jupyter - Juypter notebook can't find R kernel on El Capitan public beta -

i installed el capitan beta on spare computer test purposes try identify potential issues before others in our data science team upgrade day day machines once final release out sometime fall (note: can navigate around unix far mac programmer). kernels python 2 , 3 work fine, when try load r kernel following messages:

from within jupyter notebook get:

my first thought try reinstall r kernel (and dependencies), dependencies must compiled binaries , require xcode (for there not public beta). know of potential work around (or have ideas start looking)? i'm trying figure out if can fix on our own or if need wait on official fix jupyter group. in advance.

was able working. updating beta messed r $path homebrew , dependencies. taking following steps has fixed of issues experiencing.

1) reinstall revolution r open (or preferred r install. rro because includes intel mkl - math kernel library)

2) fix homebrew permissions:

$ sudo chown -r "$user":admin /usr/local 

3) cleanup homebrew install:

$ rm -rf /usr/local/cellar /usr/local/.git && brew cleanup 

4) reinstall homebew:

$ ruby -e "$(curl -fssl https://raw.githubusercontent.com/homebrew/install/master/install)" 

5) install os x command line tools (if not installed):

$ xcode-select --install 

6) install zqm:

$ brew install zmq 

7) launch r in terminal

$r 

8) run following:

install.packages(c('rzmq','repr','irkernel','irdisplay'),                  repos = c('http://irkernel.github.io/', getoption('repos')),                  type = 'source') irkernel::installspec() 

opening new terminal window , launching jupyter should work.
