npm ERR! peer dep missing: eslint-plugin-jsx-a11y@^2.2.3, required by [email protected]

As you see, I have installed [email protected] which is definitely fulfill ^2.2.3 required by

eslint-config-airbnb. However, it shows such error message. Any idea for solving such problem?

Answer 1

I have mis-understood the meaning of the ^ in version ^2.2.3.

After reading this link, ^2.2.3 means >=2.2.3 <3.X. That's why npm throws an warning.

Besides, below are links about peer-dependencies

• What's the difference between dependencies, devDependencies and peerDependencies in npm package.json file?
