Answer №1

If you're looking to streamline your ESLint setup, consider adding eslint-config-airbnb-bundle to your project. This comprehensive package includes an unaltered Airbnb style guide config bundled with ESLint for added convenience and eliminates any unmet peer dependency warnings that may arise during installation. For a hassle-free experience, you can also choose to install it globally:

npm i -g eslint-config-airbnb-bundle

To explore more options based on your coding needs, check out the following links:

Airbnb only: https://www.npmjs.com/package/eslint-config-airbnb-bundle

Airbnb + Standard: https://www.npmjs.com/package/eslint-config-airbnb-standard

Answer №2

Encountered a similar issue, but managed to find a solution that I believe is worth sharing.

If you need to install the correct versions of each package related to eslint config, simply execute the following command:

npm info "eslint-config-airbnb@latest" peerDependencies

By running the above command, you will receive a list of exact peer dependencies as shown below:

For example, the outputs at the time of this response indicate:

{ eslint: '^3.19.0 || ^4.3.0',
  'eslint-plugin-jsx-a11y': '^5.1.1',
  'eslint-plugin-import': '^2.7.0',
  'eslint-plugin-react': '^7.1.0' 
}

This output provides a clear idea of which dependencies to install for the current (latest build).

For Linux/OSX users who want to install all dependencies at once, use the following command:

(
  export PKG=eslint-config-airbnb;
  npm info "$PKG@latest" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs npm install --save-dev "$PKG@latest"
)

Answer №3

Visit this link for more information

Run the command: npx install-peerdeps --dev eslint-config-airbnb

Answer №4

Why not consider avoiding global installations for everything? Give this a try instead:

npm install --save-dev eslint eslint-config-airbnb eslint-plugin-jsx-a11y eslint-plugin-import eslint-plugin-react

Answer №5

After deleting the node modules folder using the command rm -rf node_modules/ and then running npm install again, everything started working perfectly!
