但是当我这样做：
$locate Magick-config /opt/local/bin/Magick-config /opt/local/share/man/man1/Magick-config.1.gz /opt/local/var/macports/software/ImageMagick/6.6.4-9_0+q16/opt/local/bin/Magick-config /opt/local/var/macports/software/ImageMagick/6.6.4-9_0+q16/opt/local/share/man/man1/Magick-config.1.gz /opt/local/var/macports/software/ImageMagick/6.6.5-0_0+q16/opt/local/bin/Magick-config /opt/local/var/macports/software/ImageMagick/6.6.5-0_0+q16/opt/local/share/man/man1/Magick-config.1.gz
有任何想法吗？
