Syntax Highlighting does not appear when I sudo [Arch]

[MacaroniGurl]

I installed the Syntax Highlighting through curl, and for some reason on Arch Linux it does not appear in sudo nano.

when you run sudo,the program will run as the root user therefore it will search /root for config files instead of your user home directory.so if you need syntax highlighting while running nano as root you can either copy your .nanorc file to /root or use -f option and provide the path to nanorc file.
quoting from nano man page:

-f file, --rcfile=file
Read only this file for setting nano's options, instead of reading both the system-wide and the user's nanorc files.
