$ go get failed because of "cli" package dependency

[kasumits]

When I tried to install this product with command $ go get github.com/motemen/blogsync, or $ cd ${GOPATH}/src/github.com/motemen/blogsync && go build -o blogsync after cloning this git repository, the following error has occurred, regardless of where the installation was tried, such as on my local machine(WindowsPowerShell) or on remote host(CircleCI-GoContainer).

I guess that the dependency between main.go and urfave/cli, which is mentioned as one of imported packages in main.go, leads this error. For your information, urfave/cli branched off in autumn 2019, and now there are two versions of that component, then import method written below may result in installation of urfave/cli/v1.

import (
	"github.com/urfave/cli"
)

cf. https://github.com/urfave/cli
cf. swaggo/swag#556

So I want to let you know the phenomenon, and I hope you would fix this issue.

Best regards.

May be resolved at #40. Please try it. Thanks for reporting!

Thank you for your quick acknowledgement and operation.

I've retried $ go get on remote host(CircleCI), then the most part of the problem has been treated successfully, but the rest hasn't been fixed yet.

#!/bin/bash -eo pipefail
go get github.com/motemen/blogsync
# github.com/motemen/blogsync
/home/circleci/go/src/github.com/motemen/blogsync/main.go:17:15: cannot use []cli.Command literal (type []cli.Command) as type []*cli.Command in assignment

Exited with code exit status 2

Another fix, maybe on ll.17-22 of main.go sited below, may be needed.

	app.Commands = []cli.Command{
		commandPull,
		commandPush,
		commandPost,
		commandList,
	}

So I want to ask a favor of you to reopen this issue.
Sorry for insufficiency of my previous indication.

Best regards.

Sorry for my incomplete fix. I’ll fix later.

I fixed code at #41 and blogsync now depends latest urfave/cli (v2.1.0).

However, due to this change, blogsync only works with go modules. Therefore, if you want to install blogsync with "go get", please set environment variable GO111MODULE "on" and get it with go 1.13 or later.

Alternatively, you can get built binaries from GitHub Releases and use that. If you just want to use the blogsync command, it is certain in many cases.
