SAMR installation has non-zero exit status

[Sebbeluriusbelurius]

Hello.

After years of using, I am now having trouble running SAM on MAC OSX 10.13.3 (High Sierra) and R version 3.4.3. I get the following error message:

Listening on http://127.0.0.1:3388
Warning: Error in library: there is no package called ‘samr’
Stack trace (innermost first):
42: library
3: runApp
2: runUrl
1: runGitHub
Error in library(samr) : there is no package called ‘samr’
ERROR: [on_request_read] connection reset by peer

This error seems to be connected to the changes in version number of my MAC OS rather than errors in SAM. Can you please help me?

I need you need to install the samr package again.. Sorry for terribly late response.
install.packages("samr")

Hello Mike. Thank you for the reply, however late. I am sorry to bother you about this again, as the solution presented does not seem to work. Here is the text i get in reply from R when writing the install command:

install.packages("samr")

Hello. I actually found a solution. I am not sure if it is the best, but it worked. I followed the solution on this link: https://apple.stackexchange.com/questions/254380/macos-sierra-invalid-active-developer-path
Essentially, I installed Xcode, and wrote xcode-select --install in the terminal. After that I restarted the computer, and was finally allowed to install the SAMR package, so that everything worked again.

Hope this works for more than me.
