Golang 找不到提供 package {PACKAGE_NAME} 的模块：工作目录不是模块的一部分

Question

我想知道我的本地构建发生了什么？ 我想测试部署到 DEV 以解决问题，但我无法构建。 使构建-mac

env GOOS=darwin GOARCH=amd64 go build -ldflags "-s -w -X main.version=v1.0.20-16-ga0298c0 -X main.commit=a0298c0 -X main.branch=master -X main.buildDate=2020-05-20T11:12:36-0700" -o backend main.go
main.go:7:2: cannot find module providing package github.com/LF-Engineering/vulnerability-detection/backend/cmd: working directory is not part of a module
main.go:8:2: cannot find module providing package github.com/LF-Engineering/vulnerability-detection/backend/v2: working directory is not part of a module
make: *** [build-mac] Error 1

与构建 lambda 相同：

dep ensure -v
Building a staticlly linked binary...
env CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags "-s -w -X main.version=v1.0.20-16-ga0298c0 -X main.commit=a0298c0 -X main.branch=master -X main.buildDate=2020-05-20T11:26:15-0700" -tags aws_lambda -o backend_aws_lambda main.go
main.go:7:2: cannot find module providing package github.com/LF-Engineering/vulnerability-detection/backend/cmd: working directory is not part of a module
main.go:8:2: cannot find module providing package github.com/LF-Engineering/vulnerability-detection/backend/v2: working directory is not part of a module
make: *** [build_aws_lambda] Error 1```

I have done a clean build, removed vendor and re-tried.
Wonder if this is a go version problem? Recently updated:
```go version             
go version go1.14.3 darwin/amd64

解决与 package 设置和 vendor/Gopkg.toml/lock 位于父文件夹中相关的奇怪问题会很好。 我们应该使用 go mod，因为这将成为向前发展的标准，由于某种原因，我在使用目录结构时遇到了麻烦。

我之前发现了同样的问题，我解决了这个问题，改变环境变量， GO111MODULE从on到auto

打开 File/Preferences/Settings 并搜索“go tools env vars”单击“Edit in settings.json”并将 GO111MODULE 设置为auto （来自https 的说明：//dev.to/codeboten/disabling-go-modules-in-视觉工作室代码31mp ）
