AWS Elastic BeanStalk nodejs Deployment error

Question

I am stuck in a very weird issue from the last two days. I am trying to deploy my webpack nodejs app on AWS elastic beanstalk. The Environment Health changes from OK to Degraded. I have deployed it many times before but no such issue occurred. First of all, see the logs:

/var/log/eb-activity.log

/opt/elasticbeanstalk/containerfiles/ebnode.py --action node-install Activity execution failed, because: + /opt/elasticbeanstalk/containerfiles/ebnode.py --action npm-install

Now the error is of some node-gyp module and trust me I haven't heard it before. I am trying for a solution so that I can continue my work because this is really an embarrassing situation for me in front of my boss. Your help can get me out of this situation.

Thanks

I had the same problems with various node modules. It was a simple toy project where I created the initial NodeJs express project using express init.

I found various posts about adding a file to the .ebextensions folder and ended up with this version:

Create a file called 01_delete_node_modules.config in the .ebextensions folder and add the following content:

files:
  "/opt/elasticbeanstalk/hooks/appdeploy/pre/49_delete_node_modules.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      sudo rm -rf /tmp/deployment/application/node_modules
