1. Perform the algorithm for resolving a path (step 2 above). Throw an error if this resolution fails.

For example, if the Haste package path for `'a/b'` is `foo/package.json`, perform step 2 as if _moduleName_ was `foo/c`.

1. Try resolving _moduleName_ under `node_modules` from the current directory (i.e. parent of [`context.originModulePath`](#originmodulepath-string)) up to the root directory.

1. Find the closest package to [`context.originModulePath`](#originmodulepath-string). If no package is found, return no resolution.
121

2. If the package does not declare both a `"name"` field and an `"exports"` field, return no resolution.

3. Split _moduleName_ into a package name (including an optional [scope](https://docs.npmjs.com/cli/v8/using-npm/scope)) and relative path.
123

4. If the package name does not match the current package's `"name"` field, return no resolution.
124

5. Get the result of [**RESOLVE_PACKAGE_EXPORTS**](#resolve_package-exports)(*context*, *packagePath*, *filePath*, *exportsField*, *platform*) against the current package's `"exports"` field.
125

1. If resolved path exists, return result.

2. Else, log either a package configuration or package encapsulation warning, then continue with normal resolution.
