Open denisbrodbeck opened 7 years ago

7 years ago I just tried this here in a clean GOPATH and it works (it complains with 404's and probably shouldn't, @btracey), but it still downloads and builds (you can see that it downloads since otherwise it wouldn't pull the dependencies in your pasted output).
Your paste does miss the bitbucket.org/zombiezen/gopdf dep, but that's because you don't have hg installed. Can you try this again after installing mercurial?

7 years ago Oh no, how embarrassing:confounded: Cleaned up GOPATH and installed mercurial and now it works.
Both dep init -v and go get -v gonum.org/v1/plot/... ran through without issues. Two hours ago dep init -v got stuck for minutes multiple times at (1) try gonum.org/v1/plot@master.
go get -v gonum.org/v1/plot/... showed 404s and exited non-zero and I somehow overlooked the failed hg dependency.
I've done some testing with a fresh Ubuntu 16.04 VM.
When mercurial is not installed, dep init hangs at this position:
$ dep init -v

@kortschak Thank you for your quick reply and sorry for any inconvenience. It would be great, if your project README would include some hint, that the user needs mercurial installed, or installation might fail (creating a PR right now).

7 years ago With any luck mercurial will not be required in the near future (#389), but in the Go ecosystem, it pays to have mercurial installed since there is a history there (Go was previously distributed via mercurial).

7 years ago Could you open an issue on the website with what the behavior should be? The page doesn't exist, so I would expect a 404

7 years ago Hmm, IMO it's just a minor issue. I've looked up the go get documentation and in the end go get handles this rather clever.
Given the output:
Parsing meta tags from https://gonum.org/v1/plot?go-get=1 (status code 404)
get "gonum.org/v1/plot": found meta tag get.metaImport{Prefix:"gonum.org/v1/plot", VCS:"git", RepoRoot:"https://github.com/gonum/plot"} at https://gonum.org/v1/plot?go-get=1
gonum.org/v1/plot (download)We can see, that go get still searches and finds the meta tag in the doc header, even when the server returns a 404.
One could get rid of the 404s, if there's an actual hugo page behind the path /v1/plot/. The ?go-get=1 part shouldn't cause issues.
I suppose, something like hugo new v1/plot.md (without actual content) might suffice.
Maybe for all top level import paths:
hugo new v1/gonum.md
hugo new v1/plot.md
hugo new v1/netlib.md
hugo new v1/hdf5.mdand for each md:
