如何在mongodb网格fs中导入库？

Question

我正在尝试在MongoDB网格fs上工作，我是新手。我找到了在线资源，使gridfs在golang中工作，我找到了这篇文章。当我获取代码并尝试运行它时，它给了我以下错误。

错误

could not import go.mongodb.org/mongo-driver/mongo/gridfs (cannot find package "go.mongodb.org/mongo-driver/mongo/gridfs" in any of 

/usr/local/go/src/go.mongodb.org/mongo-driver/mongo/gridfs (from $GOROOT)

/home/bilal/go/src/go.mongodb.org/mongo-driver/mongo/gridfs (from $GOPATH))

图书馆

"go.mongodb.org/mongo-driver/bson"

"go.mongodb.org/mongo-driver/mongo"

"go.mongodb.org/mongo-driver/mongo/gridfs"

"go.mongodb.org/mongo-driver/mongo/options"

这四个库给了我这个错误。但我只举了一个错误的例子。

似乎您尚未正确安装依赖项。首先，您需要按照参考文章中所述设置项目。go mod init PROJECT-NAME然后，您需要安装依赖项，如最初链接的文章中所述：go get go.mongodb.org/mongo-driver/mongo go get go.mongodb.org/mongo-driver/mongo/gridfs
