使用Rinno部署R Shiny独立应用时遇错误，求排查原因

Hey there! Let’s walk through the most common reasons you might hit that frustrating exclamation mark error when running setup_myapp.exe for your locally-run Shiny app built with Rinno:

• Missing or Mismatched R Dependencies
  Rinno packages your app alongside the R environment you used to build it. If any of your app’s required packages are missing, outdated, or you’re using a different R version than the one used for building, the installer can fail.
  Fix: Re-run install.packages() for every package your app relies on (don’t forget shiny itself!), ensure all packages are up to date, and rebuild the installer using the same R version.

• Incorrect App Directory Structure
  Rinno expects a standard Shiny app structure. If your ui.R/server.R/app.R files aren’t in the root of your project folder, or supporting files (like data, www assets) are misplaced, the setup process can get confused.
  Fix: Double-check your project has the right layout—main app files at the root, supporting assets in subfolders like www or data, no extra clutter that might interfere.

• Insufficient Permissions
  The installer might need admin rights to write files to system directories (like Program Files). Running it without elevated permissions can block file creation, leading to errors.
  Fix: Right-click setup_myapp.exe and select "Run as administrator" before launching.

• Antivirus/Firewall Blocking
  Custom-built executables often get flagged by security software as suspicious. Your antivirus or firewall might be blocking the installer from completing its work.
  Fix: Temporarily disable your security tools (for testing only!) and re-run the setup. If it works, add exceptions for both the installer and the final app executable in your antivirus/firewall settings.

• Errors in Rinno Configuration
  A typo or misconfiguration in your config.R file can break the installer. Common issues include incorrect app_dir paths, missing packages in the pkgs list, or invalid parameter values.
  Fix: Go through your config.R line by line. Verify app_dir points to your app’s folder, pkgs includes every required package, and all settings match Rinno’s documentation guidelines.
