Update to Angular 9 fails

Question

I use Angular 8 in my project and would like to upgrade to Angular 9.

I follow upgrade guide and when I run command: ng update @angular/core @angular/cli,

I get an error message:

An unhandled exception occurred: 403 Forbidden - GET https://registry.npmjs.org/@angular%2fcli

Update: 403 error is gone but now I get following errors:

Package "@angular/core" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "codelyzer" has an incompatible peer dependency to "@angular/core" (requires ">=2.3.1 <8.0.0 || >7.0.0-beta <8.0.0" (extended), would install "9.0.1").

Package "@angular/http" has an incompatible peer dependency to "@angular/platform-browser" (requires "7.0.4" (extended), would install "9.0.1").

SOLVED: I've added tslib to package.json

I can access link https://registry.npmjs.org/@angular%2fcli in browser and see a huge json file — aponski, Feb 17 '20 at 11:33

Experienced the same issue.

Was able to successfully update from Angular 7 to 8 using:

ng update @angular/cli@8 @angular/core@8

However, trying to update from Angular 8 to 9 using:

ng update @angular/cli@9 @angular/core@9

Gave me this error:

Package "@angular/compiler-cli" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/animations" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/common" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/compiler" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/core" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/forms" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/platform-browser" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/platform-server" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/router" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@angular/service-worker" has a missing peer dependency of "tslib" @ "^1.10.0".

Which I solved by adding the suggested version of tslib to devDependencies in package.json:

"devDependencies": {
    "tslib": "^1.10.0",
    ...
}

I was facing the same issue after the update to angular9. First I updated angular8 completely then update to angular9.

ng update @angular/cli@8 @angular/core@8

Second, I update the below command.

ng update @angular/cli@9 @angular/core@9

Please follow the link: How to Update till Angular9
