无法在R Studio中连接ShinyApps.io发布账户求助

Hey there, let's work through this frustrating connection issue together. That rbind error you're seeing is almost always tied to version compatibility between your older R release (3.5.2) and the rsconnect package. Here's how to fix it step by step:

1. Downgrade rsconnect to a version compatible with R 3.5.2 #

Newer versions of rsconnect require R 3.6.0 or higher, which explains the matrix column mismatch error. Let's install a stable, compatible older version:

• First, uninstall your current rsconnect package:

  remove.packages("rsconnect")
  

• Then install version 0.8.25 (a known working release for R 3.5.x):

  # Use devtools if it's already installed and compatible with R 3.5.2
  devtools::install_version("rsconnect", version = "0.8.25")
  
  # If devtools fails, install directly from CRAN archive
  install.packages("rsconnect", repos = "https://cran.r-project.org/src/contrib/Archive/rsconnect/rsconnect_0.8.25.tar.gz", type = "source")
  

2. Clean up corrupted rsconnect configuration files #

Leftover or damaged config data can cause silent connection failures. Delete the rsconnect config directory:

• Windows: Navigate to C:\Users\<YourUsername>\AppData\Roaming\R\rsconnect and delete all files inside.
• Mac: Go to ~/Library/Application Support/R/rsconnect and clear the folder contents.
• Linux: Remove files in ~/.config/R/rsconnect.

3. Re-run the authorization command correctly #

Make sure you're using the exact command copied from your ShinyApps.io dashboard (Step 2 - Authorize Account). It should follow this format (replace with your actual credentials):

rsconnect::setAccountInfo(name = "your-shinyapps-username", token = "your-token-string", secret = "your-secret-string")

Double-check that all quotes are straight (not curly) and that you haven't missed any commas or parameter names.

4. Verify network connectivity (just to be thorough) #

Even though you disabled the firewall, confirm outgoing connections to ShinyApps.io work:

httr::GET("https://api.shinyapps.io")

If this returns a status code 200, your network isn't blocking the connection.

Why this works #

The rbind error occurs because newer rsconnect versions rely on R 3.6.0+'s updated namespace handling for S3 methods. By downgrading to a version built for R 3.5.x, you eliminate the matrix column mismatch that's breaking the authorization process.
