Error in compileCode while installing (Mac)

[speoples]

Hi there,

I’m very new to rstan. I’m trying to download it onto my computer and it continuously comes up with an error and I’m not sure how to fix it. I’ve tried to download Rstan in Rstudio and R, with the same result. I’ve followed the instructions on the github diligently, so I’m not sure what went wrong. I downloaded xcode from the app store, as rstan requires and opened it before moving on with rstan installation.

• Here is the error I get after installing Rstan and trying out the bit of code on the github website:**

  fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’ + return ScalarReal( INTEGER(x)[0] *
  REAL(y)[0] ) ; + ’ )
  xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library

I googled parts of your error message

@speoples

xcrun: error: invalid active developer path

and found the suggestion to try running the following code in a terminal window (found /Applications/Utilities/Terminal.app):

xcode-select --install

Also, the following thread might have some more options for you if the above still doesn’t cut it:

Suggestions for OS X install wiki

The wiki currently suggests installing the command line tools by installing Xcode, a 5GB download & 9GB install size. I suggest it instead suggest simply running xcode-select --install in a terminal, which installs simply the command line tools alone. Further, I think some of the packages on which RStan depends require things like openssl, curl, etc, in which case I think we should be recommending folks use the mature/popular homebrew package management system. Indeed, a simple shell script to…

That seems to have solved the problem. Thank you very much!
