The Angular Compiler was found to be the incorrect class instance, causing issues with the project's build process

error snapshot

It appears that an incorrect instance of the Angular Compiler was detected, indicating the presence of multiple @ngtools/webpack packages. To verify this, you can use the command npm ls @ngtools/webpack and proceed to remove any duplicate copies.

Answer №1

Ensure that all angular packages in your project are updated to the same version to avoid compatibility issues. After updating the packages.json file with consistent versions, delete the nodes_modules directory and execute npm install.

When initiating the angular project, utilize npm start. If you opt for ng serve, it will use the global angular CLI version. To ensure consistency, make sure the global angular cli version matches the project's version.
