Answer 1

run 'xattr' command in mac terminal，if result like bellow：

python version 2.7.10 can't run /usr/bin/xattr.  Try the alternative(s):

/usr/bin/xattr-2.6 (uses python 2.6)
/usr/bin/xattr-2.7 (uses python 2.7)

Run "man python" for more information about multiple version support in
Mac OS X.

you should creat a new soft link to '/usr/bin/xattr-2.7' run bellow commands:

cd /usr/bin
sudo rm xattr
sudo ln -s xattr-2.7 xattr

this solve my problem!
