I use Vue CLI for my project and I'm going to use the vue-chartjs plugin.
I used this guide for installation: https://vue-chartjs.org/guide/#installation but I got this error from npm:

OP fixed the issue by using npm i --legacy-peer-deps.

npm not installed latest version of package even after using caret(^)

I have added a package(X) as follows in package.json file
package(X): "^5.0.0"
now the latest version of package(X) is 5.0.1. According to my understanding this should install 5.0.1 but it installs version 5.0.0 itself.
Now I have multiple angular projects which are using package(X) and each of them have the same setup. What surprises me is that it works absolutely fine i.e installs version 5.0.1 in some projects and does not in some projects
Here is the info about package(x)
npm library info

It does depend on other packages' dependencies.
If there is a package that requires X to be exactly 5.0.0, then it will install 5.0.0 as it will satisfy ^5.0.0.
If there isn't one, then it will install whichever latest that will satisfy ^5.0.0 which is 5.0.1 in this case.

Seems like it's an ionic incompatibility with angular 10+
THIS WORKED FOR ME
npm uninstall #schematics/angular
npm install #schematics/angular#9.1.0

You may first proceed with npm uninstall #schematics/angular and TERMINAL informs that "removed XX packages and audited XXXX packages" etc, then you may implement npm install #schematics/angular#9.1.0.
Accordingly, ng add ngx-bootstrap provides:
✅️ Added "bootstrap
✅️ Added "ngx-bootstrap

In my case it was to have this:
"#ionic/angular-toolkit": "^2.3.3"
instead of "^2.2.0"
My Angular: 10.1.4.
I found this out by creating fresh Ionic project after upgrading Ionic CLI to newest.

The problem is schematics module incompatibility.
Find out the version of the #schematics/angular
node_modules/#schematics/angular/package.json/#_from
Find out the version of #schematics/angular which used in the #ionic/angular-toolkit module.
node_modules/#ionic/angular-toolkit/package.json
// package.json
"dependencies": {
"#schematics/angular": "^11.2.4",
}
Make sure the versions are matching.
If the versions do not match, then install the matching version of #schematics/angular.
Have an awesome day!

can you please try to run ng add #angular/pwa#13?

Try the code below
npm install #angular-devkit/schematics #angular-devkit/core #schematics/angular

This worked for me.
npm i --save-dev #nativescript/schematics

In my case, after failing with all kind of suggestions.
I update npm: https://www.hostingadvice.com/how-to/update-node-js-latest-version/
Later on Angular: https://update.angular.io/?v=13.0-14.0
and Ionic: https://ionicframework.com/docs/intro/upgrading-to-ionic-6
It works!!

Metadata version mismatch Angular 4 #ng-bootstrap

I am working on Angular bootstrap module. When I install the module using following commands npm install --save #ng-bootstrap/ng-bootstrap and import the module to the main app module. Then I rerun getting error for the following.

Question
Have to install angular latest version?.
If I install latest version can I run my Angular 4 project?
Why I'am getting this error?

The error is caused by the fact that ng-bootstrap module version that is installed has its metadata targeted for a higher version of Angular. To resolve this,
Find out which version of ng-bootstrap is currently installed by running
npm list ng-bootstrap
Run the following to see all the available versions of the ng-bootstrap node module.
npm show ng-bootstrap#* version
Pick one version lower than what is currently installed, and install it
npm install ng-bootstrap#x.y.z
*The x.y.z refers to version number.
Try npm start now, and see if it works.
If it doesn't, revert to one more lower version, and retry the above step of npm install.
Once it works - update package.json with the version number that resolved the issue so this issue doesn't appear again in the future. Let's say if version no. 1.3.0 solves the issue, then update the package json with.
"#ng-bootstrap/ng-bootstrap": "1.3.0"
Remove the caret (^) if it exists, to prevent auto-selecting the highest module version available.

This occurs because as of the latest version of #ng-bootstrap has issue.
I solved it by changing
"#ng-bootstrap/ng-bootstrap": "^1.0.0-beta.5",
in the package.json to
"#ng-bootstrap/ng-bootstrap": "1.0.0-beta.5",
You need specify the correct version in the package.json otherwise it will fetch the latest ng-bootstrap which has issue working with angular 4
