Core JS Postinstall Timing Out Amplify

Have you ever tried to install a package through npm and gotten stuck in the middle of it because the postinstall script is timing out? This can be a frustrating issue that can take up a lot of your time. In this post, I will share my personal experience with this issue and provide some possible solutions.

My Experience

When I was working on a project using Amplify, I encountered this issue while trying to install the core-js package. The installation would hang and eventually fail with a message saying, "Post-installation script failed". This was frustrating because I needed this package to continue working on my project.

Possible Solutions

After doing some research and testing, I found a few possible solutions that could help fix this issue:

1. Increase the timeout value.
2. Disable postinstall scripts.
3. Use an older version of the package.

1. Increase the timeout value

The first solution is to increase the timeout value of the postinstall script. You can do this by adding the following line to your package.json file:

"scripts": {
  "postinstall": "npm run build && NODE_OPTIONS=--max-old-space-size=4096 node_modules/.bin/amplify-post-install"
},
"config": {
  "max_old_space_size": 4096
},

This will increase the timeout value to 4096 MB, which should be enough for most installations. If this doesn't work, you can try increasing the value even further.

2. Disable postinstall scripts

If increasing the timeout value doesn't work, you can try disabling postinstall scripts altogether. You can do this by adding the following line to your package.json file:

"install": "npm install --ignore-scripts"

This will tell npm to ignore postinstall scripts when installing packages. Keep in mind that this may affect the functionality of some packages, so use this solution with caution.

3. Use an older version of the package

If all else fails, you can try using an older version of the package. You can do this by specifying the version number in your package.json file:

"dependencies": {
  "core-js": "2.5.1"
}

This will install version 2.5.1 of the core-js package instead of the latest version. Keep in mind that using an older version may affect the functionality of your project, so make sure to test everything thoroughly.

Conclusion

The core-js postinstall timing out issue can be a frustrating problem, but there are several solutions you can try to fix it. By increasing the timeout value, disabling postinstall scripts, or using an older version of the package, you can hopefully get past this issue and continue working on your project. Good luck!
