Common Errors
QueryFailedError1 report"QueryFailedError" in Yarn often arises from incompatible or outdated dependencies within a monorepo, particularly when using Plug'n'Play (PnP). To resolve it, ensure that shared packages are correctly hoisted to the top-level node_modules and that all packages requiring those dependencies point to the hoisted versions. Consider updating Yarn to the latest version, clearing the Yarn cache, and regenerating the lockfile to reconcile dependency versions across the monorepo.
MaxRedirectsError1 reportThe "MaxRedirectsError" in yarn often occurs when yarn or npm encounters too many HTTP redirects while trying to download a package, typically due to misconfigured registries or network issues. To fix this, try clearing the yarn cache using `yarn cache clean`, and then explicitly set the correct registry using `yarn config set registry <your_registry_url>`, or try using npm with `npm config set registry <your_registry_url>`. If this doesn't work, investigate potential network proxy issues that might be causing the redirects.
UnsupportedProtocolError1 reportThe "UnsupportedProtocolError" in yarn often arises from outdated yarn versions or when yarn tries to access registries using unsupported protocols like `git+ssh`. Upgrade yarn to the latest version using `npm install -g yarn` or explicitly configure yarn to use `https` by setting the registry URL via `yarn config set registry https://registry.npmjs.org`. Also, inspect your `.yarnrc` file and dependencies' URLs for incorrect or git-based protocols and change these to `https`.
