推荐答案

我也弄错了，我找到了答案；
您可以执行以下操作：

I'v got this wrong too,and i found the answer; you can do this :

第一
vmc删除您的应用程序

第二个 vmc push yourapp --runtime node08

也许您选择第一次将应用程序推送到云时，Node运行时的错误版本（node04，node06），服务器会记住您的选择。

maybe you choose the wrong varsion of the Node runtime (node04,node06) at the 1st time you push the app to cloud ,and the server remember your choice.
