How to install PhantomJS for use with Python Selenium on the Raspberry Pi?

I want to run a Python script using

Selenium WebDriver
as a headless browser on my Raspberry Pi running Raspbian.

I originally wrote the script in OS X where it works fine. But in trying to make it work on the Raspberry, I'm having problems.

When trying to run the script, I get this error:

raise WebDriverException("Can not connect to the Service %s" % self.path)
selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service /usr/bin/phantomjs

Brief version of the script:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

user_agent = ("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) " +
"AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.57 Safari/537.36")

dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap[""] = user_agent

serv_args = ["--ignore-ssl-errors=false", "--ssl-protocol=tlsv1",

driver = webdriver.PhantomJS(executable_path="/usr/bin/phantomjs",
desired_capabilities = dcap, serv_args = service_arguments, port=65000)

I have seen other people have problems resembling mine – with varying solutions – most seem to involve building PhantomJS yourself, or clone and install a Github branch adapted for Raspberry (which now is out-of-sync with the main PhantomJS project).


  • Does anyone know how to resolve the problem – and indeed what the problem really is about?

  • If the solution involves installing the binaries manually to
    or such, how would I do that? The binaries available on the PhantomJS webpage is for
    , so I'm assuming they won't work on an Raspberry Pi 2 B ARM Cortex A-7 processor.

  • I have also tried to build PhantomJS myself according to these instructions, but the process froze midway through. The Raspberry also doesn't meet the recommended hardware requirements for building.

Background info

  • I am using
    Python 2.7.9

  • I have created a
    and installed all the Python modules in it; e.g.
    pip install selenium
    , and attempt to run the script here

  • I have installed the latest version of PhantomJS via
    sudo apt-get install phantomjs

  • I have disabled my
    firewall while testing

Ok I will start with the solution, there is a version compiled for arm here phantomjs-linux-armv6l, on the pi run the following commands:

$ cd /tmp
$ wget
$ unzip
$ cd phantomjs-linux-armv6l-master
$ bunzip2 *.bz2 && tar xf *.tar

I added:

sudo cp phantomjs-1.9.0-linux-armv6l/bin/phantomjs  /usr/bin

So phantomjs will be on your path.

pi@raspberrypi ~ $ phantomjs --version

pi@raspberrypi ~ $ phantomjs

Now we have that done, time to test:

pi@raspberrypi ~ $ cat
from selenium import webdriver

driver = webdriver.PhantomJS()
a = driver.find_element_by_xpath('//*[@id="question-header"]/h1/a')
pi@raspberrypi ~ $ python

From the faq. Starting with PhantomJS 1.5, it is pure headless and there is no need to run X11/Xvfb anymore..

I tried using xvfb-run and exporting the display, using a shell script in init.d to start xvfb, I got a little further being able to run iceweasel from bash headless no problem but still no cigar when it came to phantomjs and selenium. I think it may just come down to an incompatibility between selenium and the version of phantomjs, regardless having 1.9.0 and real headless browsing is a lot more desirable.

I was in the middle of setting up a toolchain and was going to try to compile myself when I found the link above, for anyone interested in cross compiling, crosstools-ng makes life a lot easier.

I am running an arm6, there is also a compiled version for arm7 using 2.0.0, the dependencies are:

sudo apt-get install flex bison gperf ruby perl libsqlite3-dev libfontconfig1-dev libicu-dev libfreetype6 libssl-dev libpng-dev libjpeg-dev python libX11-dev libxext-dev

The install procedure, I have extracted the binary to dropbox:

chmod +x phantomjs
sudo cp phantomjs /usr/bin

The original github link is phantomjs-2.0.0-armv7
