so I got a new pc and I wanted to pass my angular project through github.
I used 1.npm i 2.npm i @angular/cli@latest -D 3. ng update
And Everytime I'm trying to run the project with ng s it keeps sending me this error:
This version of CLI is only compatible with Angular versions ^9.0.0-beta || >=9.0.0 <10.0.0,
but Angular version 8.2.14 was found instead.
Please visit the link below to find instructions on how to update Angular.

I tried using the instructions at the link.
This is my Angular version when typing ng --version:
Angular CLI: 9.0.1
Node: 12.16.0
This is the package.json:

I'm really clueless about it... I would be glad if you help me.
The version of Angular you are using in the project is lower than the version required for the latest version of Angular CLI. I would recommend you downgrade Angular CLI to 8.3.25
npm uninstall -g @angular/cli npm cache clean npm install -g @angular/cli@8.3.25And change the version of Angular CLI in your devDependencies:
npm install -D @angular/cli@8.3.25First step install Angular globally.
npm install -g @angular/cli@latest
Run Update command to get a list of all dependencies required to be upgraded.
ng update
Next Run update command as below for each individual Angular core package
ng update @angular/cli @angular/core
If you want to force the changes use: –force and –allow-dirty flags command additionally to fix all other pending issues.
ng update @angular/cli @angular/core --allow-dirty --force
This is worked for me
Delete folder node_modules and package-lock.json
then execute: "npm install"
in short:
go to project directory in terminal/command prompt and execute following commands
rm -fr ./node_modules
rm -fr ./package-lock.json
npm install
ng serve -o
