I try to call firefox via selenium in Python on an AWS machine.
I check the previous posts (this one and this one). However, their solutions do not directly work for me. I used the following code samples, but had the errors as mentioned below.
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
driver= webdriver.Firefox()
driver.get("http://www.somewebsite.com/")
<---some code--->
#driver.close() # Close the current window.
driver.quit() # Quit the driver and close every associated window.
display.stop()
I got the following error:
> driver= webdriver.Firefox()
Traceback (most recent call last):

selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect.
If you specified a log_file in the FirefoxBinary constructor, check it for details.
I installed xvfb and pyvirtualdisplay without error. My firefox is up-to-date.
If I run firefox alone, I also got some error as follows.
> firefox &

[2]- Exit 127
Please feel free to share your thoughts. Thanks!
