运行adb出现这种错误：
bash: ./adb: No such file or directory
但adb确实存在。那说明你用的是64位的Linux，没装32位运行时库，安装：
$ sudo apt-get install ia32-libs
如遇到Package has no installation candidate
解决方法如下：
# sudo gedit /etc/apt/sources.list
添加源： deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse
# sudo apt-get update
# sudo apt-get install ia32-libs
