I have these versions:
Angular CLI: 8.3.19,
Node: 12.14.0.
Any Idea what causes this problem?
update @angular-devkit/build-angular version .
I had just created a new project and got this error. Since I had no legacy code I needed to work with and wanted to use the latest (9.0) version of Angular, I ran this command:
ng update @angular/cli @angular/core
and it fixed everything.
I had this error after npm audit found vulnerabilities in the version of @angular-devkit/build-angular that I was using. I ran npm audit fix which updated it to 0.900.2, but when I ran ng serve it gave the error quoted in the question.
I resolved it by downgrading to version 0.803.25. This was the highest version I could find which did not cause any errors when running ng serve. The vulnerabilities found by npm audit are resolved in this version.
This is the command I ran:
npm i @angular-devkit/build-angular@0.803.25
I was installing ngx-quill and faced the same issue. please make sure to check the supported versions.
For example - If you are using Angular 8, make sure you are installing the supported version. In case of ngx-quill, it will be npm install ngx-quill@5.2.0
It seems to be a problem with @angular-devkit/build-angular.
Try updating it by running
npm i @angular-devkit/build-angular
Or downgrading it by specifying a previous version, such as
npm i @angular-devkit/build-angular@0.803.24
running ng update will tell you what you need to update.
then run the commands and you will be good to go
I had the same issue in Ionic 4 after running "npm audit fix", but npm broke the whole versioning of the dependencies.
I tried doing most of the things listed here but it would fix one problem and create a new one. So the only solution that worked for me was manual dependency handling.
Check out what versions of each package you need in your package.json and package-lock.json (which package version do other packages depend on and expect to find in your project, mine were expecting about three total versions of some files), some will be shown as warnings in your cli after npm installing some packages, but not all will show so do best to manually check.
NB: I found package-lock.json easier for me to read but I would refer to package.json to make sure I was still on the right track.
For me the main package was Ionic itself (@ionic/angular-toolkit was the only package I could find that was connected to angular), so I looked at the version of angular it was expecting and downgraded to that. Then every other package that angular needed also had to be checked. It was a lot of work and spent half a day fixing but it solved all my issues.
Focusing on the angular package, I decided to
npm install @schematics/angular@8.0.0
That dependency, @schematics/angular@8.0.0, had the following dependencies;
The dependency, @angular-devkit/schematics@8.0.0 had the dependencies;
I did this for all the packages until I could build my app again. But you can just install in one go if you know the versions they require
npm install @schematics/angular@8.0.0 @angular-devkit/core@8.0.0 @angular-devkit/schematics@8.0.0
You can put all the packages in that npm install line if you already know for certain which other packages should be downgraded or upgraded to save time.
Hope this helps anyone who couldn't find a solution from the other comments.
Try deleting package-lock.json and reinstalling node_modules
I upgraded my ng8 project to ng9 with
ncu -u
This works for me:
ng update @angular/cli @angular/core --force
npm i @angular-devkit/build-angular@0.801.2
I have fixed this issue using the below command.
npm uninstall @angular-devkit/build-angular
npm install --save-dev @angular-devkit/build-angular
