Here are the errors I'm getting when I try to install my project:

Here is my package.json

  "dependencies": {
    "@angular/animations": "^6.1.0",
    "@angular/common": "^6.1.0",
    "@angular/compiler": "^6.1.0",
    "@angular/core": "^6.1.0",
    "@angular/forms": "^6.1.0",
    "@angular/http": "^6.1.0",
    "@angular/platform-browser": "^6.1.0",
    "@angular/platform-browser-dynamic": "^6.1.0",
    "@angular/router": "^6.1.0",
    "core-js": "^2.5.4",
    "rxjs": "~6.2.0",
    "sass": "^1.55.0",
    "zone.js": "~0.8.26"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.8.0",
    "@angular-devkit/build-ng-packagr": "^0.8.0",
    "@angular/cli": "~6.2.9",
    "@angular/compiler-cli": "^6.1.0",
    "@angular/language-service": "^6.1.0",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~8.9.4",
    "@typescript-eslint/eslint-plugin": "^4.31.2",
    "@typescript-eslint/parser": "^4.31.2",
    "codelyzer": "~4.3.0",
    "eslint": "^7.32.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.0.0",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.4.0",
    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~2.9.2"
  }

I understand at high level that different packages depend on different/conflicting versions, but I'd like to learn/understand exactly how to read that output. (E.g., which line corresponds to the package dependency, vs. its peer package dependencies.)

And, since the installation fails, I can't examine each package's package.json. So, where can I find the specific dependencies listed for a particular package?

Thanks in advance!

  • I also would like to understand how to read this file - for example, what does the nesting signify in the output. – Lukas Rossa Jan 18 '23 at 03:39

You can use npm install --legacy-peer-deps which ignores all peer dependencies when installing

But be cautious, this will bypass peerDependency auto-installation and will enhance the risk of introducing breaking changes
