go: github.com/spf13/cobra/cobra upgrade => v0.0.0-20200826151851-02a0d2fbc9e6
go get github.com/spf13/cobra/cobra: ambiguous import: found package github.com/spf13/cobra/cobra in multiple modules:
        github.com/spf13/cobra v1.0.0 (/go/pkg/mod/github.com/spf13/[email protected]/cobra)

How can I do install binary to $GOPATH/bin?

Answer 1

Install the Cobra Generator

go get github.com/spf13/cobra/cobra

More Info: https://github.com/spf13/cobra/blob/master/cobra/README.md

Answer 2

Actually go get -u github.com/spf13/cobra/cobra will install cobra into $GOPATH/bin/cobra you can check it by:

ls $GOPATH/bin/cobra

But when you run:

cobra

in your environment must be specified $PATH which leads to $GOPATH/bin, to do that you must run:

export PATH=$PATH:$GOPATH/bin

So now all must be ok.

PS: Add export PATH=$PATH:$GOPATH/bin to your ~/.bash_profile file so it will work after terminal restart.

Answer 3

for those who face this problems

you need to instal the cobra-cli NOT cobra

go install github.com/spf13/cobra-cli@latest

dont install with command like following

go get -u github.com/spf13/cobra@latest
