Question

操作系统：Windows7x64

npm:3.10.10

webdriver-manager:12.0.5

量角器:5.1.1

nodejs:6.10.0

错误信息：

昨天还好，我认为这个错误是新的webdriver-manager 12.0.5引起的

Answer 1

webdriver-manager@12.0.5 没有改变文件的下载方式。唯一的新鲜事是它不会在 webdriver-manager start 上下载新的缓存。可能的问题是您可能在文件写入缓存响应时取消了作业。

您可以导航到您的 webdriver-manager/selenium/ 文件夹并删除内容，或者只删除整个 selenium/ 目录，然后重试 webdriver-manager update --ignore_ssl
