bad interpreter in OS X about zhao

[gaocegege]

OS X下Python解释器默认是/usr/bin/python2.*什么的

多谢反馈 bug
俺手头没有 Mac OS 的环境，俺这个脚本是在 Linux 上开发的，没有考虑到对 Mac OS 的兼容性。
最好能找到某种“两边都兼容”的写法

我写了一个脚本，新建一个scripts目录，目录下新建build.sh：

#!/bin/sh

RED='\033[0;31m'
NC='\033[0m'

ROOT=$(dirname "${BASH_SOURCE}")/..

cd ${ROOT}/bin
if [[ $(which python1) ]]; then
    echo "Use python to build."
    $(which python) ./make.py $1
    cd - > /dev/null
    exit 1
fi
echo "${RED}Warnning${NC}: No python found, try to locate python2..."

if [[ $(which python2) ]]; then
    echo "Use python2 to build."
    $(which python2) ./make.py $1
    cd - > /dev/null
    exit 1
fi
echo "${RED}Warnning${NC}: No python2 found, try to locate python3..."

if [[ $(which python3) ]]; then
    echo "Use python3 to build."
    $(which python3) ./make.py $1
    cd - > /dev/null
    exit 1
fi
echo "${RED}Warnning${NC}: No python3 found... Abort."

用which python的方法来得到，三段逻辑重复，之后可以写的更加好看一点
