I'm working on a branch instead of master on bitbucket.org, I have up to date with this branch but still has this issue. When I switch on the master branch and deleted all the vendor things tried to regenerate, it turned out with the same issue.

What version of dep are you using (dep version)?

dep version

 version     : v0.4.1
 build date  : 2018-01-27
 git hash    : 37d9ea0
 go version  : go1.9.3
 go compiler : gc
 platform    : darwin/amd64

What dep command did you run?

dep init -v

What did you expect to see?

Generate Gopkg.toml, Gopkg.lock, and vendor/

What did you see instead?

Same issue for me. This occurs on a dep init for a large project with many dependencies (tried running it after deleting the existing vendor directory).

Added some extra debugging, and for me this is the call causing the failure:

result of:

newVersionQueue(id: gps.ProjectIdentifier{ProjectRoot:"gopkg.in/fsnotify.v1", Source:""}, lockv: <nil>, prefv: <nil>, s.b: &gps.bridge{...})

is:

&gps.versionQueue{id:gps.ProjectIdentifier{ProjectRoot:"gopkg.in/fsnotify.v1", Source:""}, pi:[]gps.Version{}, lockv:gps.Version(nil), prefv:gps.Version(nil), fails:[]gps.failedVersion(nil), b:(*gps.bridge)(0xc420368120), failed:false, allLoaded:true, adverr:error(nil)}

It looks like it has something to do with the gopkg.in/fsnotify.v1 project/import.

Same issue here, also caused by gopkg.in/fsnotify.v1

The same thing:

Seems to be solved by specifying source options in Gopkg.toml:

[[constraint]]
  source = "https://github.com/fsnotify/fsnotify/archive/v1.4.7.tar.gz"
  name = "gopkg.in/fsnotify.v1"

I may be wrong (most likely), but I think the problem in different pathes to fsnotify: on the page https://gopkg.in/fsnotify.v1 there is gopkg.in/fsnotify/fsnotify.v1 path used:

go get gopkg.in/fsnotify/fsnotify.v1

I've specified source in Gopkg.toml, and got another error:
dep ensure -v

Warning: the following project(s) have [[constraint]] stanzas in Gopkg.toml:

  ✗  github.com/contiv/contivmodel
  ✗  gopkg.in/fsnotify.v1

However, these projects are not direct dependencies of the current project:
they are not imported in any .go files, nor are they in the 'required' list in
Gopkg.toml. Dep only applies [[constraint]] rules to direct dependencies, so
these rules will have no effect.

Either import/require packages from these projects so that they become direct
dependencies, or convert each [[constraint]] to an [[override]] to enforce rules
on these projects, if they happen to be transitive dependencies,

Thanks for the tip -- specifying the source for fsnotify did indeed fix the issue. Here's the constraint I used for the repo, which updates the source for the repo itself rather than tying it to a specific version:

[[constraint]]
  name = "gopkg.in/fsnotify.v1"
  source = "https://github.com/fsnotify/fsnotify.git"

@Pcyeol as specified in the warning message at the top of your run, the constraint is not used because you don't have fsnotify as a direct dependency.

You either need to add required = ["gopkg.in/fsnotify.v1"] to manually specify that the dependency is required or use an [[override]] instead of [[constraint]] to specify that this should be used for transitive dependencies as well.

@nmiyake It finally works! Sorry for this mistake.

Thanks!

I received the exact same error as everyone else though the problem for me stemmed from the fact that a dependency was only in $GOPATH and not pushed to a repository. Once I pushed my project onto GitHub dep was able to pull it and continued on without the panic.

Output before I pushed the new dependency.

This finally worked if someone is still having issues:

Had to change to override, constraint was still unhappy.

I saw the same panic: version queue is empty, should not happen error for the fsnotify.v1 package when I ran dep ensure and per @nmiyake's comment #1799 (comment) above, adding the following in Gopkg.toml resolved the error for me and then dep ensure worked fine:

  name = "gopkg.in/fsnotify.v1"
  source = "https://github.com/fsnotify/fsnotify.git"

Major update of Go dependencies, preparing for Elastic update
f2a49bc 
* Change in Elastic mapping caching was necessary as Elastic 7.*
is dropping support for type specificiation and _doc is used implicitly
and by default. Implementation was altered in a way that both 6.* and
7.* will still be supported. This is also handling the deprecation
warning which was present since 6.8 and 7.*.

See https://www.elastic.co/guide/en/elasticsearch/reference/master/removal-of-types.html

* Updateable Go packages were updated. This doesn't affect Goa which
remained on the version 1.2.1 and will require more time to update
to the latest version.

  * Update caused extra "AllowNativePasswords" parameter to be configured
  within MySQL configuration in both Segments and Tracker.

  * Update also caused an extra override of "gopkg.in/fsnotify.v1"
  in Gopkg.toml which fixed panic within "dep ensure" command.
  See golang/dep#1799 (comment).

* Index creation in Elastic docker image now creates all indices
(some of them were omitted before)

Dep was officially deprecated earlier this year, and the proposal to archive this repository was accepted. As such, I'm closing outstanding issues before archiving the repository. For any further comments, please use the proposal thread on the Go issue tracker. Thanks!
