按照本教程，我构建了我的包，但我无法从另一个模块导入函数

from utils import *！

编译成功后运行节点时，出现以下错误：

Importerror: cannot import name 'sys_init' from 'utils'

你能告诉我如何成功地从其他模块导入功能吗？

  • 我有以下文件夹结构：
my_package __ src/__init__.py
          |__ scripts/utils.py
          |__ nodes/my_node.py
          |__ CmakeLists.txt
          |__ package.xml
          |__ setup.py

这是我的setup.py文件：

#!/usr/bin/python3

from distutils.core import setup
from catkin_pkg.python_setup import generate_distutils_setup

# fetch values from package.xml
setup_args = generate_distutils_setup(
    packages=['yumi_motion_api'],
    package_dir={'': 'src'},
    scripts=['scripts/utils.py'],
    requires=['rospy', 'moveit_core', 'moveit_commander', 'moveit_msgs', 'moveit_ros_planning_interface', 'std_msgs',
              'geometry_msgs','sensor_msgs', 'rospy_message_converter','tf','message_generation', 'message_runtime',
               'abb_robot_driver']
)

setup(**setup_args)

这是我的CmakeLists.txt：

cmake_minimum_required(VERSION 3.0.2)
project(yumi_motion_api)

find_package(catkin REQUIRED COMPONENTS
  rospy
  tf
  std_msgs
  geometry_msgs
  sensor_msgs
  moveit_core
  moveit_ros_planning
  moveit_ros_planning_interface
  rospy_message_converter
  message_generation
)

catkin_python_setup()
catkin_package(CATKIN_DEPENDS rospy std_msgs)
catkin_package(
 CATKIN_DEPENDS rospy std_msgs tf geometry_msgs sensor_msgs moveit_core moveit_ros_planning_interface rospy_message_converter abb_robot_driver
)
include_directories(
  nodes
  src
  scripts
  ${catkin_INCLUDE_DIRS}
)
catkin_install_python(PROGRAMS
  scripts/utils.py
  nodes/yumi_motion_api_node.py
  DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

这是我的package.xml：

<?xml version="1.0"?>
<package format="2">
