我的 MacOS Mojave 10.14.5 和 Xcode 编译器有问题。准确地说，我正在尝试通过 Github 在 R 中安装一个包，而编译器正在为缺少 stdlib.h 而提示。这是错误:
有人可以向我解释如何解决这个问题吗？
clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include -fPIC -Wall -g -O2 -c bspline.c -o bspline.o

最佳答案
在终端 xcode-select --install 中运行为我解决了这个问题。
