为何本地运行正常的blogdown网站在线无法更新？

It sounds like you've got the local preview working perfectly, but your live association website isn't picking up the changes you've made to the embedded homepage tweets and committee member info—super frustrating, I’ve been there! Let’s walk through the most common fixes for this scenario:

• Double-check your GitHub Pages deployment source
  Head to your website repo’s Settings > Pages section. Make sure the deployment branch matches where your built static files are stored. Most Hugo projects use a gh-pages branch for deployment (not the main branch where you edit content). If you’re using an automated workflow like GitHub Actions, confirm it’s set up to build the site and push the generated static files to the correct deployment branch.

• Verify you’ve built and pushed the static site files
  Local preview with blogdown::serve_site() runs a dynamic Hugo server, but the live site needs pre-built static files. Run blogdown::build_site() in RStudio to generate the public folder—this contains all the HTML, CSS, and JS that gets served online. If deploying manually, you need to push the contents of the public folder to your deployment branch. If using GitHub Actions, check the Actions tab for failed builds; there might be an error in the workflow preventing static files from being generated or pushed.

• Rule out caching issues
  Sometimes the problem is just cached content in your browser. Try a hard refresh (Ctrl+F5 on Windows/Linux, Cmd+Shift+R on Mac) or open the site in an incognito window. GitHub Pages also uses a CDN, so it might take 5-10 minutes for new changes to propagate across their servers—if you just pushed updates, give it a few minutes before troubleshooting further!

• Ensure Hugo version consistency
  Mismatched Hugo versions between your local machine and the deployment environment can cause unexpected issues. Run blogdown::hugo_version() in R to check your local version, then make sure your deployment setup (like GitHub Actions) uses the same version. For example, if you’re using an action like peaceiris/actions-hugo, you can specify the version in your workflow file with hugo-version: "X.Y.Z" (replace with your local version number).

If none of these steps resolve the issue, dig into the GitHub Actions logs (if applicable) for error messages—they usually point directly to what’s going wrong.
