感谢您的评论，Dirk。你让我指向了正确的方向。我有两个旧版本的代码：pcre2和Rcpp。
这可能是安装PCRE2时出错(我使用"sudo port install PCRE2"进行了安装(，但当我；制造"；RInside的示例代码，我得到：
$ make rinside_sample0
clang++ -mmacosx-version-min=10.13 -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/include -I/Library/Frameworks/R.framework/Versions/4.0/Resources/library/RInside/include -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -Wall -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include rinside_sample0.cpp -L/usr/local/lib -F/Library/Frameworks/R.framework/.. -framework R -L/usr/local/lib -lpcre2-8 -llzma -lbz2 -lz -licucore -ldl -lm -liconv -L/Library/Frameworks/R.framework/Resources/lib -lRblas -L/Library/Frameworks/R.framework/Resources/lib -lRlapack /Library/Frameworks/R.framework/Versions/4.0/Resources/library/RInside/lib/libRInside.a -o rinside_sample0

ld: library not found for -lpcre2-8

$
我按照指示安装了最新版本的"；pcre2"；此处：https://izziswift.com/how-to-install-pcre-development-headers-on-mac-osx/.
我下载了"；pcre"；版本10.39，cd到该目录，运行：
./configure
make
make install
之后，RInside中的示例进行了编译，但我得到了一个运行时错误：
$ ./rinside_sample0
Error: function 'Rcpp_precious_remove' not provided by package 'Rcpp'
Execution halted
$
一些搜索表明，错误是由于运行旧版本(1.0.6(的"；Rcpp"；。我走进RStudio，输入"；install.packages("Rcpp"(；更新到1.0.7版本，现在一切都在运行！
希望通过这些步骤可以帮助其他遇到这些问题的人。
