nextjs - 💡(How to fix) Fix `next info` unexpectedly interacts with Volta [1 comments, 2 participants]

Quick Fix Checklist for “next dev” Not Starting (reproduction‑template)

The minimal repo in the issue only shows a blank dev server. The most common cause is a stale build / mismatched package versions. The steps below clean the workspace, lock the Node version, and add a defensive next.config.js that forces the correct experimental flags.

1️⃣ Clean & Re‑install

# 1. Remove generated files & lockfiles
rm -rf .next node_modules package-lock.json yarn.lock

# 2. Pin a supported Node version (>=18, <21)
#    (use .nvmrc or engines field)
echo "18.20.0" > .nvmrc

# 3. Re‑install
npm ci   # or `yarn install` if you use Yarn

2️⃣ Add a Minimal next.config.js

Create/overwrite next.config.js at the repo root:

/** @type {import('next').NextConfig} */
const nextConfig = {
  // Force the current stable compiler
