Open the yarn.lock file: This file is typically located in the project's root directory.
Search for a specific package: Use the search feature in your text editor to input the package name you want to locate.
View the version information: In the yarn.lock file, each package entry includes a version number, which may also specify dependency version constraints. For example:
package-name@^1.0.0: version "1.0.2"
Here, package-name@^1.0.0 represents the requested version range, while version "1.0.2" indicates the actual installed version.
Confirm dependencies: If the package has dependencies on other packages, these dependencies are listed within the same entry along with their versions.
By following these steps, you can clearly identify the specific versions of each package and their dependency relationships. This is invaluable for debugging, upgrading, or maintaining consistent dependencies across your project.
