If gh-pages fails, you may find that you need to manually clean up the cache directory. To remove the cache directory, run node_modules/gh-pages/bin/gh-pages-clean or remove node_modules/.cache/gh-pages.
Here is what the above code is Doing:
1. The first line tells the script to use the node.js version specified in the .nvmrc file.
2. The second line tells the script to use the node_modules/.bin directory. This is where the gh-pages package will be installed.
3. The third line tells the script to use the gh-pages package to publish the contents of the dist directory to the gh-pages branch of the repository.
4. The fourth line tells the script to clean up the cache directory.
