WARNING in ./node_modules/ng2-charts/fesm5/ng2-charts.js 230:54-72 "export 'ɵɵdefineInjectable' was not found in '@angular/core'
Update: May 2021
Recently I have used ng2-charts@2.4.2 in Angular v11 and it's working fine. You may try with the latest version
npm install ng2-charts@latest // it will automatically install latest versionOlder
ng2-charts v2.2.4 has this bug as lots of users are reporting that so down-grading to ng2-charts v2.2.3 is fine until it is fixed in the future releases.
npm install ng2-charts@2.2.3
Right, you have to do npm install ng2-charts@2.2.3 --saveAlso, check into your package.json for "ng2-charts": "2.2.3",I also faced same issue but previously I had "ng2-charts": "^2.2.3", so I removed caret (^). It means "Compatible with version" it will install major version. But use "Fixed version" if you don't want to change version of package on each installation.
