node.js - AWS Elastic Beanstalk ebextension not executing shell script to use npm install -

i need install separate framework created inside node js application running on elastic beanstalk.

i have tried putting scripts inside main package.json file permission errors when installs.

so created config file , tried running npm install container_commands. didn't want run npm said command missing. tried adding correct environment path variables npm, work when done manually through ssh, gave same error couldn't find npm command.

so finally.

i created bash script through ebextension installs application , run script container_commands.

the script gets created correctly never runs. if ssh instances , execute manually sudo works. app deploys without erros never seems execute script, know because node_modules folders never created.

i'm not sure errors in logs , when tried didn't find useful.

here ebextension:

files:     "/tmp/install_application.sh":         mode: "000755"         owner: root         group: root         content: |             #!/bin/bash             export path=$path:`ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin             eval "cd /var/app/current/library/server && npm install --production"             eval "cd /var/app/current && npm install --production"  container_commands:     00-install-application:     command: "sh /tmp/install_application.sh" 

i managed find answer this. had few issues script.

1. old scripts still in hooks folders previous attempts.
2. i firing script before project had unzipped yet or firing script after project had deployed.
3. i installing modules final destination /var/app/current being overwritten once deployed app installed.

here final script.

files:    "/opt/elasticbeanstalk/hooks/appdeploy/enact/00-install-application.sh":    mode: "000755"    owner: root    group: root    content: |        #!/bin/bash        path=$path:`ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin        cd "/tmp/deployment/application/library/server"        npm install --production
