I would like to see the capabilities of selenium which is controlled by a python script. I downloaded the geckodriver executable and put it in some directory. I use a linux and I try run the below code through a virtualenv:
from selenium import webdriver
path = '/home/devel-20/Desktop/devel/programs'
driver = webdriver.Firefox(executable_path=path)
However, I get this error message:
Traceback (most recent call last):

os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'programs' executable may have wrong permissions.
I'm confused because I'm running this with a user called "devel-20". This is the permissions of the programs directory:
drwxrwxr-x 4 devel-20 devel-20 4096 Sep 27 07:04 programs/
And this is the permissions of the geckodriver file:
-rwxrwxr-x 1 devel-20 devel-20 12184306 Sep 16 01:48 geckodriver*
I don't understand why this permissions problem persists.
Could you give me some guidance?
Thanks a lot in advance!
The path you're referring to is not right. It should denote the geckodriver binary to use for Firefox.
An alternative approach, considering your firefox installation path is this one:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
firefox_binary = FirefoxBinary('/usr/bin/firefox')
driver = webdriver.Firefox(firefox_binary=firefox_binary)
Thanks for the response. It works fine now, using this code:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
firefox_binary = FirefoxBinary('/usr/bin/firefox')
driver = webdriver.Firefox(firefox_binary=firefox_binary)
However, I added "geckodriver" to the following folder:
/home/devel-20/Desktop/virtualenvs/restaurant/bin
This folder is in $PATH in this virtualenv. If not added to a folder which the local $PATH knows about, there will be the well-known selenium/geckodriver PATH problem.

This error message...
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver'
.
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
...implies that your program was unable to locate the GeckoDriver within the mentioned directory.
As per your code trials you have used:
driver = webdriver.Firefox()
As you havn't mentioned the absolute path of the GeckoDriver explicitly, your program searches for the GeckoDriver within the paths mentioned within your underlying Operating System PATH variable and unable to locate.
Solution
As you are on Mac OS X download the latest geckodriver-v0.23.0-macos.tar.gz from mozilla/geckodriver, store it anywhere within your system.
In your program override the paths mentioned in your Operating System PATH variable through the argument executable_path as follows:
from selenium import webdriver
driver = webdriver.Firefox(executable_path='/path/to/geckodriver')
print("Firefox Browser Invoked")
driver.get('http://google.com/')
driver.quit()
The solution above will not work on every machine depending on the absolute path you choose. Also, the absolute paths that are easy to access via any program, e.g. root folder, requires admin permissions.
There's a DriverManager module to every Selenium WebDriver that exists, and you can use it to install the WebDriver on a directory inside PATH variable automatically.
It is important that you do the installing just once. Doing it again will cause errors, and I haven't found how to overcome them yet.
First, install webdriver-manager on your Python environment with
pip install webdriver-manager
or pip3 if you're using Python3.
Do this on your code and it will work fine:
from webdriver_manager.firefox import GeckoDriverManager
try:
driver = webdriver.Firefox()
except Exception:
driver = webdriver.Firefox(GeckoDriverManager().install())
Therefore it will install only once on the machine using the program.
Note: This has some issues with OperaDriver.
Tried adding the drivers to the right path. mentioned the path in the code and yet getting runtime errors with chromedriver. Cannot see what is wrong with the code. whats wrong?
Tried adding the path to the code. imported selenium and webdriver. placed the drivers in the python directory.
from selenium import webdriver
#to open the page in Chrome.firefox
driver = webdriver.Chrome("executable_path=D:\Python\Crawler\chromedriver_win32")
driver.get("http://econpy.pythonanywhere.com/ex/001.html")
given Below are the errors:
D:\Python\Crawler\venv\Scripts\python.exe D:/Python/Crawler/crawler_sel.py

Try the below this worked for me
from selenium import webdriver
#to open the page in Chrome.firefox
def set_up(self):
self.driver = webdriver.Chrome("D:/Python/Crawler/chromedriver_win32.exe")
Your syntax here is off. It should be:
driver = webdriver.Chrome(executable_path='D:/Python/Crawler/chromedriver_win32.exe')
I've taken quotation marks off executable_path, and added .exe extension to your file path.
Alternative solution -- If you do not want to use executable_path, you can try adding chromedriver_win32.exe to your Path variable:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://econpy.pythonanywhere.com/ex/001.html")
Then, in your environment variable for Path, you have something like:
D:\Python\Crawler\chromedriver_win32.exe

I don't know Pycharm - or Python well enough to troubleshoot just what went wrong. It seems top me as if this simply bit of code should execute but I get a jumble of text that says nothing to me.
Anyone else using Selenium get this error and know how to fix it?

button = driver.find_element_by_id('LoginSubmit')
button.click()
The error says it all :
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
Which implies that GeckoDriver binary is not in the Classpath
While working with Selenium v3.x you have to download the latest GeckoDriver from this url and store it in your system and mention the absolute path while initiating the webdriver and Web Browser session as follows :
from selenium import webdriver
driver = webdriver.Firefox(executable_path="C:\\path\\to\\geckodriver.exe")
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()
For what little help it might be, the critical parts of the traceback are
FileNotFoundError: [WinError 2] The system cannot find the file specified
line 3, in <module>
driver = webdriver.Firefox()
selenium.common.exceptions.WebDriverException: Message: 'geckodriver'
executable needs to be in PATH.
It seems that the Firefox webdriver isn't in the defined search path that your main program sees. There's something called geckodriver that isn't available.
Check your installation and configuration for this package. Consult with your class instructors and classmates for help. I suspect that the repair is something with your local set-up, beyond our knowledge here.

I am unsure why the file stopped working, as it had worked previously many times before. also, both python and geckodriver are definitely defined in the path, but when run via the terminal it says that geckodriver is not in the path.
I have a feeling the issue has to do with the way geckodriver (i.e. gecko variable) is defined in a weird way in the code, or something like that. I have viewed other stack overflow posts with similar problems but have not found anything that fixed my problem. I am using Python 3.6.2 if that is helpful. Any insight would be awesome. Thank you!
As a solution to this problem, I hardcoded the full path to geckodriver in the gecko variable, instead of trying to dynamically locate it. I am unsure why the dynamic approach stopped working, but hardcoding the filepath fixed any issues for me.
