1. Download and extract the MacPorts 2.3.1 tarball. Either do so using your browser and the Finder, or use the given commands in a terminal window.

   $ curl -O https://distfiles.macports.org/MacPorts/MacPorts-2.3.1.tar.bz2
   $ tar xf MacPorts-2.3.1.tar.bz2

2. Afterwards, perform the commands shown in the terminal window. If you wish to use a path other than /opt/local, follow the instructions forinstalling multiple copies of MacPorts instead.

   $ cd MacPorts-2.3.1/
   $ ./configure
   $ make
   $ sudo make install

ok，大功告成！
