At first I tried the standard "from splinter import Browser" but I got the follwoing error:
from splinter import browser
ImportError: No module named 'splinter'
now, I installed it via git, and ensured the dist-packages was created. I've tried python 2.7 and 3. Now lately, I'm using the following:
#!/usr/bin/env python2 (get errors when changing to 3 as well)
import splinter
def navigate_to(web_page, how_long):
b = splinter.Browser()
b.visit(web_page)
which gives the following
Traceback (most recent call last):

I am trying to get the output of Cell.all() function from the wifi module but it shows:
Traceback (most recent call last):
File "yea.py", line 3, in <module>
cell = Cell.all('wlp0s20u2')
File "/usr/lib/python2.7/site-packages/wifi/scan.py", line 39, in all

File "/usr/lib/python2.7/subprocess.py", line 212, in check_output

errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1024, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
I have been searching for a fix for a couple of hours now, and everything I found is related to the subprocess module. Is there a way to fix this (pass a shell=True argument) or does anybody know a module similar to wifi that i could use for a simple wifi mapping script?
P.S. If it is relevant I'm using Solus 3 linux distro.
I'm trying to perform web scraping with BS4 and then do some algebra work with the results in Sage 6.2 (in Lion 10.7.5). I assumed that /Applications/Sage-6.2.app/Contents/Resources/sage/sage -i beautifulsoup4 would work, but the result is

Next, I tried upgrading to Sage 6.6. That went smoothly, as did the installation of bs4. However, when I opened the notebook, I was unable to run code cells, because the "Shift-Enter" command only registered as "Enter" and gave me a new line instead of evaluating the code. Additionally, there was no "evaluate" button. Any recommendations to solve any of these issues would be greatly appreciated.
Unfortunately, Sage has changed how it handles optional packages like BS so that older versions may not be able to use them. You can always go to a mirror, though, like http://mirrors.mit.edu/sage/spkg/optional/ download it, and put it in your (old Sage's) optional spkg directory and try doing sage -i path/to/file.
As to the notebook issue, that should be a matter of doing a "hard cache reset" in the browser due to different jQuery versions, see e.g. here.
I'm getting errors when trying to install abpcrawler (Repository below).

Am I missing something? I have Mercurial installed and am able to clone the build tools repo.
Judging from the error message, /usr/bin/firefox couldn't be started because:
OSError: [Errno 2] No such file or directory
ABP Crawler requires Firefox to be installed, it will automate Firefox in order to collect data. If Firefox is actually installed, maybe the path is /usr/local/bin/firefox or something similar. You can run which firefox from the command line if you aren't sure.

I've already double check if the "install.bat" is on the directory and it is their.
What seems to be the problem?
Thanks!
You can try adding the path to python.exe to your windows system variables.
