无法通过docker machine命令创建DigitalOcean水滴

我运行这个命令在DigitalOcean上创建一个新的液滴

docker-machine create --driver digitalocean --digitalocean-access-token xxxxxxx --digitalocean-size 1gb docker-app-machine

但未成功执行，这是日志：

但是，水滴已经创建，我可以在管理面板中看到它。你知道发生了什么事吗

码头工人： 版本17.03.1-ce-mac12（17661） 频道：稳定 d1db12684b

docker机器版本0.10.0，内部版本76ed2a6

在mac OS Sierra 10.12.3上运行似乎是docker machine 0.10.0版本的一个bug，您只需使用此命令（mac）将docker machine升级到0.12.1版本

可能的错误解释：

对于超级用户来说，也许是个更好的问题？你试过

sudo

吗？我试过sudo，但我得到了相同的错误

curl -L https://github.com/docker/machine/releases/download/v0.12.1/docker-machine-`uname -s`-`uname -m` >/usr/local/bin/docker-machine && \
  chmod +x /usr/local/bin/docker-machine
