• Have you tried... installing the dependency? – Tomalak Commented Feb 17, 2017 at 2:42
• Does the WARN shows what I have to install exactly the peer ? I thought I already installed the eslint globally that will MEET the requirements. Am I wrong? – Liuuil Commented Feb 17, 2017 at 3:00

You can install eslint-config-airbnb-bundle. This is an unaltered Airbnb style guide config bundled with ESLint in a single package to solve some inconvenience with the installation (like unmet peer dependency warnings). You can install it globally as well:

npm i -g eslint-config-airbnb-bundle

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

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

I faced similar issue but found a solution to this issue. I thought its worth sharing.

To install the correct versions of each package related eslint config , You can run following mand :

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

You can get exact peer dependency which are listed by running above mand:

e.g about outputs ( as of answer's date ) will produce following :

{ 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' 
}

From above output you can exact idea about what dependencies to install for current ( latest build) .

If you want to install all dependencies in one go ( for Linux/OSX users only) Use below mand :

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

More details here.

From https://www.npmjs./package/eslint-config-airbnb

npx install-peerdeps --dev eslint-config-airbnb

I don't think you should install everything global. Try this:

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

Removing node modules (rm -rf node_modules/) and re-running npm install worked for me!!
