I am using auth0-angular version 2.2.3 in my angular application. Locally the application is building correctly. When I build on github where the build is first doing an npm install, the following error is happening when building the appliction

Error: node\_modules/@auth0/auth0-spa-js/dist/typings/dpop/utils.d.ts:1:26 - error TS2307: Cannot find module ‘dpop’ or its corresponding type declarations.

I am not getting this error when building locally and I do not have the folder auth0-spa-js/dist/typings/dpop/ created in node\_modules folder. When I do an npm install locally I still do not have that folder. It looks like the npm install on github is getting a different version of auth0-spa-js even though I have version 2.2.3 of the auth0-angular in my packages.json file

Hi @judith1,

Welcome back to the Auth0 Community!

The error you’re seeing is caused by your GitHub build installing a newer version of the `@auth0/auth0-spa-js` library (a dependency of `auth0-angular`) than what you have on your local machine. The recommended solution is to use [`npm ci`](https://docs.npmjs.com/cli/v8/commands/npm-ci) instead of `npm install` in your GitHub workflow to ensure you get a reproducible build that respects your `package-lock.json` file.

The `npm ci` command performs a clean install by deleting any existing `node_modules` and installing dependencies based strictly on the `package-lock.json` file, guaranteeing a reproducible build.

You should use `npm ci` to ensure your GitHub build environment installs the exact same dependency versions as your local environment.

1. **Commit Your Lock File:** First, ensure that your `package-lock.json` file is committed to your Git repository. This file is the source of truth for your project’s dependencies.
2. **Update Your GitHub Workflow:** In your GitHub workflow YAML file (e.g., `.github/workflows/build.yml`), find the step that runs `npm install` and change it to `npm ci`.

If you have any other questions, feel free to reach out.

Have a good one,  
Vlad
