推荐答案

我看到了同样的问题.该问题仅在使用 Chrome 65(当前:dev 频道)时出现.使用 Chrome 64(稳定版和 Beta 版)一切正常.

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.

事实证明我安装了一个旧的 chromedriver.具体来说，我使用 chrome=65.0.3325.51 和 chromedriver=2.29.461585.运行 npm install -g chromedriver 将 chromedriver 撞到 2.35.528157，现在问题解决了.希望这会有所帮助！

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

TL;DR:运行 npm install -g chromedriver
