I was seeing the same issue. The problem only appears when using Chrome 65 (currently: dev channel). With Chrome 64 (both stable channel and beta channel) everything worked fine.

我看到了同样的问题。该问题仅在使用 Chrome 65（当前：开发频道）时出现。使用 Chrome 64（稳定频道和测试版频道）一切正常。

It turns out I had an old chromedriver installed. Specifically, I was using chrome=65.0.3325.51with chromedriver=2.29.461585. Running npm install -g chromedriverbumped chromedriver to 2.35.528157 and now the problem is solved. Hope this helps!

原来我安装了一个旧的 chromedriver。具体来说，我使用的chrome=65.0.3325.51是chromedriver=2.29.461585. npm install -g chromedriver将 chromedriver运行到 2.35.528157，现在问题解决了。希望这可以帮助！

TL;DR: run npm install -g chromedriver

The latest chrome browser requires corresponding latest chromedriver executable for the tests to run.

最新的 chrome 浏览器需要相应的最新 chromedriver 可执行文件才能运行测试。

The error says it all :

错误说明了一切：

Your main issue is the version compatibilitybetween the binaries you are using as follows :

您的主要问题是您使用的二进制文件之间的版本兼容性如下：

• You are using chromedriver=2.33
• Release Notes of chromedriver=2.33clearly mentions the following :

• 您正在使用chromedriver=2.33
• chromedriver=2.33 的发行说明清楚地提到了以下内容：

Supports Chrome v60-62

支持Chrome v60-62

• You are using chrome=65.0
• Release Notes of ChromeDriver v2.37clearly mentions the following :

• 您正在使用chrome=65.0
• ChromeDriver v2.37 的发行说明清楚地提到了以下内容：

Supports Chrome v64-66

支持Chrome v64-66

So there is a clear mismatch between the ChromeDriverversion (v2.33) and the Chrome Browserversion (v65.0)

因此ChromeDriver版本 ( v2.33) 和Chrome 浏览器版本 ( v65.0)之间存在明显的不匹配

This issue happens when chrome and chromedriver are not in sync. Either update both to the latest version or make sure they can work together. After running the following commands it worked for me

当 chrome 和 chromedriver 不同步时会发生此问题。要么将两者都更新到最新版本，要么确保它们可以一起工作。运行以下命令后，它对我有用

npm install -g chromedriver --chromedriver-force-download
webdriver-manager update
