How can the issue of conflicting dependencies while deploying on Heroku be resolved, considering it seems impossible?

edit

Conflicting dependencies can be resolved on Heroku by carefully managing the dependency tree, keeping it as minimal and specific as possible. Here are some steps that can be taken to resolve conflicting dependencies:

1. Update dependencies: Check if the dependencies are up-to-date, and if new versions are available, update them.

2. Pin dependencies: Pin the dependencies to a specific version to avoid conflicts. This ensures that the same version of a dependency is used throughout the application.

3. Use isolated environments: Use isolated environments such as virtual environments or Docker containers to reduce the chance of conflicts. This allows multiple versions of the same package to coexist in different environments.

4. Specify exact versions: Instead of specifying a range of acceptable versions for a dependency, specify the exact version.

5. Remove unused dependencies: Remove unused dependencies from the project to simplify the dependency tree.

6. Use a package manager: Use a package manager, such as npm or pip, to manage dependencies and resolve conflicts automatically.

In cases where resolving conflicts seems impossible after trying these steps, it may be necessary to re-evaluate the dependencies and rebuild the application with a more compatible set of dependencies.
