Yarn install issues

1. **Check `yarn.lock` and `package.json`**:
– Make sure that `yarn.lock` and `package.json` are not out of sync. Sometimes an outdated lock file can cause issues. You can try deleting both the `yarn.lock` file and `node_modules` folder, then running `yarn install` again.

rm -rf node_modules yarn.lock
     yarn install

2. **Check the Yarn version**:
– Sometimes, issues arise due to bugs or incompatibility with certain versions of Yarn. Run `yarn –version` to check your Yarn version, and update if needed:

yarn set version latest

3. **Ensure correct permissions**:
– Check if you have the proper write permissions for the `node_modules` directory and your project files. If you're on Windows, ensure that no other processes (like an IDE or another package manager) are locking files.

4. **Check for error messages**:
– Check the console for any warnings or errors during the install process. If Yarn is silently failing, it might not be adding the dependencies.

5. **Clear Yarn cache**:
– Sometimes a corrupted cache can cause issues. Clear the cache and try again:

yarn cache clean
     yarn install

6. **Verify `package.json` dependencies**:
– Ensure that the dependencies in `package.json` are correctly listed and formatted. If any dependencies are missing or malformed, `yarn install` will not add them.

7. **Run Yarn in a clean environment**:
– If you're using Docker or any containerized environment, ensure that Yarn is installed and running correctly inside the container. You may need to restart your Docker container or rebuild the image if something went wrong during the setup.

8. **Check the Node.js version**:
– Ensure that the Node.js version you're using is compatible with the packages in your `package.json`. Some dependencies may have issues with certain Node.js versions.

Let me know if any of these suggestions help or if you need further assistance.

1. **Git Repository Access Issue** (`Failed listing refs`):
– Yarn is failing to access the Git repository for the `prcomboselect` package. This could be due to a problem with your SSH key configuration or repository access permissions.

**Possible Solutions**:
– Ensure your SSH keys are properly set up and added to your GitHub account. You can test your SSH access by running:

ssh -T git@github.com

If this doesn't work, you might need to set up your SSH keys.

– Alternatively, you can try switching the repository URL to HTTPS instead of SSH in your `package.json` if you have issues with SSH access:

"prcomboselect": "https://github.com/PebbleRoad/combo-select.git"

2. **Missing Package in Lockfile** (`sage@workspace:.: This package doesn't seem to be present in your lockfile`):
– This error suggests that there is a mismatch between the packages in your `node_modules` and the entries in your `yarn.lock` file, or a package is missing entirely.

**Possible Solutions**:
– Run the following to ensure all dependencies are properly installed and the lockfile is updated:

yarn install --force

This will reinstall all dependencies and regenerate the lockfile, which might resolve the inconsistency.

– If the issue persists, check your `package.json` for any missing dependencies or incorrect references. Also, verify that your project setup includes the necessary packages for `sage` (which might be related to Sage 10 in the context of WordPress).

– If `sage` is part of a workspace, make sure that your workspace configuration is correct.

Try these steps and let me know if the issue persists or if you encounter any further errors.
