Answer 1

您正在使用chromediver 2.32,并在发行说明中写道支持适用于Chrome v59-61

作为浏览器你有:

Chrome Version 62.0.3202.62 (Official Build) (64-bit) 

因此,从ChromeDriver,你应该使用2.33

Answer 2

我有类似的错误.但版本匹配:我使用的是Chrome 65,驱动程序版本为2.38.

我花了很长时间,试图理解这个问题.最后,发现它是由空/etc/hosts文件引起的.显然Chrome通过localhost,如果这样的条目丢失/etc/hosts- 它将崩溃.

所以,请确保它有这样的条目:

127.0.0.1 localhost
