It seems that you are using Angular-CLI version 8, which packages that were meant to be used with version 7. How did you migrate to Angular CLI version 8? Did you use the Thanks |
@alan-agius4 I am using angular Angular 5

Hi, @angular/cli version 8 will only work with Angular version 8. Unfortunately Angular version 5 and CLI version 1, are not longer supported https://angular.io/guide/releases#support-policy-and-schedule I suggest you update to version 8 by running the update command via If the problem persists after upgrading, please open a new issue, provide a simple repository reproducing the problem, and describe the difference between the expected and current behavior. |
I can't update it Cannot update safely because packages have conflicting dependencies. Package @angular/platform-browser would need to match both versions "7.2.15" and "8.0.0, which are not compatible. ` |
Can you please share your package.json? |

i faced a same problem, i got error msg:"Could not find the implementation for builder @angular-devkit/build-angular:dev-server" after update @angular/cli version 8.0.0; |
It seems the ng update command does not work when using with v5.2. |
I also cannot update a version 5 project using ng update. I tried following the instructions at https://update.angular.io/#5.0:6.0 and got stuck when executing
Here's my package.json
The only sort of non-standard thing that is here that I'm aware of is that all of the dependencies are listed in the "dependencies" section, even those that are normally in the "devDependencies" section. This was done in order to satisfy requirements specified in https://www.codewithjason.com/deploy-rails-application-angular-cli-webpack-front-end/ which is used to allow an integrated rails / angular app to be deployed to Heroku. It would be great to have some suggestions on how to resolve this. |
@ryanmcfall see #14581 for a possible solution. |

What have worked for me was: 1.) Make sure your angular version starts with 7.2.15 (if not, you should install this version first)
|

I resolved issue, clear cache and npm install --save-dev build-ng-packagr |
npm uninstall @angular-devkit/build-angular |
npm audit fix worked for me |
I faced this issue after updating the typescript to latest version worked for me |
This one worked for me! but something strange now in my package.json: "@angular-devkit/build-angular": "^0.800.3", Is this normal? |

step 6 fails with:
I did a lot of weird stuff to get it working:
Seems to work now. Compiles the bundles and starts de app. |
Compiled successfully up until step 5th,
So used "ng update --all --force" command , it ran without a problem Before ng update the typescript version was 3.4.5 so I downgrade it with and it worked. |
I get this error even with a brand-new angular project. None of the above suggestions worked so far. |
I was struggling with this after upgrading to Angular 8. I had to do a few things including removing all the node_modules and then later: |
One important thing.......be VERY CAREFUL with running the command of "ng update --all" |
I got this error as well. What worked for me was running Hope this works for you too 😁 |
Thank you! The thing that worked for me while updating one of my projects was using your step 4 & 5. |
