Getting the below error while trying to run the command npm install after the angular migration to version 9.

Any help is appreciated. Thanks in advance

CodePudding user response：

The error message says that [email protected] requires zone.js@~0.9.1, however you've specified zone.js@~0.10.3 in your configuration.

Therefore, the solution is to downgrade the Zone.js version in your package.json:

{
  ...
  "dependencies": {
    ...
    "zone.js": "~0.9.1"
  }
}

Alternatively, if you insist on an incompatible version of Zone.js and want to override the corresponding dependency of jodit-angular, you can do that in your package.json:

{
  ...
  "overrides": {
    "jodit-angular": {
      "zone.js": "$zone.js" // means: use the version from my project instead of the one you want
    }
  }
}

One of the solution would be to remove both [email protected] and zone.js@~0.10.3 from your package.json and try npm install. After installation of npm, you can then add them manually to your project with the latest version.

npm i [email protected]
