r - 错误：dyn.load(file, DLLpath = DLLpath, ...) 中“roxygen2”的包或命名空间加载失败：

Question

roxygen2 似乎讨厌我。我将它安装在 R 3.6.3 OS X 10.14.6 中，它似乎运行良好：

> install.packages("roxygen2")
--- Please select a CRAN mirror for use in this session ---
trying URL 'https://ftp.osuosl.org/pub/cran/bin/macosx/el-capitan/contrib/3.6/roxygen2_7.1.0.tgz'
Content type 'application/x-gzip' length 955820 bytes (933 KB)
==================================================
downloaded 933 KB


The downloaded binary packages are in
    /var/folders/lm/c2f0w7g95q18plrh3bzc8klmfjh9r3/T//RtmphL5OZw/downloaded_packages

但是之后....

> library(roxygen2)
Error: package or namespace load failed for ‘roxygen2’ in dyn.load(file, DLLpath = DLLpath, ...):

 in /Library/Frameworks/R.framework/Versions/3.6/Resources/library/Rcpp/libs/Rcpp.so

我该如何修复？
