I agree that the error message is too short.
I hope that in a future version, the go compiler will add a long 
description to each error message.

Any time you don't understand why the versions have resolved in a
particular way, I'd recommend looking at the output of `go mod graph`,
which shows all the information used by the MVS algorithm (piping it
through grep to see only the module you're interested in works well).

I've found it invaluable on many occasions.

Lacking other constraints, or with the general "major version 1" constraint 
that covers your example, many other package managers would default to the 
latest compatible version at installation time (i.e., 1.3.49). MVS picks the 
oldest compatible version, 1.2.0.

Re: [go-nuts] Re: go mod dependency hell is real

[Antoine Mercadal]

Hey,

Then why is it called mvs? I don't understand what package system would give me 
1.3.49, if I require 1.2.0 and my dependency requires 1.1.0.

I'll read a bit more about it, but you may have decreased my level of go module 
hate by a bit, sir :)

Thanks,

Hi, 

but require 1.2.0 will not work if another dependency requires the same 
package at version 1.1.0 thanks to mvs.

So either I'm wrong and I did not understand mvs, in that case I would like 
to get enlighten, or I got that right and that comforts me in my deep hate 
of mvs.

[go-nuts] Re: go mod dependency hell is real

[Darko Luketic]

Hey Sam and Pudds,

thanks for feedback and help. v1.1.7 helped.
I must say go.mod is growing on me, but it's still hindering productivity 
or let's say a step back.

If you use Goland, which probably most mousepushers like me use, since 
everything is under ~/go/pkg/
even with modules enabled in the IDE, if you don't know the exact type, it 
won't autocomplete anymore
And for each subdirectory that is not yet "connected" to the main package 
or root level updating imports and go.mod/sum needs to be done seperately
or else you won't have code completion.
So this involves finding the package name, going to their repository then 
finding the godoc reference, clicking on it, and searching on the page for 
the correct type.
For instance I forgot
r := gin.Default()
was it gin.New() or was it gin.NewRouter() ? I forgot.
So I had to do the whole jazz wasting time.
Previous to go modules, it's in ~/go/src/ the IDE had indexed the paths and 
it's available.

Now you can say, "that's not a Go modules problem, that's the IDE". Well 
yeah but the factual reality is, it's a step backwards in productivity.
Maybe it really is an IDE issue and it doesn't happen in vim.

Another concern is this Google proxy by default. That is really something I 
find feels like betrayal.
I didn't know every go modules request goes through a Google proxy by 
default until I read more about the modules topic.
And the resolution of this problem wasn't very obvious, but I had to read 
through obscure documentation.
Read the privacy policy if you can find it, then read the rather long 
document (longer than a simple: here's the one-line that turns off this 
builtin spyware)
All leaving a sour taste.

I wonder what kind of spyware Go v2 will include by default.
Not happy.

Re: [go-nuts] Re: go mod dependency hell is real

[t hepudds]

Hello Darko,

Rather than that 'replace' you found, a better solution is probably adding 
a 'require' for a more recent release of github.com/ugorji/go.

Adding this to my go.mod worked for me in a simple test just now to resolve 
a similar error to what you reported:

  require github.com/ugorji/go v1.1.7 

Using a 'require' for a recent version is better than the 'replace' you 
found for a couple reasons, including it is more forward looking, it ages 
out more gracefully, it helps anyone importing your project (avoiding the 
problem Sam W. just commented on), etc.

Or, you likely could use a later version than v1.1.7.

The v1.1.7 release of github.com/ugorji/go was specifically targeting 
resolving the error you reported, I believe. Some more details here if 
interested:
   https://github.com/ugorji/go/issues/299

thepudds

Re: [go-nuts] Re: go mod dependency hell is real

[Sam Whited]

Note that replace directives are not transitive, so every single user of
your library will need to do this. You can put it into your go.mod file
to get your library building and get tests passing, but your users will
still have to do this work as well so you'll probably want to document
that they now have to jump through hoops to use your library.
