Installing new driver, question

[Craig Young]

I am installing the TWI.py driver and have run into an error:

pi@CLOWeatherStation:~ $ wee_extension --install weewx-twi.zip
Request to install 'weewx-twi.zip'
Extracting from zip archive weewx-twi.zip
Traceback (most recent call last):

    with open(dst, 'wb') as fdst:
PermissionError: [Errno 13] Permission denied: '/usr/share/weewx/user/twi.py'
pi@CLOWeatherStation:~ $

How do I change permissions?

I tried "gahh.sudo" and got command not found, then tried "gahh.sudo wee_extension --install etc" and also got command not found.  Maybe I am doing this wrong?

This is on a raspberry pi ..

sudo wee_extension --install weewx-twi.zip

That worked .. thank you heaps.

Please tell me you're joking there.  Please.

(if not, I'd strongly suggest you do some of the nice free self-paced Linux courses and tutorials available online.  The edx.org Linux fundamentals course used to be pretty good).

Sorry for being short. I thought the link would explain it. I do hope that was a joke.

It was not a joke.  I was following the instructions in the driver documentation about how to install it.  Most documentation always used sudo, this did not, so rather than experiment and screw up my entire installation I executed it verbatim.  So simply a matter of not seeing the forest for the trees.

I'd suggest you devote a little time to consult the FAQ (link) for this and other things new users frequently run into.   It'll help explain this one as well as other things you might run into as you get more familiar with.  Your particular issue has its own page (link) as it might be the most frequent of the frequently asked questions.

Thanks Vince, am doing that now and making much better progress.
