'chromedriver' executable needs to be in PATH.' after adding chromedriver to my PATH

I have spent hours trying to get this working to no avail. I am trying to run this test script:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://www.nytimes.com")
headlines = driver.find_elements_by_class_name("story-heading")
for headline in headlines:
print(headline.text.strip())
I have installed selenium and downloaded chromedriver as well as adding it to my PATH using sudo nano /etc/paths and adding entering the path /Users/Myname/Desktop/chromedriver. I closed out the terminal and checked it using echo $PATH and that path showed in my PATH so I'm sure it's there and /Users/Myname/Desktop/chromedriver is the location of my chromedriver exe file. However when I run the .py script above it returns "'chromedriver' executable needs to be in PATH." and I don't know what else to try.
Any help would be greatly appreciated. Thanks!

You have to add the actual path to the *.exe or chromedriver.exe in the function call, there is no need to add it to your PC's PATH variable.
NOTE: Just to clarify, for example
driver = webdriver.Chrome("/Users/Myname/Desktop/chromedriver.exe") # In Actual Add The Path To chromedriver.exe or whatever *.exe in here
Only you can know where you exe is located so just add the exe path in the function rest it will be done for you.
Happy Coding!

'chromedriver' executable needs to be in PATH in Python Django

I am trying to execute a Python script in Django. My view file is:
def generate_traffic(request):
#other code
out = run([sys.executable, 'C://Users//Maisum Abbas//learning_users//trafficapp//traffic.py', "--domain", url, "--thread", requests, "--max-clicks", maximum, "--min-clicks", minimum])
If I run the script alone without running it in Django, it works fine. Now, the problem that I am facing is that the script is not able to detect chromedriver if I run it from my function generate_traffic in view.py. I don't know what seems to be the problem since the chromedriver is in the same directory as of my other files.
myFolder
-view.py
-traffic.py (the script I am executing)
-chromedriver.exe
-otherfiles
Kindly guide me of what I am doing wrong or what seems to be the problem here.

chromedriver.exe should be added to the PATH environment variable. Apparently, you are using Windows so here are the steps to add it in Windows 10 PATH:
Search for View Advanced System Settings in the start menu and open it.
Click on the Environment Variables button.
In the newly opened window, choose Path and click on Edit.
In the new window, click on New to add a new file/dir into PATH.
For your case it should be something like this:

Place your chromedriver.exe file in your Python Directory -> Scripts Directory, it will resolve the issue. Then just write it like this in your code:
driver = webdriver.Chrome(options=options)
or
driver = webdriver.Chrome()
depending on your use.

Message: 'chromedriver.exe' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Ok, so I decided to use selenium for some code, but it doesn't work. When I put the chromedriver in my path, manually, it still doesn't work. can anyone help. PS: I already pip installed selenium.
Also, I watch/read the other article on stack overflow about this problem, but it didn't help me.

If you put chromedriver in the home directory of the user running it, that should work. Would be helpful if you stated in your question what OS/version you are using.

This problem occurs when the .py file you are running cannot find chrome driver. the best thing you can do in this situation is that the chrome driver that you installed copy and paste it in same folder as your .py file and then keep your path blank. if you keep your path blank it basically means that the .py file will search the driver on in its folder so make sure you have chrome driver in the same folder ask .py file and then keep your web driver as:
driver = webdriver.Chrome()

Well add change the code to this
import os
path = os.path.join(os.path.dirname(os.path.realpath(__file__)) + r'\chromedriver')
driver = webdriver.Chrome(executable_path = path)
So what is does is it add the chrome webdriver from path to selenium webdriver. Make sure to add the chromedriver.exe file in the root of the folder.

Can Python install files into PATH?

In order to install Selenium, step 3 on (this site indicates needing to install the chromedriver file in your PATH. I am on a work computer that does not have access to the system PATH directly. I have tried listing in the local PATH (I'm on Windows 7) variable chain like so: C:\Users\mknerr\AppData\Local\Programs\Python\Python36-32\Scripts\;C:\Users\mknerr\AppData\Local\Programs\Python\Python36-32\;C:\Users\mknerr\AppData\Local\atom\bin;C:\Users\mknerr\Programs\ChromeDriver\
(The .exe is in the ChromeDriver folder)
When I run the script with webDriver.Chrome(), I still get a WebDriverException that chromedriver needs to be in my PATH. If anyone has an idea why this isn't working from my local PATH, I'd love to hear them.
However, my real question is when I distribute this script to the rest of my team, they will likely have the same issue since my script will be calling chromedriver, which none of them will have installed, much less in their PATH. Can Python directly install a program or dependency in the PATH so they don't have to go directly accessing environment variables? I can guarantee nobody is going to feel comfortable doing that.

You can place chromedriver.exe in the same folder as the executable. Just run the program with the driver right next to it.

In our internal automation framework, we actually just distribute the Chromedriver executable as part of the framework, in the same folder as the framework's entry point.
Then, whenever we need a browser session, we do something similar to this:
import os
from selenium import webdriver
chromedriver_location = os.path.join(
os.path.dirname(os.path.abspath(__file__)), 'chromedriver.exe')
context.browser = webdriver.Chrome(executable_path=chromedriver_location)
chromedriver.exe is the default Windows name of the executable, of course; change to whatever you need.
This avoids any user setup other than installing the framework itself. No messing with PATH or any other local files.

Permission denied: 'geckodriver.log' while running selenium webdriver in python

I've installed Firefox and Selenium on centos. I'm using Xvfb and pyvirtualdisplay to open the browser.
When I try to run selenium webdriver, I'm able to open a new display but as soon as I do
browser = webdriver.Firefox()
I get the error:
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 134, in __init__
self.service = Service(executable_path, log_path=log_path)
File "/usr/lib/python2.7/site-packages/selenium/webdriver/firefox/service.py", line 45, in __init__
log_file = open(log_path, "a+")
IOError: [Errno 13] Permission denied: 'geckodriver.log'
Any clues on what's going wrong here?
EDIT : After overcoming the permission error, I'm getting
Message: 'geckodriver' executable needs to be in PATH

I had this same issue recently on a Windows 10 workstation. I fixed it by explicitly setting the service_log_path to a location I know I've got write access to:
browser = webdriver.Firefox(
service_log_path="C:\\Users\\[username]\\AppData\\Local\\Temp\\geckodriver.log"
)

Apparently this can come from an incompatibility between your firefox and your Selenium. Try pip install --upgrade selenium, and if the error is still there, try downloading a different version of Firefox, or of the gecko driver.
Regarding the message:
'geckodriver' executable needs to be in PATH
You could set the path of the driver on the script:
ff_profile_dir = "/usr/local/selenium/webdriver/firefox"
ff_profile = selenium.webdriver.FirefoxProfile(profile_directory=ff_profile_dir)
driver = selenium.webdriver.Firefox(ff_profile)
Or, according to this answer, you could run, on Unix systems, on a bash-compatible shell:
export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step
On Windows you will need to update the Path system variable to add the
full directory path to the executable geckodriver manually or command
line(don't forget to restart your system after adding executable
geckodriver into system PATH to take effect). The principle is the
same as on Unix.

I was having the same problem. I tried using Ivan Chaer's answer, but it didn't work. I tried a whole bunch of other things until I finally came across a working solution. All the time I had been trying to run Selenium, I had been using the interactive shell. When I tried putting the code in a script and then running it instead, everything worked fine.
I then noticed that a file named "geckodriver.log" had been created in the same directory as the script. That gave me an idea. I created a "geckodriver.log" file in C:\Program Files\Python36 and then using Selenium with Firefox no longer threw any errors.

The following solution worked for me. In my case I was starting my Python script from within the Windows Notepad++ application. My geckodriver.exe was in the PATH and happened to be located in my C:\Python 27 folder. A full path to Firefox was also provided. Selenium, geckodriver and Firefox were all on the latest versions.
It turn out that the geckodriver.log file was being created here:
C:\Program Files (x86)\Notepad++\geckodriver.log
I found this by running Notepad++ as an Administrator. It was then able to create the file where it wanted. I then located the file and changed the file permissions to full access for the normal user account on Windows (it was set to be read only).
After doing this, I was able to run Notepad++ normally and the error was gone.

I had the same issue while working with python IDLE.
I just ran IDLE shell as Administrator.
Now on running the commands below works fine.
from selenium import webdriver
browser = webdriver.Firefox() #opens up a new Firefox window

I had this exact same error.
[Errno 13] Permission denied: 'geckodriver.log'
The problem was not at all with this .log file.
The real problem was that my script (.py file) and the geckodriver.exe were not located in the same folder.
Once I put them in the same folder, the problem was solved and the function was executed normally.
browser = webdriver.Firefox()
Hope this helps.

I had the exact same problem. I went on the selenium's pypi page. In the Drivers section they talk about geckodriver and you can find the link to the geckodriver executable that suits your browser and OS.
I just downloaded it, unzipped it and then placed the geckodriver.exe file in C:\Program Files\Python37 (Python37 is already in my PATH). And it now works fine.

in my case, geckodriver.log was created on the script folder, but by root user, from a previous execution, them running again as a normal user python didn't have access to file and fail

I was having the same problem trying to run an interactive shell exactly where my webdriver (I'm using Firefox's geckodriver) was and nothing happened, and what I came to the conclusion of is that the directory doesn't have writing privileges when you make it, therefore I set writing privileges using chmod (on Linux) and everything worked as intended. Be sure to check on privileges first to see if you can create the geckodriver.log file in the first place.

Had the same problem with Permission denied: 'geckodriver.log'
Tried a few of the options above, to no avail.
I was launching my script as a bat file from Windows scheduler. By default this runs in windows\system32...where you don't want to put the log and is a protected path.
Fixed it by updating the bat file to move to the my source code python folder
cd "C:\Users\[username]\mypy"
python.exe simpleSelenium.py
pause
