I'm using click 8.1.3 to parse my command,and my cli.py is like this:
@click.option('--output_dir', default=os.curdir, help='when outdated is true,choose directory which you want to put your cache file')
@click.option('--cache_dir', default=os.curdir, help='when outdated if false,choose directory where put cache file')
def main(outdated, nodes_path, river_path, cur_sta, up_sta, cutoff, upstream, downstream, cache_dir, output_dir):
……
But when I try to read cache files from a directory such as C:\Users\UserName\Desktop\test-cache, it occured wrong:
PS C:\Users\UserName\Desktop\test_cache2> calcstream --nodes_path XXX --river_path YYY --cur_sta 0 --up_sta 10 --cache_dir C:\Users\UserName\Desktop\test-cache --outdated False

It seems that the program still uses os.curdir(C:\Users\UserName\Desktop\test_cache2) to find source_project_points.csv, and I'm sure source_project_points.csv is in C:\Users\UserName\Desktop\test-cache, so how to solve the problem?
This is my project link.
Now I know, you shouldn't set default parameter in business code, rather write in @click.option(default=).
