ImportError: No module named air_modes #59

when I try to start mode_rx I get this error:

Traceback (most recent call last): File "/usr/local/bin/modes_gui", line 30, in import air_modes ImportError: No module named air_modes

Reproduced using cc0fa1801b077c139939bc963cff17fd65ebfca1 on Debian Jessie

$ ./modes_rx                                                                                                              
Traceback (most recent call last):                                                                                                                              
  File "./modes_rx", line 27, in <module>                                                                                                                       
    import air_modes                                                                                                                                            
ImportError: No module named air_modes

That line 27 says import air_modes. It occurs both when launching ./modes_rx from the apps directory or ./apps/modes_rx from the main directory.

Please find where the installer put the Python module air_modes -- probably something like /usr/local/lib/python2.7/dist-packages/air_modes/init.py. Then add that path (in this case /usr/local/lib/python2.7/dist-packages) to env variable PYTHONPATH:

$ export PYTHONPATH=/usr/local/lib/python2.7/dist-packages

--n

I did not follow the build instructions properly... After doing it right I can now run apps/modes_rw - sorry for wasting your time !

You may be interesting in noting that, in order to have a successful install on a recently installed Debian Jessie workstation, I had to perform the following package installations:

apt-get install pyqt4-dev-tools liblog4cpp5-dev swig pip install pyZMQ

None of these (or the name of the software contained in those packages) were part of the requirements in the README file.

Thanks for your message... It helped me realize my error !

I had this issue as well. The original build output included a warning that MACOSX_RPATH was not set for the air_modes target with the result that the air_modes package wasn't being installed anywhere on my system:

CMake Warning (dev):
  Policy CMP0042 is not set: MACOSX_RPATH is enabled by default.  Run "cmake
  --help-policy CMP0042" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  MACOSX_RPATH is not specified for the following targets:

   air_modes

This warning is for project developers.  Use -Wno-dev to suppress it.

Adding the following block to CMakeLists.txt solved the problem:

if(APPLE)
    set(CMAKE_MACOSX_RPATH OFF)
endif()
