Instapy: Firefox on RP 3

[HermanoCrespo]

I want to migrate my script to a Raspberry PI 3, Model B.

The script works well on my iMac using Chrome. I'd like to be more power efficient and not have to have the Mac on at night.

For the Pi, I need FF sadly:

session = InstaPy(username=insta_username,
password=insta_password,
use_firefox=True,
page_delay=25,
nogui=True)

Works on the iMac.

On the Pi the same script throws an error:

Traceback (most recent call last):
File "main-script-FF.py", line 20, in job
page_delay=25)
File "/home/pi/Projects/InstaPy-main-script/instapy/instapy.py", line 134, in __init__

"The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

During handling of the above exception, another exception occurred:

Ideas?

I don't know your error but I'm using firefox-esr on my RP and on my Banana Pi R2

Check out #1345 That should get you going in the right direction.

I got chromium on Pi 3 working. Download the latest chrome driver, latest chromium (>62) from debian (not ubuntu) and install both. As long as chromedriver is in path, it works perfectly fine.

I had many issues with firefox the latest being elements overlapping and selenium aborting because of that.

FYI I've updated my ansible playbooks to use @ganeshkrishnan1 method for using chrome. You can do this manually by doing the following:

first change to root user

sudo su
echo "deb http://security.debian.org/debian-security stretch/updates main" >> /etc/apt/sources.list
apt-get update
apt-get install chromium-browser
apt-get install chromedriver
mv /usr/bin/chromedriver /path/to/InstaPy/assets/chromedriver

That's it! This works for me running headless on an RPi 3.

Marto32, your recipe worked for me too. I followed your steps exactly and have a session running on my raspberry pi 3 on the command line in headless mode as I type this.

Thank you! I can finally shut the iMac down. Mother Nature thanks you too :)
