I'm using the following version in my Angular project. When try to upgrade angular material library, it gives me the following error. Any help?


Angular CLI: 12.0.5Node: 18.12.1Package Manager: npm 8.19.2Angular: 12.0.5Package Version---------------------------------------------------------@angular-devkit/architect 0.1200.5@angular-devkit/build-angular 12.0.5@angular-devkit/core 12.0.5@angular-devkit/schematics 12.0.5@angular/cdk 12.2.13@angular/material 12.2.13@schematics/angular 12.0.5rxjs 6.6.7typescript 4.2.4

Why is This Error?

The error “Package ‘@angular/material’ is not a dependency” indicates a problem with npm (Node Package Manager) while attempting to resolve package dependencies during the execution of the “npm install” command.

Possible solutions for resolving this error include

Check Internet Connection: Ensure that your internet connection is stable. Sometimes, network issues can cause problems with resolving package dependencies.

Update npm: Ensure that you are using an up-to-date version of npm. You can update npm by running the following command:

npm install -g npm

Clear npm Cache: Clearing the npm cache might help resolve issues related to package resolution. Run the following command to clear the npm cache:

npm cache clean --force

Check Package Versions: Review your project’s package.json file to verify that the specified versions of packages are compatible. Adjust the versions if necessary.

Retry the Installation: After performing the above steps, try running the npm install command again.

If the issue persists, examining the specific error details provided by npm could offer more insights into the nature of the problem, allowing for a more targeted resolution. You can look for additional error messages or stack traces that might indicate which packages are causing the conflict or resolution failure.
