Ada download

[sophia.adampour@gmail.com]

Hi! I get this error message when I try to download Ada on my MacBook Pro 2017 using "doinstall" on the terminal:

  This script is provided to simplify the installation of the
     x86_64-apple-darwin14.5.0
   binary version of the GNAT GPL Edition Ada (2012, 2005, 95, and 83)
   environment maintained by AdaCore. For information on commercial
   support please contact sales@adacore.com.

   This script will ask you how you would like to configure GNAT.
   Confirmation is required before any write action is taken.

   Please press RETURN to continue.

RETURN












    To install GNAT, you need to specify a base directory.
    All the files will be installed in subdirectories
    that are created under this directory.

    Important Note: You should not use ~ or ~username wildcards
    when specifying this directory name.

    In which directory do you want to install GNAT? [/usr/local/gnat]:
/usr/local/gnat2017


    The GNAT GPL Edition installation directory will be:
      /usr/local/gnat2017
    Is this correct ? Type 'Y' if so, otherwise type 'N' and you'll
    be prompted for another directory name.

    Do you want to continue ? [yY|nN]:

Y





   GNAT GPL Edition is now about to be installed in
      /usr/local/gnat2017.
   Type 'Y' if you want to proceed with installation or any other key
   if you wish to abort.

   Do you want to proceed with installation ? [yY|nN]:
