Describe the bug
(fatal:Could not open ($NCARG_ROOT/lib/ncarg/nclscripts/cn/draw_Chinamap.ncl))
Any script containing 'draw_Chinamap.ncl' can't work as my workmates' computers do

Provide the following:
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/cn/draw_Chinamap.ncl" the bug occured here
load "$NCARG_ROOT/lib/ncarg/nclscripts/cnmap/cnmap.ncl"

Computing environment

• OS: Windows
• OS version: Ubuntu 16.04 running on Windows 10
• NCL Version: 6.6.2
• Installation method: conda

Additional context
Sometimes my system reports that 'gsn_csm.ncl' could not be opened,
I'm new to NCL, confusing about this bug. And I have asked my workmates for solving it but no one has experienced it.
