Installing github repo hadley/devtools@master from hadley

Downloading devtools.zip from https://api.github.com/repos/hadley/devtools/zipball/master

Error in function (type, msg, asError = TRUE)  : 

  SSL: certificate verification failed (result: 5)

this was with 

packageVersion("devtools")

[1] ‘1.5.0.99’

I updated from CRAN and restarted R

install.packages("devtools")

packageVersion("devtools")

[1] ‘1.5’

but identical error

I am on R version: R version 3.1.1 (2014-07-10) (x86_64-apple-darwin10.8.0)

PS: with error

devtools::install_github("devtools")

Error: Repo name should look like username/repo

you might add "for instance 'hadley/devtools' "

You probably need to update RCurl and httr.

catch 22 :-)

devtools::install_github("hadley/httr")

Installing github repo httr/master from hadley

Downloading master.zip from https://github.com/hadley/httr/archive/master.zip

Same here
R 3.1.1 on OSX 10.10
I doubt it's because of curl 7.37.1

[Tom Young]

So here,

And it seems to be related to Mac OSX 10.10 preview, as discussed here: https://secure.phabricator.com/T5913

Thanks for the info. I'm on Yosemite too and have been having the same issue.

I just managed to use install_git as a temporary workaround. So you could try

devtools::install_git("https://github.com/hadley/devtools.git")

I believe you need git, which would come with Xcode or you can install standalone.

Best,

[Matt Shirley]

install_git works for me on Mac OS 10.10. 

[Linchang Yang]

it seems fixed in 10.10 beta 3
