Assertion error when installing PlatformIO

jankod · November 27, 2024, 8:42pm

Hello,

I’m trying to install the PlatformIO extension on my Raspberry Pi using a Remote SSH connection from VS.Code on my Windows machine.

Near the end of the installation I’m getting this error:

Error: Error: Compatible PlatformIO Core not found.
Reason: Could not run /home/pi/.platformio/penv/bin/platformio --help.
Error: Traceback (most recent call last):
  File "/home/pi/.platformio/penv/lib/python3.9/site-packages/platformio/project/helpers.py", line 74, in get_default_projects_dir
    assert IS_WINDOWS
AssertionError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/pi/.platformio/penv/bin/platformio", line 5, in <module>
    from platformio.__main__ import main
  File "/home/pi/.platformio/penv/lib/python3.9/site-packages/platformio/__main__.py", line 21, in <module>
    from platformio import __version__, ...

Any ideas?

Thanks!

Download + execute the installer script to preinstall the PlatformIO core.

Note that on Linux systems, this does need

sudo apt install python3-venv

beforehand.

Don’t forget to uninstall udev rules, too.

Thank you Max, however the issue remains.

I ran the installer script and got a confirmation the installation was successfull.

PlatformIO Core has been successfully installed into an isolated environment `/home/pi/.platformio/penv`!

The full path to `platformio.exe` is `/home/pi/.platformio/penv/bin/platformio`

If you need an access to `platformio.exe` from other applications, please install Shell Commands
(add PlatformIO Core binary directory `/home/pi/.platformio/penv/bin` to the system environment PATH variable):

See https://docs.platformio.org/page/installation.html#install-shell-commands

But when I start VS.Code, and activate the PIO extension the installer in VS.Code is running for a few minutes, and at the end I’m getting the exact same error as before.

It seems to try to determine the default path to the projects directory there.

                      except FileNotFoundError:  # command not found
                          pass
              return os.path.join(docs_dir, "PlatformIO", "Projects")

Try in order:

mkdir -p ~/Documents/PlatformIO/Projects
sudo apt install *xdg-user-dirs*

Problem solved. Creating the ‘Projects’ folder did the trick!

Thank you for your assistance Max. Greatly appreciated.
