解决 'natfrp-service' 运行时权限错误：无法创建工作目录

The error message suggests that the 'natfrp-service' command is trying to create a directory in the '/root/.config' path but does not have the necessary permissions.

To resolve this issue, you can try the following steps:

1. Check the permissions of the '/root/.config' directory by running the following command:

ls -ld /root/.config

2. If the directory does not exist or has incorrect permissions, you can create it or modify its permissions using the following commands:

sudo mkdir /root/.config
sudo chown natfrp:natfrp /root/.config
sudo chmod 700 /root/.config

3. After ensuring that the directory exists with the correct permissions, you can try running the 'natfrp-service' command again:

sudo -u natfrp ./natfrp-service --daemon

Make sure to replace 'natfrp' with the appropriate username if necessary.

By creating the directory and setting the correct ownership and permissions, the 'natfrp-service' command should be able to create the necessary working directory without any permission denied errors.
