Setting LC_ALL doesn't work for R-Box

[amirmasoudabdol]

I'm wondering why I get this error when trying to "Clean and Build" using R-Box. I don't have this issue on RStudio or when I ran R from the terminal and it only appears inside Sublime. I've followed this instruction but it appears to be ineffective. I'm running macOS Mojave.

During startup - Warning messages:
1: Setting LC_CTYPE failed, using "C" 
2: Setting LC_COLLATE failed, using "C" 
3: Setting LC_TIME failed, using "C" 
4: Setting LC_MESSAGES failed, using "C" 
5: Setting LC_MONETARY failed, using "C"
