How to fix npm ERR! invalid: [email protected], required peer react@^16.0.0 || ^17.0.0 in npm

What this error means

Peer dep invalid means the installed version does not satisfy the peer range declared by the dependent package, risking runtime incompatibility.

Typical symptoms

• npm WARN peer dep invalid: <pkg>@<installed> requires <range>
• Plugin fails at runtime due to API mismatch

Common causes

1. Installing newer major of a peer than the plugin supports
2. Lockfile drift after upgrades
