Build suddenly fails because cannot find igraph

[gluc]

Thanks a lot for the package!

As of a few days ago, my build for gluc/data.tree suddenly stops working, saying igraph isn't available, though igraph is available.

My project is rather standard, I would say.

See here for the appveyor file: https://github.com/gluc/data.tree/blob/dev/appveyor.yml

igraph is actually not available on r-devel, see e.g. https://cran.rstudio.com/web/packages/igraph/

[gluc]

Fair enough.
The only thing I don't get is why it used to work: https://ci.appveyor.com/project/gluc/data-tree/build/1.0.9

[gaborcsardi]

Because r-devel used to have binary igraph, I guess.

I think you can just use r-release instead of r-devel, right @krlmlr ? Or is that not part of the image any more?

[krlmlr]

It's still part of the image: https://github.com/krlmlr/r-portable/tree/master/Image. But you need to override PATH, as currently it's hard-coded to r-devel:

r-appveyor/scripts/appveyor-tool.ps1

Line 75 in e2c7914

$env:PATH = $RDrive + '\R\bin\i386;' + 'C:\MinGW\msys\1.0\bin;' + $env:PATH

. This is not ideal, a better way would be to use separate images, but don't hold your breath (krlmlr-archive/r-portable#4).

Do your builds work now?

I have igraph as a Suggests package and had the same problem. Adding:

environment:
  R_VERSION: stable

to here https://github.com/dougmet/unsumnet/blob/master/appveyor.yml#L16 fixed it for me (see also #53 about release vs stable).

Thanks a lot, that did the trick!
