Mac系统RStudio加载tidyverse库失败求助（R新手）

Hey there, let's work through this issue together. The error you're seeing with Rcpp.so and the missing ___cxa_uncaught_exceptions symbol is almost always a compatibility problem between your older R version (3.6) and the newer system libraries on your Mac. Here are the most reliable fixes:

1. Update R to the Latest Version (Recommended) #

R 3.6 is quite outdated, and modern versions of tidyverse (and its dependencies like Rcpp) are built to work with newer Mac system frameworks. Updating R will resolve this library mismatch:

• Grab the latest Mac installer from the official R site, run it to replace your existing R 3.6 installation.
• Open RStudio again, then reinstall tidyverse with:

  install.packages("tidyverse")
  

• Now try loading it again with library(tidyverse)—this should work without issues.

2. Recompile Rcpp from Source (If You Can't Update R) #

If you need to stick with R 3.6 for some reason, forcing a source compile of Rcpp will let it adapt to your system's current libraries:

• First, remove the existing broken Rcpp installation:

  remove.packages("Rcpp")
  

• Then install Rcpp from source (this might take a minute as it compiles locally):

  install.packages("Rcpp", type = "source")
  

• Once done, try loading tidyverse again. The source-compiled Rcpp should now match your system's library symbols.

3. Verify System Compatibility #

Just a quick check: R 3.6 was designed for Mac OS X Mojave (10.14) or earlier. If you're running a newer system like Big Sur (11.x) or Ventura (13.x), the system-level C++ libraries have changed significantly, which is why the symbol is missing. In this case, updating R is the only long-term fix.
