Proposed fix: [Yarn Berry Plug'n'Play] '<pkg> tried to access <dep>, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.' — undeclared (hoisting-reliant) depe
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: If your code: add the dependency to package.json. If a third-party package: add it via packageExtensions in .yarnrc.yml (and upstream a fix). Alternatives: pnpMode: loose (still unsafe) or nodeLinker: node-modules.
Option: Declare the dependency (or extend the third-party package) [evidence: official_recommended_action]
Applies when: Strict PnP projects
Steps:
1. For your own code: yarn add <dep>
2. For a dependency: in .yarnrc.yml packageExtensions: { "<pkg>@*": { dependencies: { "<dep>": "*" } } } then yarn install
Expected: Require resolves
Option: Use node_modules linker [evidence: official_recommended_action]
Applies when: Toolchains incompatible with PnP
Steps:
1. Set nodeLinker: node-modules in .yarnrc.yml
2. yarn install
Expected: Traditional hoisted node_modules
