selenium-webdriver - 未知错误：DevTools 返回未知类型：webvie

Question

无法在 Chrome 中切换到新窗口。我收到以下错误：

未知错误：DevTools 返回未知类型：webview

Answer 1

我在 Chrome 自动更新后发生了这种情况（我知道，我们真的应该禁用它）。如果您查看ChromeDriver 的发行说明，您可以验证您的 Chrome 和 ChromeDriver 版本是否兼容。

通过将 ChromeDriver 更新到最新版本，此错误已得到解决。

Answer 2

这是由于旧的 ChromeDriver，请在此处检查 ChromeDriver 并将其更新为最新版本。

Answer 3

My answer is exactly the same as the others: your chromedriver needs updating.

However: If you are using ruby (selenium, watir, etc) then you are accessing chromedriver through a helper gem called chromedriver2-helper. This gem, as well as providing chromedriver in your path, also comes with a handy chromedriver updater - also in your path - called chromedriver-update. So from the command line, I would suggest you do the following:

# Make sure your chromedriver helper is up-to-date:
gem update chromedriver
# Now update chromedriver itself.
chromedriver-update

Once that's done, hopefully your selenium should just work.
