Unusual permission error with MAVProxy

Hi all,

I have just found the solution to my problem, however I don’t understand why I would need to do this.

When installing the dev version of MAVProxy I could not get it to open. See below:

mavproxy.py 
Traceback (most recent call last):
  File "/home/dello/.local/bin/mavproxy.py", line 4, in <module>
    __import__('pkg_resources').run_script('MAVProxy==1.6.1', 'mavproxy.py')
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2927, in <module>
    @_call_aside
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2913, in _call_aside
    f(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2940, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 635, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 943, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 829, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'MAVProxy==1.6.1' distribution was not found and is required by the application

The solution that seemed to work, was to change the permission of .local/lib to 777. Has anyone else come across this issue or was it an isolated case for me?

System ->> Virtual Box running Ubuntu 16.04 LTS
Previous permission of .local/lib ->> (0700/drwx------)

Often caused by using sudo unnecessarily.

In particular, “sudo pip install --user” is likely to cause issues such as
this.

“sudo pip uninstall --user” etc etc might help clean things up…
