What will resolve the WebDriverError: Connection r

问题:

I cannot run Protractor tests locally, a few days ago I could but now I cannot. I even rebooted Ubuntu. Here are my versions:

$cat /etc/issue
Ubuntu 14.04.5
$node --version
v6.8.0
$npm list -g|grep protractor
└─┬ protractor@4.0.9
$webdriver-manager status
[13:49:58] I/status - selenium standalone version available: 2.53.1 [default]
[13:49:58] I/status - chromedriver version available: 2.22 [default]
[13:49:58] I/status - android-sdk is not present
[13:49:58] I/status - appium is not present
$/opt/google/chrome/chrome --version
Google Chrome 54.0.2840.59 unknown    

Here is the stack trace https://paste.fedoraproject.org/449363/35548414/

How can I fix this; are there other versions should I check?

回答1:

Something broke with the Chrome update yesterday. Get the newest chromedriver from https://sites.google.com/a/chromium.org/chromedriver/downloads and replace your current Protractor chromedriver (should be 2.22) with the newest one (2.24).

Just installing version 2.24 didn't work for me: it kept using the old version (2.21 in my case). To fix I first reinstalled a clean protractor and then updated the webdriver-manager to version 2.24:

# npm install -g protractor
# webdriver-manager update --versions.chrome 2.24

I'm on windows. Like W4pp webdriver-manager was still trying to use 2.22 even if the executable didn't exist. My workaround is to explicitly use 2.24 instead of 2.22:

> webdriver-manager update --versions.chrome 2.24  
> webdriver-manager start --versions.chrome 2.24

Do an optional: > webdriver-manager clean before the above two commands to remove 2.22
