It's still an old version , Did you not update the environment variables or did not install successfully at all . Look at that brew install A reminder of ( If there is a problem when compiling the software, you must see the error message !!!)

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/autoconf
Target /usr/local/bin/autoconf
already exists. You may want to remove it:
  rm '/usr/local/bin/autoconf'

To force the link and overwrite all conflicting files:
  brew link --overwrite autoconf

To list all files that would be deleted:
  brew link --overwrite --dry-run autoconf    

Black and white , Although the compilation was successful , But the link failed .( That is, the creation of a soft chain fails ), Because of the old version of autoconf Occupy the pit ,brew Also dare not casually overwrite
See which files to overwrite
