I'm trying to deploy my nodejs backend with codeship to elastic beanstalk. But everytime I get the following error:

bcrypt@1.0.3 install /tmp/deployment/application/node_modules/bcrypt
node-pre-gyp install --fallback-to-build

module.js:471
throw err;
^

Does anyone know how to fix it? been trying to fix it for couple days now, help is much appreciated!

You can see the github issue thread - https://github.com/kelektiv/node.bcrypt.js/issues/509. It seems that a lot of people are having the same problem as you. — Tsvetan Ganev, Dec 25 '17 at 22:46

Try to use bcrypt.js module instead of bcrypt which is an update/latest npm module.

Run npm install bcryptjs and then npm install

It should be npm install bcryptjs. Not npm install bcrypt.js – awebdev Sep 27 '20 at 22:34

First make sure you are not uploading the node modules folder and that the npm install command is working on the instance.

https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions

This problem is related to node-pre-gyp. A dependency of bcrypt.

For AWS Elastic Beanstalk When deploying to Elastic Beanstalk running Node 8.x, node-gyp doesn't have sufficient permissions to write to the tmp directory. bcrypt won't install and the application deployment will fail.

A workaround is to add a .npmrc file to the root of your project that will force node-gyp to run as root and allow the installation to complete. File contents for .npmrc:

# Force npm to run node-gyp also as root, preventing permission denied errors in AWS with npm@5 or @6
unsafe-perm=true

Another alternative (Perhaps the more right way) is to make .ebextensions file with code:

.ebextensions:00_change_npm_permissions.config:

  "/opt/elasticbeanstalk/hooks/appdeploy/post/00_set_tmp_permissions.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      chown -R nodejs:nodejs /tmp/.npm

This will give you sufficient access to run node-gyp

I am a bit flabbergasted as to how the other answers got more upvotes as it doesn't really apply to Elastic Beanstalk deployment flows. @Sai Kassam's answer is actually the closest thing to the correct answer and using a `.npmrc` file would solve this issue and allow the deployment flow for EBS to actually install bcrypt. @bytesbase, it may be worth exploring this as a solution to your problem and if it works, mark @sai Kassam's answer as the correct answer so others that face the exact same issue can benefit from it. — Awah Teh, Mar 24 '21 at 13:41

See this GitHub comment: https://github.com/kelektiv/node.bcrypt.js/issues/509#issuecomment-313693838

TL;DR: as a workaround run npm install bcrypt before running npm install

I created a .npmrc file with:

unsafe-perm=true

That seemed to have done it.

This is the same answer as above and doesn't add any value. – Arefe Sep 07 '21 at 00:49

Add bcryptjs dependency in your package.json and then npm install should work with all the dependencies.
