Drush make command suddenly not working

[John Jones]

I've been using the following command for several years and today Pipelines is telling me "bash: drush: command not found". 

drush make -y --force-complete --no-gitinfofile --contrib-destination="profiles/ucd_drops" ../build/build-drops-pantheon.make

Am I missing something?

More info. Composer is not find drush. New location? Should I change the Path?

composer --version ; composer global require drush/drush:8.* ; export PATH=~/composer/vendor/bin:$PATH

Got composer to change to Version 1, still can't find drush.
