Apple M1在从源代码安装时，在R包的预期库中没有png.h。
我用自制软件安装的
> brew install libpng其将png.h安装到，
/opt/homebrew/Cellar/libpng/1.6.39/include/libpng16/png.h符号链接为，
/opt/homebrew/include/png.h当我尝试安装软件包时，
install.packages("ggiraph", type = "source")我得到了错误，

如果你是从CRAN二进制文件而不是从源代码安装R，那么你应该使用here托管的二进制文件安装外部库，而不是从Homebrew安装，Homebrew的二进制文件可能与CRAN的不兼容。在你的情况下，我会尝试：
这应该在
/opt/R/arm64下安装libpng，其中CRAN将R配置为查找外部库。您可以使用R CMD config查询默认搜索路径：如果您坚持使用Homebrew安装，则通过设置
PKG_CPPFLAGS和PKG_LIBS添加到默认搜索路径：
