I am using an open source project called "yaegi" in a large project.

I need to use older version of "yaegi": v.0.8.11, so I modified the go.mod file and replaced:
github.com/traefik/yaegi v0.9.2 // indirect with github.com/containous/yaegi v0.8.11
But when I build the project, it starts to update all the modules and replace it back to the most updated version:

root@ubuntu:~/myproj1# go build main.go
go: finding module for package github.com/traefik/yaegi/stdlib/unsafe
go: finding module for package github.com/traefik/yaegi/stdlib
go: finding module for package github.com/traefik/yaegi/interp
go: found github.com/traefik/yaegi/interp in github.com/traefik/yaegi v0.9.2

How can I prevent it and keep it using the old version v.0.8.11?
I read that according to https://tip.golang.org/cmd/go/#hdr-Maintaining_module_requirements:

The go command itself automatically updates the go.mod file to maintain a standard formatting and the accuracy of require statements.

Any go command that finds an unfamiliar import will look up the module containing that import and add the latest version of that module to go.mod automatically. […]

Any go command can determine that a module requirement is missing and must be added […].

Maybe there is a way to bypass it?

//indirect in go.mod means that at least one of your other modules you’re importing is dependent on that version of module, therefore go build shall automatically update that module, no matter how you changed that line in your go.mod. In your case if you don’t want to use yaegi module of v0.9.2 you have to first get rid of other dependencies dependent on that module from your project, and then fix your go.mod to make your project require yaegi v0.8.11. You can just delete them or make them require earlier version of yaegi by using their older version or editing their source code. Also, instead of editing go.mod directly, I’d run something like go get -v github.com/containous/yaegi@0.8.11 to checkout to a specific version of a module.
