go 获取返回 go：标志需要一个参数：-mod

Question

I have updated my go version from go1.12.4 to go1.13.4. I have created a project and initialized it with go mod init myproject creating a go.mod file with the information:

module myproject

go 1.13

When I try to download a dependency

 go get github.com/kelseyhightower/envconfig

It returns the following message:

go: flag needs an argument: -mod (from $GOFLAGS)
usage: go get [-d] [-t] [-u] [-v] [-insecure] [build flags] [packages]
Run 'go help get' for details.

I have reviewed the doc from golang modules wiki and from its github issues but couldn't find any solution.

I have downgraded to go1.12.13 version, but I still have the same problem.

My go env variables are:

GO111MODULE="on"
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/user/.cache/go-build"
GOENV="/home/usser/.config/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GONOPROXY=""

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build555598313=/tmp/go-build -gno-record-gcc-switches"

Thank you so much

I think the problem is with you IDE: Goland

Use go env in the terminal

Your will see a env value called GOFLAGS, that is the problem

Just unset the env value by using unset GOFLAGS
