Bitcraze Forums

i am running into issues with command line "echo 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' >> ~/.bashrc
source ~/.bashrc"

im trying to run it but it keeps saying not a valid identifier ? im novice with this type of thing im using a macbook pro trying to run this drone thank you

Hi com683,

It seems you want to try to run the Crazyflie client directly on your Mac, not using the VM, right?

There looks to be a number of things wrong with your command-line there... Can you tell me where you got the instructions to run that command?

I think the easiest way to get the client running on your Mac is to use one of the following setups, either Homebrew or MacPorts (I prefer MacPorts). The instructions are here in the client Read Me file. Look under the heading "Mac OS X."

i relied on the same site you use but im struggling i installed macports i uninstalled python and homebrew because that was the method i was using originally but now i just have macports thank you for your help perhaps you can walk me through the steps via chat if you are on around 8 pm tonight est ?

You're welcome.

It's not clear to me that you used that Read Me I linked to... The Read Me explains installing Python 3 and you are clearly using Python 2.7 in the command line you posted.

Have confidence in yourself! The Read Me is very straightforward. If you follow the directions, you should be successful. You can post further questions here.

i got it working via your route however the Gui interface is not showing the yaw and pitch in the screen it stays on the horizon all the time here is a picture i move the drone around and it is not showing up on the computer

i have a new issue i cleared it all out and now im redoing it all from scratch but this one port failed and im stuck atm
just look at the end

Hello!

Thanks for the whole log but it's obvious the errors are here. Please read your output! You can either delete the plist files that remain from your previous MacPorts installs or you can run the commands with "-force" as these error messages suggest. Once you've taken care of that, the remaining dependencies should install just fine.

What version of the Crazyflie client are you using? There was a problem where the artificial horizon graphic would not update with some firmware versions. If you install the latest cfclient software that should be fixed.

Regards!!

in order to delete the plist where do i go or do i run a command for this ? i have 2.0 crazy flie version

im still having trouble i come across this issue i uninstalled macports completely and now i have this issue need addressed im unable to fly my drone which is cruddy lol but here is the log file and im not sure what to look for thank you for your help sir im really novice at this but flying it was fun for the short time that i had it running i was able to control it well

Why don't you just use the Bitcraze 0.6 VM instead of trying to get the client installed on your computer. Also, did you know you can simply use your Android phone or iPhone to fly the Crazyflie 2? Maybe that would be easier for you to get flying again?

I'm not sure what you're trying to do based on the log but those are MacPorts errors related to the installation of swig-python. You can open the file:

/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_swig/swig-python/main.log

Like it says at the bottom of the error log you pasted and likely see what the problem is...
