how to fix it

The working directory may be incorrect. Please run npm install in the your directory of srvpro. In script it should be ~/ygopro-server, or /root/ygopro-server on your machine.
Did you forget cd ygopro-server after cloning the repo?

thanks for help, but
ln: failed to create symbolic link '.'$'\r': File exists
ln: failed to create symbolic link '.'$'\r': File exists
mkdir: cannot create directory ‘config\r’: File exists
cp: cannot create regular file 'config/config.json'$'\r': No such file or directory
which files should be removed

Not every of the 4 lns are really necessary. Depending on your OS, only 2 of them are needed. So ignore the errors from ln.
For the config, just keep the directory created, and place data/default_config.json into config/config.json. If exists, just edit it as you like.
