Isaac Sim 4.5版本下提示ModuleNotFoundError No module named 'omni.isaac.core'问题

import argparse

from isaaclab.app import AppLauncher

# add argparse arguments
parser = argparse.ArgumentParser(description="This script demonstrates different dexterous hands.")
# append AppLauncher cli args
AppLauncher.add_app_launcher_args(parser)
# parse the arguments
args_cli = parser.parse_args()

# launch omniverse app
app_launcher = AppLauncher(args_cli)
simulation_app = app_launcher.app
###以上都是启动isaacsim的代码

###以下是测试具体api的代码
import sys
#print(sys.path)
import isaacsim.core.api
from isaacsim.core.api import World
print("Success! World imported.")
core_contents = dir(isaacsim.core.api)
# 打印出来查看
print("isaacsim.core.api 模块下的内容：")
for item in core_contents:
    print(item)
