Import Error

[BrownKyle]

I'm trying to test you simulator, in vagrant. After following your instructions I am unable to run api start PrecisionLand.py it gets an error importing the files from the Common folder.

api start PrecisionLand.py
GUIDED> Exception in APIThread-4: No module named Common
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/droneapi/module/api.py", line 325, in run

This is problem with your PATH variable. I just updated the readme.md with the appropriate export statements. Try those and report back

I'm still getting the same error, would I have to make these available to /ardupilot/ArduCopter as that is where they are run from and not /home/ ?

run echo $PATH and echo $PYTHONPATH and let me know what you get

Hey,

I get this:
vagrant@vagrant-ubuntu-trusty-32:~$ echo $PATH
/usr/lib/ccache:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/vagrant/src/jsbsim/src:/home/vagrant/src/ardupilot/Tools/autotest:/home/vagrant/ardupilot/Tools/autotest:/home/vagrant/visnav:/home/vagrant/visnav/Common:/home/vagrant/visnav/PrecisionLand_lib

vagrant@vagrant-ubuntu-trusty-32:~$ echo $PYTHONPATH
:/home/vagrant/visnav/PrecisionLand_lib

When I run those commands from /home/vagrant/ and the same reply when I run
it from /ardupilot/ArduCopter/ which seems to suggest it should find the
files.

Regards
Kyle

Your PYHONPATH does not match the export statements in the README. Make them match and try again. I have also never run my code on vagrant so I am not sure how it will behave.

[BrownKyle]

Hey, I can add either VisNav/ and VisNav/common through pythonpath or VisNav/precisisonland_lib. Adding all three only returns precisionland_lib. Regards Kyle

That sounds like a linux issue. I am not sure why that is happening.

[adrianhsm]

should export PYTHONPATH=$PYHTONPATH:$HOME/visnav/PrecisionLand_lib be changed to
export PYTHONPATH=$PYTHONPATH:$HOME/visnav/PrecisionLand_lib,that is PYHTONPATH to PYTHONPATH

@adrianhsm Good eye! I will put that in my next commit. Thanks
