Receiving OSError: [Errno 8] Exec format error: 'chromedriver.exe' on Mac [duplicate]

I am using firefox gecko driver to make a bot, I keep getting error messages with my bot and I have found that the source of the message is the:
from selenium import webdriver
browser= webdriver.Firefox()
lines.
I have added every file mentioned in the error message to path including gecko driver, firefox, and the other smaller documents. I am at a complete loss
Here is the error message:

This error message...
OSError: [Errno 8] Exec format error
...implies that the GeckoDriver binary which was invoked was not in proper format.
Your main issue is the incompatibility of the GeckoDriver binary format with respect to the underlying Operating System.
As you are on MacOS you need to download geckodriver-v0.23.0-macos.tar.gz from mozilla/geckodriver, untar/unzip it and provide the absolute path of the GeckoDriver through the argument executable_path as follows:
from selenium import webdriver
browser= webdriver.Firefox(executable_path='/path/to/geckodriver')

This may be answer to this issue,
when it shows something like, Your Firefox profile cannot be loaded. It may be missing or inaccessible.
Actual problem is, Firefox 48.0 or greater not works with selenium 3.0.0 or greater version.
so please check your versions.
so, to make it work you need to update with recent selenium and respective geckodriver version too that fixes this issue.
then try basic commands,
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()

Selenium Geckodriver and ChromeDriver not working

Running OS 10.12.6 Selenium with Python 3.6 bindings
Despite my best efforts I can't seem to get either working with Selenium. Here's the error I get:
Geckodriver error:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
The error for both chromedriver and geckodriver are essentially the same.
I've manually set my path to where these are located. Same error. I've moved the drivers to a location already in the path. Same error. Ive removed the two versions I downloaded and installed both drivers via Homebrew. Same errors. I'm not sure what to do next.

Homebrew needed to link the drivers. Once this was done they worked perfectly.

I am able to use chromedriver now without a problem. I set chromedriver.exe in a file folder renamed chromedriver, then I make sure the filepath is in parentheses. I however have the same problem with opening geckodriver through selenium despite the fact that pathlib.Path recognizes that the geckodriver.exe file exists. See if you can get chromedriver working this way:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
browser=webdriver.Chrome(r'c:\path_to_chromedriver\chromedriver\chromedriver.exe')
As in the last line above, you should make certain that you include the file path in the form of a raw string (the raw string making sure that Python doesn't read the backslashes as escape characters). If you do ever figure out how to solve your problem with geckodriver (as I have tried adding it to the system Path through advanced settings yet it didn't work), please let me know, but that should get Selenium working with Chrome.

I have created new bash script which installs automatically geckodriver, firefox, python, selenium and tests the configuration.
#!/bin/bash
apt update && apt install -y firefox python3 python3-pip
pip install selenium
INSTALL_DIR="/usr/local/bin"
json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
input=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64"))')
urls=$(echo $input | tr " " "\n")
for addr in $urls
do
url=$addr
break
done
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$INSTALL_DIR"
echo "installed geckodriver binary in $INSTALL_DIR"
python3 -c "from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)
driver.get(\"http://google.com/\")
print (\"Headless Firefox Initialized\")
driver.quit()"

launch selenium from python on ubuntu

I have the following script
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://localhost:8000')
assert 'Django' in browser.title
I get the following error
$ python3 functional_tests.py
Traceback (most recent call last): File "functional_tests.py", line 3, in <module>

pip3 list shows selenium (2.53.6).
firefox -v shows Mozilla Firefox 47.0.

I struggled with this problem as well, and I was unhappy with having to use older versions of Firefox. Here's my solution that uses the latest version of Firefox. It however involves several steps
Step 1. Download v0.9.0 Marionette, the next generation of FirefoxDriver, from this location: https://github.com/mozilla/geckodriver/releases/download/v0.9.0/geckodriver-v0.9.0-linux64.tar.gz
Step 2. Extract the file to a desired folder, and rename it to "wires". In my case I created a folder named "add_to_system_path" under Documents. So the file is in Documents/add_to_system_path/wires (also make sure that the wires file is executable under its properties)
Step 3. Create a file named ".pam_environment" under your home folder, and then adding this line on it and save
PATH DEFAULT=${PATH}:/absolute/path/to/the/folder/where/wires/is/saved
What this does is it tells ubuntu to add the enumerated dir in .pam_environment to your system path
Step 4. Save the file, log out of your user session, and log back in. This is necessary to do so that the files in the newly added system path is recognized by ubuntu
Step 5. Use the code below to instantiate the browser instance:
`
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
capabilities = DesiredCapabilities.FIREFOX
capabilities["marionette"] = True
browser = webdriver.Firefox(capabilities=capabilities)
browser.get('http://your-target-url')`
Firefox should now be able to instantiate as usual.

The last version of Firefox is not working properly with selenium. Try with 46 or 45.
You can download here: ftp.mozilla.org/pub/firefox/releases
or sudo apt-get install firefox=45.0.2+build1-0ubuntu1
You can also do this graphically as shown here http://www.howtogeek.com/117929/how-to-downgrade-packages-on-ubuntu/

Python: Cannot run Selenium with PhantomJS webdriver

I have been working on a scrapy project and have used Selenium with Firefox webdriver. Everything works fine. But now I have to use PhantomJS with Selenium. And I am getting a weird error.
Here is the code snippet I am trying to run to test that PhantomJS works with Selenium.
from selenium import webdriver
driver = webdriver.PhantomJS()
driver.set_window_size(1120, 550)
driver.get("https://duckduckgo.com/")
driver.find_element_by_id('search_form_input_homepage').send_keys("realpython")
driver.find_element_by_id("search_button_homepage").click()
print(driver.current_url)
driver.quit()
I am getting this error when I run the above code.
Traceback (most recent call last):

However, everything works fine on the above code if I replace the PhantomJS() initialization line with driver = webdriver.Firefox(). The output https://duckduckgo.com/?q=realpython is displayed. But no luck with PhantomJS.
# Here is the version of tools I am using.
Nodejs v0.10.25
PhantomJS 1.9.8
Scrapy 1.0.5
Selenium 2.53.2
I did apt-get install for Nodejs, npm and PhantomJS while pip install for scrapy and selenium. Before this, I also tried installing PhantomJS by downloading source, extracting and copying executable to bin. Also, installed PhantomJS using npm. All methods are showing the same error.
