I'm trying to use Selenium with Python.
 So, I wrote the following codes and save as the file named test.py in working directory /Users/ykt68/seleniumwork .

[ykt68@macbp15 seleniumwork]$ pwd /Users/ykt68/seleniumwork [ykt68@macbp15 seleniumwork]$ cat -n test.py 

 1 #! /usr/bin/env python 2 # -*- encoding: utf-8 -*- 3 4 from selenium import webdriver 5 from selenium.webdriver.common.keys import Keys 6 7 driver = webdriver.Firefox() 8 driver.get("http://www.python.org") 9 assert "Python" in driver.title 10 elem = driver.find_element_by_name("q") 11 elem.clear() 12 elem.send_keys("pycon") 13 elem.send_keys(Keys.RETURN) 14 assert "No results found." not in driver.page_source 15 driver.close() 

[ykt68@macbp15 seleniumwork]$ 

 These codes above are the same as 2.1 Simple Usage in documents of Selenium with Python.

 When I ran the python command for test.py above,

• FireFox browser started and opened a blank tab.
• And after about 30 seconds have passed, the following error messages were displayed and FireFox window was closed.

[ykt68@macbp15 seleniumwork]$ python test.py Traceback (most recent call last): File "test.py", line 7, in <module> driver = webdriver.Firefox() File "/Users/ykt68/.pyenv/versions/seleniumwork/lib/python3.5/site-packages/selenium/webdriver/firefox/webdriver.py", line 80, in __init__ self.binary, timeout) File "/Users/ykt68/.pyenv/versions/seleniumwork/lib/python3.5/site-packages/selenium/webdriver/firefox/extension_connection.py", line 52, in __init__ self.binary.launch_browser(self.profile, timeout=timeout) File "/Users/ykt68/.pyenv/versions/seleniumwork/lib/python3.5/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser self._wait_until_connectable(timeout=timeout) File "/Users/ykt68/.pyenv/versions/seleniumwork/lib/python3.5/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 108, in _wait_until_connectable % (self.profile.path)) selenium.common.exceptions.WebDriverException: Message: Can't load the profile.

 Please teach me why this error has occured and how to solve the problem or list some posts or documents I should refer.

 In addition,

1. Environments:
   • OS: Apple OS X Version 10.11.6
   • Python Version: 3.5.2
   • FireFox Version: 48.0.2
   • selenium Version: 2.53.6

[ykt68@macbp15 seleniumwork]$ python -V Python 3.5.2 [ykt68@macbp15 seleniumwork]$ /Applications/Firefox.app/Contents/MacOS/firefox -v Mozilla Firefox 48.0.2 [ykt68@macbp15 seleniumwork]$ /Applications/Firefox.app/Contents/MacOS/firefox-bin -v Mozilla Firefox 48.0.2 [ykt68@macbp15 seleniumwork]$ pip list pip (8.1.2) selenium (2.53.6) setuptools (20.10.1) [ykt68@macbp15 seleniumwork]$ 

2. I reffered the similar post of Selenium: FirefoxProfile exception Can't load the profile. So I tried

pip install -U selenium 

But the situation with error messages above remains unchanged.

Best Regards.
