我正在关注docker tutorial和第4部分：群体。输入db.collection.aggregate([
{ "$project": {
"hashmaps": { "$objectToArray": "$$ROOT" }
} },
{ "$project": {
"keys": "$hashmaps.k"
} },
{ "$group": {
"_id": null,
"count": { "$sum": {
"$cond": [
{
"$eq":[
{
"$ifNull": [
{ "$arrayElemAt": ["$keys", 1] },
0
]
},
0
]
},
1,
0
]
} }
} }
]);
后，我可以看到新创建的docker-machine处于'Stopped'STATE状态。如果我执行docker-machine create --driver virtualbox myvm1，则会收到以下错误，包括docker-machine restart myvm1：
VBoxManage: error: Failed to create the host-only adapter VirtualBox版本[(tfvm1) Progress state: NS_ERROR_FAILURE
(tfvm1) VBoxManage: error: Failed to create the host-only adapter
(tfvm1) VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
(tfvm1) VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface
(tfvm1) VBoxManage: error: Context: "RTEXITCODE handleCreate(HandlerArg *)" at line 94 of file VBoxManageHostonly.cpp
(tfvm1)
(tfvm1) This is a known VirtualBox bug. Let's try to recover anyway...
Error setting up host only network on machine start: The host-only adapter we just created is not visible. This is a well known VirtualBox bug. You might want to uninstall it and reinstall at least version 5.0.12 that is is supposed to fix this issue
]为vboxmanage --version;我试过卸载并重新安装VirtualBox。还尝试重新启动我的macOS High Sierra，并根据this link的建议安装Java v8，没有任何区别。
如果我尝试在VirtualBox GUI中启动VM，我会收到有关'VERR_VM_DRIVER_NOT_INSTALLED（-1908）'的错误，类似于this link中的问题。
我是Mac上的几个用户之一。我也试过以root用户身份运行'docker-machine create --driver virtualbox myvm1'，结果是一样的。
答案 0 :(得分：0)
我恢复了Virtualbox 5.1.28，让docker-machine再次运行
