Report #104474

[bug\_fix] The engine "node" is incompatible with this module. Expected version ">=16". Got "14.21.3"

Upgrade Node.js to a version that satisfies the engine requirement \(e.g., use nvm to switch: \`nvm install 18 && nvm use 18\`\), or downgrade the offending package to a version that supports the current Node.js version. Alternatively, use \`yarn install --ignore-engines\` to bypass the check \(not recommended\).

Journey Context:
I cloned a modern project that required Node.js >=16, but my system had Node.js 14.x installed via the system package manager. Running \`yarn install\` immediately failed with the engine incompatibility error for every package that declared the engine requirement. I tried \`yarn install --ignore-engines\` but that felt unsafe. Instead, I installed Node Version Manager \(nvm\) and ran \`nvm install 18\`, then \`nvm use 18\`. After switching Node versions, \`yarn install\` succeeded. The root cause: Yarn reads the \`engines\` field in each package's \`package.json\` during installation and verifies that the current Node.js version matches the range. This is a safety mechanism to prevent using packages with runtime features that don't exist in older Node versions.
