问题描述
我正在尝试通过自制软件安装JAGS，以便可以在R中使用它。每次安装时，我都会收到以下警告：
Warning: jags dependency gcc was built with a different C++ standard
library (libstdc++ from clang). This may cause problems at runtime.
然后，当我尝试在R中安装rjags时，出现以下错误：
configure: error: "cannot link to JAGS library in /usr/local/Cellar/jags/4.3.0_2/lib."
ERROR: configuration Failed for package ‘rjags’
* removing ‘/usr/local/lib/R/4.0/site-library/rjags’
我还尝试遵循JAGS 4.3.0自述文件中的安装指南。一旦我移至R，就会产生相同的错误。
Google搜索将我带到以下链接，这些链接似乎没有足够的相关性对我有帮助：
https://github.com/Homebrew/brew/issues/4904 https://github.com/Homebrew/homebrew-core/issues/32112 Link different C++ standard libraries on Mac OS X
这也是我的brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed,and which additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
/Users/aridf/opt/anaconda3/bin/icu-config

谢谢！
解决方法
根据https://gist.github.com/casallas/8411082，解决方案是将~/.R/Makedir更改为以下内容：
CC=clang
CXX=clang++
然后在R中重新安装软件包
