最近在寫 ruby，因為案子有切版本的需求就用了 rbenv 做不同版本環境切割

沒想到切一切爛掉所以重罐整個環境，結果就炸了

每次重灌時都跑出這種錯誤

linking shared-library libruby.2.6.dylib
Undefined symbols for architecture arm64:
  "__mh_execute_header", referenced from:
      _rb_dump_backtrace_with_lines in addr2line.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libruby.2.6.dylib] Error 1
make: *** Waiting for unfinished jobs....

參考幾篇文章後發現問題出在 xcode command line tool 14.0 在編譯 ruby 2.6.x 時會有問題

最後安裝 13.4 就搞定了，解法如下

solution

1. 找出 command line tool 安裝路徑 xcode-select -p

2. sudo rm -rf /path/to/commandlinetool

3. go to apple developer to download Command Line Tools for Xcode 13.4, link

4. install

就搞定拉
