ROS1 catkin_make 失败：调用 catkin_install_python() 时不需要 DESTINATION 参数

Question

我尝试将 python 脚本添加到我的包中，请参考这两个教程。

Handling of setup.py

Installing Python scripts and modules

所以我在根test\src\test_pkg 中添加了setup.py，在路径test\src 中更改了CMakeLists.txt。 （我的包根路径是test\，我的包路径是test\src\test_pkg，我的python脚本路径是test\src\test_pkg\scripts）

这是 setup.py。

#!/usr/bin/env python
# -*- coding: utf-8 -*-


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


setup_args = generate_distutils_setup(
    packages=['test_pkg'],
    scripts=['/scripts'],
    package_dir={'': 'src'}
)

setup(**setup_args)

这是 CMakeLists.txt

cmake_minimum_required(VERSION 2.8.3)
project(test_pkg)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  sensor_msgs
  message_generation
)

catkin_python_setup()

catkin_install_python(PROGRAMS scripts/talker
                      DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION})

add_message_files(
  FILES
  Num.msg
)

add_service_files(
  FILES
  AddTwoInts.srv
)

generate_messages(
  DEPENDENCIES
  std_msgs
  sensor_msgs
)

catkin_package(
  CATKIN_DEPENDS roscpp rospy std_msgs message_runtime sensor_msgs

include_directories(
# include
  ${catkin_INCLUDE_DIRS}
)

install(PROGRAMS 
  DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

然后我在路径test 中运行catkin_make。（我已经运行test\devel\setup.bat） 并得到了这个 CMake 错误：

Base path: E:\workspace\ros\test
Source space: E:\workspace\ros\test\src
Build space: E:\workspace\ros\test\build

Answer 1

首先，虽然catkin 是一个足够通用的工具，但它通常用于机器人框架 ROS。因此，通过在 ROS 的问题社区answers.ros.org 提问，您可能会得到更多回复。

CMake Error at C:/opt/ros/melodic/x64/share/catkin/cmake/catkin_install_python.cmake:20 (message):
  catkin_install_python() called without required DESTINATION argument.

我认为您提到了正确的在线资源。我也看过他们，但他们都没有澄清这一点，但 catkin_package() 需要在 catkin_install_python 之前调用。

Answer 2

正确的顺序是：

cmake_minimum_required(VERSION 2.8.3)
project(test_pkg)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  sensor_msgs
  message_generation
)

add_message_files(
  FILES
  Num.msg
)

add_service_files(
  FILES
  AddTwoInts.srv
)

generate_messages(
  DEPENDENCIES
  std_msgs
  sensor_msgs
)

catkin_package(
  CATKIN_DEPENDS roscpp rospy std_msgs message_runtime sensor_msgs

include_directories(
# include
  ${catkin_INCLUDE_DIRS}
)

#catkin_python_setup()
catkin_install_python(PROGRAMS scripts/talker
                      DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION})
)

但是由于您删除了所有未使用的代码，因此我不确定上面是否正确。如果在原始文件中，应该在此处：

    ## Mark executable scripts (Python etc.) for installation
## in contrast to setup.py, you can choose the destination)
#catkin_package()
#catkin_python_setup()
catkin_install_python(PROGRAMS scripts/talker.py scripts/listener.py
        DESTINATION   ${CATKIN_PACKAGE_BIN_DESTINATION}
)

几乎在文件末尾。

Answer 3

我遇到了同样的错误。 我以为您将代码复制到错误的位置。 如果您将这些代码放在相对较早的位置，您可能会弄错。试着把代码放在这里。

## Mark executable scripts (Python etc.) for installation
## in contrast to setup.py, you can choose the destination)
#catkin_package()
#catkin_python_setup()
catkin_install_python(PROGRAMS scripts/talker.py scripts/listener.py
        DESTINATION   ${CATKIN_PACKAGE_BIN_DESTINATION}
)
