“cannot create temp dir for user data dir” error when not running as admin

问题

I'm just able to run my python selenium code when I run it as admin. If I run it normally I get following error:

C:\startup>Python C:/startup/startupWebDriverScript.py    
Traceback (most recent call last):
  File "C:/startup/startupWebDriverScript.py", line 26, in connectGuest
    driver = webdriver.Chrome(chrome_options=chromeOptions,executable_path="C:/Python36/Chrome Webdriver/chromedriver.exe")

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot create temp dir for user data dir

This is my code:

    chromeOptions = Options()
    chromeOptions.add_argument("--use-fake-ui-for-media-stream")
    chromeOptions.add_argument("--kiosk")
    chromeOptions.add_argument("--disable-notifications")
    chromeOptions.add_argument("--disable-infobars")
    driver = webdriver.Chrome(chrome_options=chromeOptions,executable_path="C:/Python36/Chrome Webdriver/chromedriver.exe")

I'm using python 3.6, Windows 10 and selenium 3.5

Based upon my experience, It is possible you have one of following situations.
1) Either your disk is getting full, thus don't have enough free disks-pace. Try emptying your recycle bin or check for excessively generated temp files and clear those.

2) Or you have installed packages using admin privileges and hence your script doesn't have proper privileges to execute.

3) TMP environment variable may need modifications.
right click on computer and then click on properties -> advanced system settings -> environment variables ->
"User variables for " and change the TEMP and TMP vars values to "c:\temp".

I got the same error and nothing described before helped me. I fixed the problem such a way:

1. Enter echo %temp% in Windows' command-line
2. It returned C:\TEMP\2 (Why???)
3. So I created this folder and after that everything started to work

回答3:

After trying a lot of different approaches I decided to downgrade the Chrome web driver and it started to work out fine.

回答4:

Ironically, the same error message can be see on when using on Windows 10 with ChromDriver 2.37 / Chrome 65. My test code was running from within Eclipse instance. To resolve, I had to start Eclipse As an Administrator and everything worked as it should.

回答5:

I got the same error and I deleted all files in C:\Users\user\AppData\Local\Temp.

After that everything worked.

回答6:

Quick solution:

Go to the path C:\Users\Administrator\AppData\Local\Temp, and create a new folder. Rename this new folder to 2

This creates the %temp% folder that was missing.
