CRICKIT library problems Moderators: adafruit_support_bill, adafruit

[Subfolder770]

I recently obtained the RPi CRICKIT hat, and followed the instructions as listed here https://learn.adafruit.com/adafruit-crickit-hat-for-raspberry-pi-linux-computers/python-installation . Everything seems to run smoothly until I run my program. I use

Code: Select all | TOGGLE FULL SIZE

from adafruit_crickit import crickit

like the guide said to use, but I get

Code: Select all | TOGGLE FULL SIZE

ImportError: No module name adafruit_crickit

. Any solutions or fixes?

[adafruit_support_mike]

Are you sure you're using the Python3 interpreter?

Python-2.7 and Python-3 are only kind-of compatible, and have different file trees for loadable modules. The installer will put a module in the file tree of the interpreter that was running at the time, but the module might not bbe visible to any other version of Python.

[Subfolder770]

Yes, I am using Python 3 and as far as I can see, everything is updated properly and should be running smoothly.

[adafruit_support_mike]

'Should work' is the default state for any project. 'Does work' is significantly less common.

Post the output from the command:

Code: Select all | TOGGLE FULL SIZE

pip3 install adafruit-circuitpython-crickit


between CODE tags please. Let's see what the package system has to say for itself.

The results are in, they say...

Code: Select all | TOGGLE FULL SIZE

:~ $ pip3 install adafruit-circuitpython-crickit

Okay, it looks like that command installed a batch of new modules. Does the example code still fail when you try to run it?

[Subfolder770]

It does seem that way, but the program still returns the no such library. I checked the spelling for the library and it is the same.

[adafruit_support_mike]

Okay, what do you get from:

Code: Select all | TOGGLE FULL SIZE

ls -l /usr/bin/python*


and what's the exact command you're using to run the Python environment where the scripts throw the error message?

[Subfolder770]

The results are

And I am just using the default python editor to run the program

[adafruit_support_mike]

The default version of Python is Python-2.7.

You need to use Python-3, which is `python3` on the command line.

[Subfolder770]

I did run the program from the terminal using

Code: Select all | TOGGLE FULL SIZE

python3

and using the default python for my pi, python 3
(default meaning the only one that shows up on the start menu)

[adafruit_support_mike]

Okay, let's approach this from the other end.

What output do you get from the command:

Code: Select all | TOGGLE FULL SIZE

find /usr/local/lib/py* -name "adafruit*"


[Subfolder770]

I get nothing, it just returns me to the terminal prompt without any output

[adafruit_support_mike]

That means the libraries weren't installed where they're supposed to be.

Let's brute-force things to find out where they did go:

Code: Select all | TOGGLE FULL SIZE

sudo find / -name "adafruit*"


That may take as much as a few hours to run. It will look at every file on the SD card.
