[SOLVED] BitCraze Client not starting

[grifo7]

Hello there!

I'm a newbie in the forum and I might be posting in the wrong place. If that's the case I apologize in advance.

Today I saw there was a new release of the crazyflie firmware. So I decided to pull all the updates in the repos in the projects folder. So far so good, the BitCraze Client icon even changed. But, for my surprise, when I tried to run the BitCraze Client I get the following terminal error:

Code: Select all

I'm not running it in the BitCraze VM. When I first started with the Crazyflie 2.0, I decided to dual boot Xubuntu 14.04 with everything the VM had (based on the 2016-06 version), to have a more snappy system. But I guess it's missing something now, right?

Could anyone help me with this?

Thank you in advance,
Grifo

Hi,

You need to update the crazyflie lib. If you have installed it from source with 'pip -e' just git pull it. If you have not installed the lib manually you can run again pip install -e . in the crazyflie client repos to update the lib version.

Thank you for your reply!

Had to delete the entire folder and git clone cflib again (don't know why) but finally got it working. Marked as resolved

I tried

Code: Select all

pip install -e .

within cflib directory first and got some errors. Then tried:

Code: Select all

pip3 install -e .

because I set up python3 as default a long time ago. Still got some permission errors.
Then I tried something I know it's not much advised:

Code: Select all

sudo pip3 install -e .

but hey, it worked

Just decided to post this so newbies like me don't go through the same.

Thank you again!
