npm found incompatible peer ranges in your dependency graph. Choose versions that satisfy all peers or replace the conflicting package.

Quick fix

Fixes npm ERR! code ERESOLVE npm ERR! While resolving: package@version npm ERR! Could not resolve dependency: npm ERR! peer package@"^version" from other-package

npm install react@17 react-dom@17
# or upgrade the plugin
npm install some-plugin@latest
  1. Identify the incompatible peers
  2. Select compatible versions
  3. Refresh lockfile and reinstall
  4. Use overrides as a last resort
npm โ€” error
npm install react@17 react-dom@17
# or upgrade the plugin
npm install some-plugin@latest
npm ERR! code ERESOLVE
npm ERR! While resolving: package@version
npm ERR! Could not resolve dependency:
npm ERR! peer package@"^version" from other-package

What this error means

When multiple packages specify peers that cannot be satisfied simultaneously, npm stops with ERESOLVE. Typical with framework ecosystems (React/Angular/Vue) when plugins lag major versions.

Typical symptoms

  • ERESOLVE conflicting peer dependencies during npm install
  • Peer tree shows required vs installed versions
  • Install succeeds only with --legacy-peer-deps

Common causes

  1. Plugins pinned to older peer majors
  2. Lockfile contains versions outside peer ranges after upgrades
  3. Mixing prerelease and stable versions of core/peer packages

How to fix "npm ERR! code ERESOLVE npm ERR! While resolving: package@version npm ERR! Could not resolve dependency: npm ERR! peer package@"^version" from other-package"

1Identify the incompatible peers

Read the ERESOLVE output to see which package requires what. Note the required range and the installed version.

2Select compatible versions

Upgrade/downgrade the peer owner or the peer target so ranges overlap:

bash
npm install react@17 react-dom@17
# or upgrade the plugin
npm install some-plugin@latest
3Refresh lockfile and reinstall

Clear stale resolutions and reinstall:

bash
rm -rf node_modules package-lock.json
npm install
4Use overrides as a last resort

If you must force a peer, add an override and retest. Expect possible runtime breakage if the API changed.

Advanced notes

Keep ecosystem packages on the same major to avoid churn. In monorepos, align workspace peer targets centrally and upgrade lagging packages together.
