Go has a nice feature where you can go install <x> and it will download, build and install a binary.
For example, on my local windows PC, go install github.com/goreleaser/goreleaser will find the latest release for goreleaser, download, build and install it to my local binaries path.
I am working on a project where we would like to enable go install, but encounter a problem if the github repo name does not match the executable name. The GitHub CLI itself runs into the exact same problem:
Example:
go install github.com/cli/cli#latest
go: downloading github.com/cli/cli v1.14.0
go: github.com/cli/cli#latest: module github.com/cli/cli#latest found (v1.14.0), but does not contain package github.com/cli/cli
Is there a way to resolve this?
Update: I worked out that I could directly reference the package via it's sub directory. In my particular instance this works: go install github.com/OctopusDeploy/cli/cmd/octopus#latest
This is a bit unpleasant, but works correctly. It doesn't work for the github CLI because their go.mod has a replace directive in it :-(
Question: Can this be made nicer? Is there a way to put some sort of alias or configuration file so that go install github.com/OctopusDeploy/cli#latest can be used instead of go install github.com/OctopusDeploy/cli/cmd/octopus#latest ?

No. Dead simple.

So if I have a go module on my local filesystem, I can install a binary by running go install cmd/main.go and it will create a binary called $GOPATH/main as expected. Basically it behave the same as go build but copying the binary to $GOPATH.
However, when I try to install the same module on stored on Github, it fails:
go install github.com/sanbornm/go-selfupdate/cmd/go-selfupdate/main.go
no required module provides package github.com/sanbornm/go-selfupdate/cmd/go-selfupdate/main.go; to add it:
go get github.com/sanbornm/go-selfupdate/cmd/go-selfupdate/main.go
Instead, I need to call go install on the directory for it to properly work:
go install github.com/sanbornm/go-selfupdate/cmd/go-selfupdate
How do I reconcile this behavior difference?
So,I recently started following a video tutorial and i am fairly new to golang and tried installing the forked version of bolt db using
$ go get go.etcd.io/bbolt/...
Note : I want to use this specific version
but i am getting an error which says
go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd#latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'
I read a few GitHub issues which say that go get is deprecated so how do I resolve this ?
I also tried few other things such as
go install go.etcd.io/bbolt/...
Go modules are today's standard. Especially if you are new to Go; do not spend time on material that do not use (and teach) them.
Run go mod init yourproject
in your project repository root directory. This will create go.mod file.
Once you have that you can either:
import go.etcd.io/bbolt in source code and then run go mod tidy. Go tool will find and add module to your dependencies (go.mod file). This is described in Getting started tutorial.
run go get go.etcd.io/bbolt directly, that will update dependencies too.
Using Go Modules series explains workflow in detail and will be helpful when converting commands from an outdated material.
I'm trying to install my package using go install but I get this error message when running the command go install github.com/JoaoDanielRufino/gcloc/cmd/gcloc#latest:
go install: github.com/JoaoDanielRufino/gcloc/cmd/gcloc#latest: module github.com/JoaoDanielRufino/gcloc#latest found (v1.0.0), but does not contain package github.com/JoaoDanielRufino/gcloc/cmd/gcloc
I want the executable name to be gcloc.
Here is the current source code: https://github.com/JoaoDanielRufino/gcloc
Note: I've already tried go clean -modcache but it didn't work
As the main function of this package isn't on its root, you should pass the directory of the main package on your command.
So, your command will be:
go install -v github.com/JoaoDanielRufino/gcloc/cmd#latest
I came across a similar issue when I was trying to use go install to install the cloudflare/cf-terraforming tool on my machine. The documentation for this tool is not clear on the installation and I had to dig around to get this to work
Basically #Jictyvoo answer above sums it up, if the path is pointing to anything other than directory where the main.go file is sitting I got the error
Command: go install github.com/cloudflare/cf-terraforming#latest v0.8.0#latest
go: github.com/cloudflare/cf-terraforming#latest: module
github.com/cloudflare/cf-terraforming#latest found (v0.8.0), but does not
contain package github.com/cloudflare/cf-terraforming
when I switched to the below it worked fine for me:
Command: go install -v github.com/cloudflare/cf-terraforming/cmd/cf-terraforming#latest
This worked for me after checking the repo and realising that the main.go file was sitting in the cmd/cf-terraforming subdirectory
I am trying to Provision VMs on KVM with Terraform.
one of the steps in installations is to download and install the provider buy the command:
go install github.com/dmacvicar/terraform-provider-libvirt#latest
but it errors:
The go.mod file for the module providing named packages contains one or
more replace directives. It must not contain directives that would cause it to be interpreted differently than if it were the main module.
I didn't find a solution, is someone has faced it?
thank you
As JimB notice in comments:
If there are replace or exclude directives in the module, the correct
installation method is to clone the source and install it,
git clone github.com/dmacvicar/terraform-provider-libvirt
cd terraform-provider-libvirt
go install
I am very new to golang. I am trying to work with the gomod. Trying to explore the go buffalo framework. But finding a bit of difficulty in installing that.
What I have done:
I saw that go get is nomore supported for buffalo and so switched to go modules.
Created a module by go mod init github.com/webbuffalotest
Fetched go get -v github.com/gobuffalo/buffalo (on the same directory where I have go.mod file)
Fetched go get -v github.com/mattn/go-sqlite3 (on the same directory where I have go.mod file)
go install github.com/gobuffalo/buffalo
I was expecting a buffalo.exe inside %GOPATH%/bin so that I can add it to my path but didn't find one.
My question is what's wrong? Is the exe not installed or it's somewhere else because of go mod. Any help will be highly appreciated.
I am using windows 10. I am not willing to install package managers as scoop or choco to install buffalo. Thanks for your patience :)
Edited:
Also tried setting set GO111MODULE=on but of no use.
Solved:
My bad, I should have used go install github.com/gobuffalo/buffalo/buffalo instead of go install github.com/gobuffalo/buffalo
github.com/gobuffalo/buffalo is a library; the corresponding binary is (aptly-named) github.com/gobuffalo/buffalo/buffalo.
The go install command you ran should have warned you about that, but didn't because go install used to also be used to cache compiled libraries (it no longer does that in module mode).
I've filed https://golang.org/issue/46912 to add a diagnostic.
