# You have to specify "--unsafe-perm" with npm install
# when running as root.  Failing to do this can cause
# install to appear to succeed even if a preinstall
# script fails, and may have other adverse consequences
# as well.
# This command will also cat the npm-debug.log file after the
# build, if it exists.
RUN npm install --unsafe-perm || \
