启动安卓手表模拟器失败

无法启动 Android Wear 的模拟器，但是手机和平板的模拟器可以启动。

--错误提示--
Cannot launch AVD in emulator.
Output:
emulator: WARNING: Classic qemu does not support SMP. The hw.cpu.ncore option from your config file is ignored.

Could not create temp file for system partition image: File exists

应该是最后一个系统文件创建失败导致的，但是我试了用管理员模式运行也是不行。
几个版本的镜像包都试过了。
