推荐答案

对我来说，此问题是随机出现的（以及多个类似的问题，例如如为nuget拒绝权限等。要解决此问题，请重新启动Visual Studio）对于 windows ，已通过重新启动docker服务并重新启动Visual Studio（2017）进行了修复。

For me, this issue appeared randomly (along with multiple similar issues, such as "permission denied for nuget" etc. To fix that, restart Visual Studio) For windows, it was fixed by restarting docker service and restarting Visual Studio (2017).

关闭Docker和Visual Studio

Winkey + R，键入services.msc

找到适用于Windows Service的Docker并重新启动它（通常仅重启Docker是不够的）

启动Docker和Visual Studio

Shut down Docker and Visual Studio

Winkey + R, type in services.msc

Find Docker for Windows Service and restart it (restarting Docker normally is not enough)

Start Docker and Visual Studio
