How to package the robot file (.robot) from PyInstaller

[nba2023]

Python version: Python 3.6.9
Robot Framework version: 4.1.3
PyInstaller Version: 4.10
OS: Linux 5.4.0-77-generic x86~18.04.1-Ubuntu

My purpose is to package the source code from here (https://github.com/openbmc/openbmc-test-automation).
And I create an entry point by .py (loop_test.py) to execute target test case in .robot.
Then run following packaging command:
pyinstaller -D -n openbmc_robot tools/multiple-rounds/loop_test.py --distpath dist/openbmc_robot --add-data "./docs/**:docs" --add-data "./test_files/**:test_files" --add-data "./test_lists/**:test_lists"
The executable command as follows:
./openbmc_robot -c "-i 2.1.1" -n test
And get these errors:

[ ERROR ] Error in file '/openbmc/ipmi/test_ipmi_general.robot' on line 4: Resource file '../lib/ipmi_client.robot' does not exist.
[ ERROR ] Error in file '/openbmc/ipmi/test_ipmi_general.robot' on line 5: Resource file '../lib/openbmc_ffdc.robot' does not exist.

[ ERROR ] Error in file '/openbmc/ipmi/test_ipmi_general.robot' on line 9: Test library '../lib/ipmi_utils.py' does not exist.

Is there any way to package the robot file to run or only package .py file for now?
