Issue testing the segway.py file

[ghost]

Hi,

i'm new to ev3 gyroboy - mindstorm and i was trying to use the code in this link:

https://github.com/laurensvalk/segway/tree/master/ev3/ev3dev/python

to test it and see how it works. but i keep getting multiple errors:

1- permission denied = changed the permission to 777 2- text file busy = ??

i also created the file makelinks.sh but still can't test the code.

Thanks

First, transfer "makelinks.sh" and "segway.py" to your EV3, and put them in the same directory. To turn them into executable scripts, run:

chmod +x makelinks.sh
chmod +x segway.py

Now you can run the program:

./segway.py

hold segway up right with its resting wheels on the ground and wait for the program to start.

i'm still getting this error:

-bash: ./segway.py: /usr/bin/env: bad interpreter: Text file busy

Can you retry it after you restart the brick?

Also, can you run only

./makelinks.sh
ls -al

and give the output?

i managed to get it to run and work properly using sudo ./segway.py probably it needed admin access to force it to work.

Thanks

It shouldn't require that, though --- perhaps because something else was also accessing the file, from your previous attempts. Perhaps after a restart it shouldn't need that.
