Question :
I’d like to construct my crawler using selenium on my server.
Thus I had installed/download required dependencies- such as chromedriver, chromium-browser etc on my Ubuntu17.10 server
However, when I run following code:
driver = webdriver.Chrome()
It returns following error:
---------------------------------------------------------------------------
WebDriverException Traceback (most recent call last)
<ipython-input-14-2cdab8938403> in <module>()
----> 1 driver = webdriver.Chrome()

--> 111 % (self.path, return_code)
112 )
113
WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127
What does it mean that it’s excited..?
I can’t get what the original intention of that error code and where to start to fix it.
It looks very rare case.
Maybe relevant:
I had install ubuntu desktop 17.10 on my desktop but failed to get GUI boot. Thus I am just using terminal only, but it well works so far.
I had installed ssh and remote controlling jupyter notebook from my mac to server desktop, and those errors comes from it.
Hope this info is relevant to solve this error, otherwise will abort it.
Answer #1:
It seems chromedriver
needs some extra libraries. This solved the issue for me:
apt-get install -y libglib2.0-0=2.50.3-2
libnss3=2:3.26.2-1.1+deb9u1
libgconf-2-4=3.2.6-4+b1
libfontconfig1=2.11.0-6.7+b1
I was working on a similar setup using a docker container instead of a server/VM without X / GUI.
To figure out which dependencies are required I tried iteratively to run it from the command line like this: /opt/chromedriver/2.33/chromedriver --version
over and over again.
Then at eache time I used commands like apt-cache search <STUFF>
and apt-cache madison <STUFF>
to figure out the exact version of the deb
package needed by chromedriver
2.33 (in my case, but I guess something similar would work for any version of chromedriver
).
Answer #2:
I encountered the same error when using selenium/chromedriver on my VPS. I installed chromium-browser
and the problem was gone.
sudo apt-get install -y chromium-browser
Maybe it’s not the chromium-browser
is needed, but the packages were installed along with it. However, that was a quick fix.
Answer #3:
I had a similar issue but it turned out that my problem was incorrectly set service_log_path which was pointing to a deleted folder.
webdriver.Chrome(executable_path='/path/to/chromedriver', service_log_path='/path/to/existing/folder')
Answer #4:
While working with Selenium v3.11.0, ChromeDriver v2.36 and Chrome v64.x you have to download the latest ChromeDriver from the ChromeDriver – WebDriver for Chrome and place it within your system. Next while initializing the WebDriver and the WebBrowser you have to pass the argument executable_path
along with the absolute path of the ChromeDriver as follows :
from selenium import webdriver
driver = webdriver.Chrome(executable_path='/path/to/chromedriver')
driver.get("http://www.python.org")
Answer #5:
Solved by carefully removing existing chromedriver and updating it to a newer version:
- Delete all existing chromedriver files
- Download
wget https://chromedriver.storage.googleapis.com/2.46/chromedriver_linux64.zip
(replace 2.46 bit to the newer one if needed, see compatible versions here: http://chromedriver.chromium.org/downloads) - Unzip, convert to executable by running
chmod +x chromedriver
- Move it to
mv -f chromedriver /usr/local/bin/chromedriver
so it appears in PATH
This should solve an issue. I thought updating doesn’t work because when I first tried it, I didn’t remove the older version and I was still using it accidentally.
Answer #6:
I was receiving the same selenium trace error:
WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127
My issue was due to using a different version of chromedriver (version 78) than browser (version 79) when trying to manually run the chromedriver I would see
Segmentation fault (core dumped)
Once I updated my chromedriver to match the browser it was able to start successfully
Starting ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945@{#614}) on port 9515
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
Answer #7:
I had this same issue, and the problem was due to chromedriver version.
Please ensure You are using latest Chrome Browser along with latest chromedriver.
Answer #8:
Reverting to older versions might also be a solution…
I am using Ubuntu 18.10 and installed the latest Selenium (3.141.0) and ChromeDriver (75.0.3770.8), but also had the same permission problems, and status code 127 afterwards.
I tried installing Chromium and noticed that Ubuntu was using Version 73. So I reverted from the latest version of Chromedriver (75 at this time), back to Version 73 and that worked for me.
