我正在拼命地在 MacOS Big Sur 11.3 上安装png包R。

不幸的是，我对 libz.1.dylib 有疑问：安装似乎找不到它。

但是，我已经从/opt/local/lib/libz.1.dylibto/usr/lib和正确设置的/usr/local/lib目录复制DYLD_LIBRARY_PATH到它们。

这里的安装输出：

> install.packages('png')

我的文件~/.R/Makevars是：

VER=-9

CXX=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion -L/opt/local/lib

PKG_LIBS=$(PNG_LIBS) `libpng-config --static --ldflags`
PKG_CFLAGS=$(PNG_CFLAGS) `libpng-config --cflags`

我怎么能绕过这个问题？
