Report #102867

[bug\_fix] yarn error The engine "node" is incompatible with this module. Expected version "^14.17.0 \|\| >=16.0.0". Got "12.22.0"

Either upgrade Node.js to a compatible version, or pass the --ignore-engines flag to yarn to bypass the engine check \(not recommended for production\).

Journey Context:
A developer cloned a modern project that used React 18 and some new dependencies. They ran 'yarn install' and got an engine incompatibility error, because their system Node.js was v12.22.0, but the project's packages required Node v14.17\+ or v16\+. The developer tried to edit the package.json to remove the engines field, but yarn still checked the package's own engines. They then realized they could use nvm to switch to a compatible Node version, e.g., 'nvm install 16 && nvm use 16'. After that, yarn install succeeded. Alternatively, they could have used 'yarn install --ignore-engines' to skip the check, but that would risk running packages on unsupported Node versions. The root cause is that the 'engines' field in package.json is a contract that package managers enforce to prevent runtime failures.
