How can I fix a conflicting peer dependency without running npm install?

Question

I have an old project that I created using create-react-app. I have a conflicting peer dependency regarding eslint that I've pasted below, along with my package.json. Running npm install isn't enough to fix it, so it seems I have to do it manually.

Could not resolve dependency:
peer @typescript-eslint/eslint-plugin@"2.x" from eslint-config-react-app@5.2.1
node_modules/eslint-config-react-app
  dev eslint-config-react-app@"^5.2.1" from the root project

Conflicting peer dependency: eslint@6.8.0
node_modules/eslint
  peer eslint@"^5.0.0 || ^6.0.0" from @typescript-eslint/eslint-plugin@2.34.0
  node_modules/@typescript-eslint/eslint-plugin
    peer @typescript-eslint/eslint-plugin@"2.x" from eslint-config-react-app@5.2.1
    node_modules/eslint-config-react-app
      dev eslint-config-react-app@"^5.2.1" from the root project

And here are the details of the package that I'd like to update to its latest version

"node_modules/eslint-config-react-app": {
      "version": "5.2.1",
      "resolved": "https://registry.npmjs.org/eslint-config-react-app/-/eslint-config-react-app-5.2.1.tgz",
      "integrity": "sha512-pGIZ8t0mFLcV+6ZirRgYK6RVqUIKRIi9MmgzUEmrIknsn3AdO0I32asO86dJgloHq+9ZPl8UIg8mYrvgP5u2wQ==",
      "dev": true,
      "dependencies": {
        "confusing-browser-globals": "^1.0.9"
      },
      "peerDependencies": {
        "@typescript-eslint/eslint-plugin": "2.x",
        "@typescript-eslint/parser": "2.x",
        "babel-eslint": "10.x",
        "eslint": "6.x",
        "eslint-plugin-flowtype": "3.x || 4.x",
        "eslint-plugin-import": "2.x",
        "eslint-plugin-jsx-a11y": "6.x",
        "eslint-plugin-react": "7.x",
        "eslint-plugin-react-hooks": "1.x || 2.x"
      }
    },

My thought process is that if I can update eslint-config-react-app, it'll no longer have dependent packages that don't work with the version of eslint I require. I've tried updating it to its latest version using --legacy-peer-deps, but that only updates the package(s) that's in node_modules/react_scripts.

My project has a ClientApp directory where I am trying to update these packages, and it's also where the package.json is. Is there a way of updating the package that's in just the node_modules folder?

Answer 1

I fixed it by typing in the latest version of eslint-config-react-app directly into my package.json, then deleting my node_modules folder and running npm install. I didn't know you could type in the packages, would've saved me a lot of time!
