我尝试将 import "cloud.google.com/go/logging" 与此处找到的 go 示例代码一起使用：https://cloud.google.com/logging/docs/reference/libraries#using_the_client_library 。在 go1.15.6 中，我尝试了以下操作：

$ go get -u cloud.google.com/go/logging

# many errors about dependencies, so
$ go get -u github.com/google/go-cmp/cmp
$ go get -u golang.org/x/sync/semaphore

# then I can get through this one
$ go get -u cloud.google.com/go/logging

# for further amusement, these two fail with what seems to be a compiler error
$ go get cloud.google.com/go/storage
$ go get cloud.google.com/go/iam

# Then trying to build my code using Logging:
$ go build -i -v
cloud.google.com/go/logging/apiv2
# cloud.google.com/go/logging/apiv2

解决方案

感谢 jimb (https://stackoverflow.com/users/32880/jimb) 提供评论 在这个问题Problems installing GCP go library for logging（这个问题被那些不想提供帮助的人粗鲁地关闭）指向了这个答案的方向。

这里的问题是您没有使用模块，并且 google cloud 库仅支持这种方式。这意味着您根本不使用 go get ...，尽管文档位于 https://cloud.google.com/logging/docs/reference/libraries#client-libraries-install-go 。相反，首先创建这个 go.mod 文件：

module example.com/mymod

go 1.15

require (
    cloud.google.com/go/logging v1.1.2
)

然后，运行 go build -i -v 这将安装所有必需的模块。
