问题
I'm trying to setup Nightwatch, and am using the latest chromedriver which says it supports chrome v52-54. BUT, when I try to run the tests, it says 'Error: Chrome version must be >=52.0.2743.' Here's everything that I'm using:
- ChromeDriver 2.24
- Selenium 2.53.1
- Nightwatch v0.9.8
- Node v6.5.0
- Java v1.7.0_111
Project Structure
|-- nightwatch.json
|-- bin/
| |-- chromedriver
| |-- selenium-server-standalone-2.53.1.jar
|-- tests/
| |-- sample.js
|-- results/
|-- screens/
|-- node_modules/
| |-- (lots of modules here)
And here is my configuration file for nightwatch:
./nightwatch.json
{
"src_folders" : ["tests"],
"output_folder" : "results",
"custom_commands_path" : "",
"custom_assertions_path" : "",
"page_objects_path" : "",
"globals_path" : "",
"selenium" : {
"start_process" : true,
"server_path" : "bin/selenium-server-standalone-2.53.1.jar",
"log_path" : "results",
"host" : "127.0.0.1",
"port" : 4444,
"cli_args" : {
"webdriver.chrome.driver" : "bin/chromedriver"
}
},
"test_settings" : {
"default" : {
"launch_url" : "http://localhost",
"selenium_port" : 4444,
"selenium_host" : "localhost",
"silent": true,
"screenshots" : {
"enabled" : true,
"path" : "screens/"
},
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true
}
},
"chrome" : {
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true
}
}
}
}
Running Tests
I run the tests like this:
nightwatch tests/
Error
And I get the following output:

Anyone know how to resolve this error?
Chrome version must be >= 52.0.2743.0
Does chromedriver use my local copy of chrome? Do I need to update my actual chrome?
回答1:

Yes, ChromeDriver is a executable that selenium webdriver uses to control chrome.
So selenium webdriver launch your installed chrome from your default location or custom location which you tell to selenium webdriver during initialising ChromeDriver.
So basically ChromeDriver executable just use to talking between chrome browser and selenium webdriver to control it that doesn't mean it launches their own chrome browser. It uses your installed chrome browser.
So yes, you need to update your actual installed chrome.
回答2:
Yes, ChromeDriver uses your local Chrome installation. In case you prefer not to upgrade your Chrome installation, you can specify a version of ChromeDriver that would work with the installed Chrome version.
You can find the compatible Chrome versions for different ChromeDriver releases at https://chromedriver.storage.googleapis.com/2.25/notes.txt (change "2.25" to a newer version if your Chrome version is newer than what is listed there).
If your test framework uses the Node.js webdriver-manager, you can simply install the required ChromeDriver version (keeping any already installed versions) using (e.g. for version 2.20):
webdriver-manager update --chrome --versions.chrome=2.20
and specify the appropriate ChromeDriver version when starting Selenium via webdriver-manager:
webdriver-manager start --versions.chrome=2.20
If webdriver-manager is unavailable, you can simply download the required ChromeDriver version and use some technique to pass the following parameter to the Selenium server startup command:
-Dwebdriver.chrome.driver=/path/to/the/desired/chromedriver_version

If you're using Ubuntu 16.04 this code works:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
x64
sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
x32
sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
Install/Update
sudo apt-get update
sudo apt-get install google-chrome-stable
