tdameritrade: Cannot find chromedriver
Python 3.7.1 Windows 10
When running the authentication, I get an error that chromedriver must be in PATH. I’ve verified that I can start chromedriver from a DOS prompt and also tried adding the path in python as shown below but it didn’t work either.
Beyond the instructions you gave, webdriver was not installed so I ran pip install selenium
and downloaded the chromedriver.exe from http://chromedriver.chromium.org/downloads
` from tdameritrade import auth os.environ[“PATH”] += os.pathsep + r’C:\Program Files\ChromeDriver’; auth.authentication(‘my_td_user_id’,‘http://localhost:8080’)

Thanks for the hint. I think I’m getting a bit further now. Instead of downloaded the webdriver.exe, I installed webdriver_manager since it seemed more portable.
I’m not sure yet if the options.binary_location is needed. But at least I’m not getting the “chromedriver’ executable needs to be in PATH” error.
pip install webdriver-managerAnd then in auth/__init__.py I addedfrom webdriver_manager.chrome import ChromeDriverManagerand replaceddriver = webdriver.Chrome(ChromeDriverManager().install(), chrome_options=options)withdriver = webdriver.Chrome(ChromeDriverManager().install())Now a chrome window is created that gives me the page belowOk, I was able to get the login screen to come up, but the program did not detect where I installed chromedriver, and I had to change it to get it to work this time. I am using openSUSE linux, and the chromedriver is installed in: /usr/lib64/chromium/chromedriver
The error that came through was this: selenium.common.exceptions.WebDriverException: Message: ‘chromedriver’ executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
I don’t know how to put that directory on my PATH permanently, as it is not in the default PATH. Here is my PATH:
Here is what came up when I imported ‘which’ and tried it:
So no response came back for the 2nd one, which(‘chromedriver’). I changed “/usr/local/bin/chromedriver” to “/usr/lib64/chromium/chromedriver” on line 33 of the init.py function, and that is how I got the appropriate web page to come up.
ONE MORE THING I FIGURED OUT - This may or may not be a common mistake, but it made it work for me in order to be able to get the authorization code.
When entering the command, you have to use the form: tdameritrade.auth.authentication(“EXAMPLE”,“https://127.0.0.1”)
and do NOT do it like this: tdameritrade.auth.authentication(“EXAMPLE@AMER.OAUTHAP”,“https://127.0.0.1”)
because the extension “@AMER.OAUTHAP” is already added in by the function written that Tim wrote in python. It can be a bit confusing because when you do it manually on the tdameritrade api pages, you have to add in that extension. But here the procedure is properly written, and so that extension is not necessary.
Thanks, Tim, for your work on this.
