How do I resolve peer dependency error: The package [email protected] does not satisfy its siblings' peerDependencies requirements

Question

I am getting this error when I run npm install. This seems because I am unable to satisfy some peer dependency but I am unsure which peer dependency I need to fix.

λ npm install

Answer 1

it worked when I:

---

1. updated npm "npm install npm -g"
2. downgraded react to; "react": "15.3.0"
3. cleared cache: npm cache clear
4. removed node_modules, rm -rf node_modules,
5. reinstalled node_modules, npm install.

Answer 2

For me npm install --legacy-peer-deps worked. Please read about this flag before using it.

--legacy-peer-deps: ignore all peerDependencies when installing (in the style of npm version 4 through version 6).

Answer 3

Just update node package manager (npm) to the latest version.

npm install npm -g

Answer 4

I was facing the same issue and I used following things:

1. Update the react version: "react": ^16.2.0" in package.json file
2. Delete the node modules by rm -rf node_modules
3. Run npm install
4. npm update

This worked for me.
