couldn't install hms

[Myfanwy]

Hi,

when I ran devtools::install_github('krlmlr/hms'), I got the following readout:

Downloading GitHub repo krlmlr/hms@master from URL https://api.github.com/repos/krlmlr/hms/zipball/master Installing hms Downloading GitHub repo jimhester/covr@v2 from URL https://api.github.com/repos/jimhester/covr/zipball/v2 Error: Could not find build tools necessary to build covr

I went to his repo page, but I'm not really sure where to start to build covr. Any help would be greatly appreciated, thanks!

@jimhester: Why is devtools attempting to grab a "remote" package that is listed in the Suggests?

[krlmlr]

Thanks. Could you please try

devtools::install_github("krlmlr/hms@feature/11-covr")

If you confirm this works, I'll merge, and installation without the @ suffix will work.

@jimhester @krlmlr ok, thanks! Will try. I was also running an old version of devtools - but got the same error message after package update.

devtools::install_github("krlmlr/hms@feature/11-covr") worked!

[krlmlr]

Just out of curiosity -- does the error also occur with the bleeding-edge version of devtools?

[Myfanwy]

is the bleeding edge version devtools::install_github("hadley/devtools") ? Because if so, I just tried to run that and got the same error I did with covr:

Downloading GitHub repo hadley/devtools@master from URL https://api.github.com/repos/hadley/devtools/zipball/master Error: Could not find build tools necessary to build devtools

[Myfanwy]

must be my XCode...?

[krlmlr]

Got it sorted out: It's fixed in r-lib/devtools#1067, not merged yet. About time ;-)

I can confirm that this version of devtools doesn't attempt installing covr.

FWIW covr v2 has been merged to master and released to CRAN.
