Size命令无法识别，以为安装正确

我正在 macOS 上工作并在 cc 上尝试了 size 命令

$ which cc
/usr/bin/cc

它无法正常工作

$ size /usr/bin/cc
size: /usr/bin/cc: unknown load command 0x32
size: /usr/bin/cc: unknown load command 0x32
size: /usr/bin/cc: unknown load command 0x32
size: /usr/bin/cc: file format not recognized

$ size /bin/ls
size: /bin/ls: unknown load command 0x32
size: /bin/ls: unknown load command 0x32
size: /bin/ls: unknown load command 0x32
size: /bin/ls: file format not recognized

并且尺寸是最新版本

$ size --version

但在 Centos 上

[root@iz2ze9wve43n2nyuvmsfx5z ~]# size /usr/bin/cc
   text    data     bss     dec     hex filename
 754853    8488   81856  845197   ce58d /usr/bin/cc

命令大小有什么问题？

$ file /usr/bin/cc
/usr/bin/cc: Mach-O 64-bit executable x86_64


$ size --help

  -v        --version                 Display the program's version

这有效

me at Max-2018 in ~/desktop
$ /Library/Developer/CommandLineTools/usr/bin/size /usr/bin/cc
__TEXT  __DATA  __OBJC  others  dec hex
4096    4096    0   4294979584  4294987776  100005000   


$ ls /Library/Developer/CommandLineTools/usr/bin | grep size
llvm-size
size
size-classic

size尽管按照您的说明安装了命令行工具包，但您似乎已经安装了 GNU 。尝试：/Library/Developer/CommandLineTools/usr/bin/size。

如果您的操作系统是 El Capitan (10.11) 或更高版本，则必须禁用啜（至少暂时）以便安装到 /bin、/sbin 和 /usr 等目录（但不是 /usr/local）。
