhon/devops-python-tools pytools && cd pytools && make
