install python node with colcon

edit

Hi everybody,

I'm developing a simple python node for autoware.ai, so during development I had my catkin workspace folder and to install everything I just used catkin_make command.

Here the folder structure of the node:

node_name/
├── CMakeLists.txt
├── README.md
├── launch
│   └── node_launchfile.launch
├── nodes
│   └── node_name_node.py
├── package.xml
├── setup.py
└── src
    └── node_name
        ├── __init__.py
        ├── package_1
        ├── package_2
        ├── package_3
        └── package_n

The content of setup.py is:

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

d = generate_distutils_setup(packages=['node_name'],
                             package_dir={'': 'src'})

CMakeLists.txt contains the python stuff:

find_package(catkin REQUIRED COMPONENTS
    rospy
    std_msgs
    autoware_msgs
)
catkin_python_setup()
...
catkin_install_python(PROGRAMS
    nodes/node_name_node.py
    DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

Now I'm trying to use colcon to build/install the node using:

colcon build --cmake-clean-cache --packages-up-to node_name

But when I run the node then I get:

[ERROR] [1596211499.485229]: Error loading the module package_1:
No module named node_name.package_1

So it seems like that the packages are not installed. Anyone can give me some help?
