'NPM Dependency Resolution Conflicts

When I run node install I get the following output:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve

and here is my package.json file:

{
    "name": "frontend",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
        "@emotion/react": "^11.9.0",
        "@emotion/styled": "^11.8.1",
        "@mui/icons-material": "^5.6.2",
        "@mui/material": "^5.6.3",
        "deck.gl": "^8.7.8",
        "react": "^18.1.0",
        "react-dom": "^18.1.0",
        "react-router": "^6.3.0",
        "react-router-dom": "^5.1.2",
        "react-scripts": "5.0.1",
        "react-transition-group": "^4.3.0"
    },
    "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test",
        "eject": "react-scripts eject"
    },
    "eslintConfig": {
        "extends": "react-app"
    },
    "browserslist": {
        "production": [
            ">0.2%",
            "not dead",
            "not op_mini all"
        ],
        "development": [
            "last 1 chrome version",
            "last 1 firefox version",
            "last 1 safari version"
        ]
    }
}

I have tried already npm install --legacy-peer-deps and npm install --force none of which changed the error message. I also tried npm install --legacy-peer-deps --save google-maps-react to see if I had to perform this individually for each package, no luck. I am aware that this error is relatively common, and it has something to do with the npm version and the dreaded breaking changes.

Does anyone know any other steps I can take?

Solution 1:[1]

I resolved the issue by running npm install --legacy-peer-deps after going from my pc's version of node 18.0.0 to the latest 16 LTS.

Solution 2:[2]

Found: [email protected] npm ERR! peer react@"^16.8.0 || ^17.0.0"

  1. npm config set legacy-peer-deps true
  2. npm install --save --legacy-peer-deps
  3. npm install --force
