求助帖：mac端在学习以太坊源代码时遇到问题 ld: symbol(s) not found for architecture x86_64

[zyymmm96128]

我使用的是mac终端，先通过git clone https://github.com/ethereum/go-ethereum.git将远端以太坊代码下载下来，然后按网上所找到教程的提示，进入了go-ethereum文件夹，运行了make geth命令，出现如下问题：

ld: warning: ld: warning: ignoring file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libpthread.tbd, file was built for unsupported file format ( 0x2D 0x2D 0x2D 0x20 0x21 0x74 0x61 0x70 0x69 0x2D 0x74 0x62 0x64 0x2D 0x76 0x33 ) which is not the architecture being linked (x86_64): /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libpthread.tbdignoring file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd, file was built for unsupported file format ( 0x2D 0x2D 0x2D 0x20 0x21 0x74 0x61 0x70 0x69 0x2D 0x74 0x62 0x64 0x2D 0x76 0x33 ) which is not the architecture being linked (x86_64): /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd
