Sequelize migrations error while running in Elastic Beanstalk

问题

I'm trying to get Sequelize migrations to run on each deploy to Elastic Beanstalk.

I'm following the advice of the documentation, of other answers on Stack Overflow, and even a different project I've worked on in the past, and am using a .config file in my /.ebextensions folder:

container_commands:
    00_node_binary:
        command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
    01_npm_binary:
        command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
    03_db_migrate:
        command: ./node_modules/.bin/sequelize db:migrate
        leader_only: true

When I try to run it, I get this error:

ERROR   [Instance: i-06991b5ec3283038a] Command failed on instance. Return code: 127 Output: /bin/sh: ./node_modules/.bin/sequelize: No such file or directory.

What else do I need to do (either in .extensions, in .elasticbeanstalk file, or in EB's Software Configuration settings) so EB can find this module and run this command?

Note: The ls -td commands above produce this result in my previous project:

/opt/elasticbeanstalk/node-install/node-v6.9.1-linux-x64

And this result in the current project I'm having trouble with:

/opt/elasticbeanstalk/node-install/node-v10.17.0-linux-x64

回答1:

I resolve this error by running the command in .ebextension/config_file.sh

files:

"/opt/elasticbeanstalk/hooks/appdeploy/pre/config_file.sh":

mode: "000755"
owner: root
group: root
content: |
  #!/bin/bash
  
  curl --silent --location https://rpm.nodesource.com/setup_12.x | sudo bash -
  
  sudo yum -y install nodejs

---

then

run command on terminal in your app directory:

./node_modules/.bin/sequelize db:migrate

its works for me!!
