I was happily installing packages for artMS when this error popped up:
- installing source package ‘lme4’ ...
** package ‘lme4’ successfully unpacked and MD5 sums checked
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
ERROR: compilation failed for package ‘lme4’
- removing ‘/Library/Frameworks/R.framework/Versions/3.5/Resources/library/lme4’
Error in i.p(...) :
(converted from warning) installation of package ‘lme4’ had non-zero exit status
Please bear with me, I know only enough to get by when it comes to R and programming language.
I'm running on macOS Mojave 10.14.3, R v.3.5.2, RStudio v.1.1.463
When updating R, I did also install clang-6.0.0 and gfortran-6.1
There was a message to create(I think) a bin location(? - I've been struggling to understand the bin thing) using this command:
I'm not sure I executed this correctly or if this has anything to do with the error I'm getting above. All other packages in the install seemed to load fine.
Thanks so much for any help!!
