Ubuntu 下执行sh脚本 报错 ：No such file or directory

Ubuntu 下执行sh脚本 报错 ：-bash: ./build_xx.sh: /bin/sh^M: bad interpreter: No such file or directory

执行sh脚本报这个错，很是郁闷，但是目录下的确有这个文件。

原因：我的机器是64位的，需要32位的支持库。在Ubuntu 13.10及以后版本中依赖了 libncurses5:i386, libstdc+6：i386,and zlib1g:i386的包。

Android SDK requires 32-bit libraries. You probably are on 64-bit and need the 32-bit libs. Here are the troubleshooting directions from developer.android.com For Ubuntu 13.10 (Saucy Salamander) and above, install the libncurses5:i386, libstdc++6:i386, and zlib1g:i386 packages using apt-get: sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386 For earlier versions of Ubuntu, install the ia32-libs package using apt-get: apt-get install ia32-libs

所以执行如下命令进行安装包：

sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386 就可以了。
