# 3. INSTALL A GOOD VERSION OF Node.js AND npm
|
|
|
|
# 2019-01-16/29: @jvonau's PR #1403 moved install of Node.js (10.x for now) &
|
|
# npm to roles/nodejs/tasks/main.yml, triggered by roles/sugarizer/meta/main.yml
|
|
|
|
|
|
# 4. RUN "npm install" TO POPULATE ~35MB /opt/iiab/sugarizer-server/node_modules
|
|
|
|
# Re-running "npm install" USED TO fail on Raspbian 9 if not other OS's ?
|
|
# Strategies considered to avoid re-running it:
|
|
# OLD WAY 1: test & set flag node_modules_exists: True
|
|
# OLD WAY 2: "creates: ..." checks for non-existence of /opt/iiab/sugarizer-server-1.0/node_modules
|
|
# OLD WAY 3: set "register: git_sug_server_output" above, then as nec delete /opt/iiab/sugarizer-server-1.0/node_modules "when: git_sug_server_output.changed" and as nec run "npm install"
|
|
|
|
#- name: Check for /opt/iiab/{{ sugarizer_server_version }}/node_modules
|
|
# stat:
|
|
# path: "{{ sugarizer_location }}/{{ sugarizer_server_version }}/node_modules"
|
|
# register: nmtest
|
|
# ignore_errors: true
|
|
#
|
|
#- name: Set a flag to prevent re-running of "npm install"
|
|
# set_fact:
|
|
# node_modules_exists: True
|
|
# when: nmtest.stat is defined and nmtest.stat.exists
|
|
|
|
# NEW WAY BELOW: run "npm install --allow-root" every time, as modern versions
|
|
# of npm are incremental, with sanity checks (all 3 may work: but npm 6.2.0
|
|
# is better than 5.6.0. which is better than Ubuntu 18.04's 3.5.2).
|
|
|
|
# 2018-07-15: TK Kang & Holt confirmed sudo-driven "npm install" maxes out CPU
|
|
# for hours, on diff OS's using npm 5.6.0 and 6.2.0. Hours later you may get
|
|
# error: code EACCES, errno -13 (permission denied),
|
|
# "Missing write access to /opt/iiab/sugarizer-server-1.0/node_modules"
|
|
#
|
|
# SOLUTION: Implement '--allow-root --unsafe-perm=true' below, as is critical
|
|
# for 1st run of sudo-driven 'npm install' especially:
|
|
#
|
|
# ON DEBIAN: npm 5.6.0's --allow-root would be sufficient: causing creation
|
|
# of /root/.npm cache & lock files to owned by root:root instead of
|
|
# iiab-admin:iiab-admin...thus permitting it & IIAB installs to complete!
|
|
#
|
|
# ON RASPBIAN: npm 5.6.0's --unsafe-perm=true is *required* so that npm
|
|
# install actually finished (in about 5 minutes). It's possible we should
|
|
# remove --allow-root in favore of --unsafe-perm=true alone. But this needs
|
|
# testing on different Linuxes before proceeding.
|
|
#
|
|
# CLARIF 1: Something like 'chown -R root:root /root/.npm' would do the job,
|
|
# but cannot happen synchronously throughout the 1st run of 'npm install'
|
|
# (when it's needed!) Similar to what --allow-root does on Debian.
|
|
#
|
|
# CLARIF 2: Ubuntu 18.04 is currently unaffected due to its ancient
|
|
# npm 3.5.2, which instead uses /home/iiab-admin/.npm (which remains owned
|
|
# by iiab-admin:iiab-admin, even with '--allow-root', but thankfully still
|
|
# gets the job done, for now!)
