"No module named 'ioctl_opt'" on running tests #39

Closed wimrijnders closed 4 years ago

wimrijnders commented 4 years ago

Hi there, after installing and trying to run the tests I get:

Failure: ModuleNotFoundError (No module named 'ioctl_opt') ... ERROR

And all tests appear to fail. Any idea what's going on? (python noob)

Terminus-IMRC commented 4 years ago

I suspect you cloned the repository instead of installing directly with git. In this case, you should manually install the ioctl-opt Python package. Please run pip3 install --user 'ioctl-opt >= 1.2' in your shell.

Also, install NumPy with pip3 install --user numpy if it's missing.

Not sure what happened here. Now, every time I run pip3, I get this:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line
33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ModuleNotFoundError: No module named 'pip._vendor.cachecontrol'

During handling of the above exception, another exception occurred:

Your pip seems to be broken. Does anything change after running the commands below in your shell?

$ sudo apt update
$ sudo apt install --reinstall python3-pip
$ python3 -m pip install --user --upgrade pip
$ python3 -m pip install --user --upgrade ioctl-opt numpy

If things don't go well, then you might be needed to replace your SD card because SD cards are easily broken.

@Terminus-IMRC thanks for helping out, but no luck here.

Searching online, I found that this is a common problem with pythong 3.8. However, I have not found a satisfactory solution yet. Will try another pi.

wimrijnders commented 4 years ago

On the Pi4 it worked in one go; however, tests are failing.

I will assume that the sd-card is just bad. I'll open another issue for the failing tests.

Terminus-IMRC commented 4 years ago

Please note that py-videocore6 only works on Raspberry Pi 4, as noted in README.md. For Raspberry Pi 1/2/3/Zero, use py-videocore instead.

wimrijnders commented 4 years ago

OK, noted. I will test that as soon as I get a new SD-card configured.

But pip3 should still work.
