问题
I'm trying to follow the documentation provided by Aldebaran here in order to get my NAO ready for Python programming. I correctly dowloaded the NAOqi framework adapted to my OS (linux 64 bits) then I typed the command line $ export PYTHONPATH=${PYTHONPATH}:/path/to/python-sdk which, if I understand things right, should be typed in a terminal and not in a Python shell.
Then I typed import naoqi in a Python shell and got the ImportError: No module named naoqi error, so I tried troubleshooting and typed
import sys
print "\n".join(sys.path)
in the same Python sheel and got that :
/home/*****
/usr/bin
/usr/lib/python2.7
/usr/lib/python2.7/plat-linux2
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages/PIL
/usr/lib/python2.7/dist-packages/gst-0.10
/usr/lib/python2.7/dist-packages/gtk-2.0
/usr/lib/python2.7/dist-packages/ubuntu-sso-client
/usr/lib/python2.7/dist-packages/ubuntuone-client
/usr/lib/python2.7/dist-packages/ubuntuone-control-panel
/usr/lib/python2.7/dist-packages/ubuntuone-couch
/usr/lib/python2.7/dist-packages/ubuntuone-installer
/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol
so I indeed don't have /path/to/python-sdk as I shoud but not I'm blocked. What should I do to solve that ?
I will add that I am new to Linux, Python and NAO so I'm sorry if the answer is actually obvious.
I have been trying to configurate my NAO for Python programming for almost 1 week so I really feel retarded. I need your help please.
回答1:
Suppose you have naoqi installed in /home/user/naoqi
1.- Open a text editor (Kate, Gedit,... whatever)
2.- Open the file /home/user/.profile
3.- At the end of the file, add the following line
export PYTHONPATH=${PYTHONPATH}:/home/user/naoqi
4.- Reboot (Close your session and login again also works, but just to be sure)
NOTE: Remember to change /home/user/naoqi with the correct path
回答2:
I had this issue for a while until I came across the Python SDK - Troubleshooting page which states that the path to the naoqi.py file that should be on your PYTHONPATH is /path/to/python-sdk/lib/python2.7/site-packages
I added the following line to my .bashrc file
export PYTHONPATH=${PYTHONPATH}:/path/to/naoqi/lib/python2.7/site-packages
and then ran source .bashrc in the terminal.
You can test if the path has been added correctly by running the following lines of code in a python2 terminal.
import sys
print "\n".join(sys.path)
You should see your above path in the list.
Lastly try import naoqi in a python2 terminal to confirm.
