没有，除了更新ChromeDriver二进制版本之外，没有其他选择，而Chrome浏览器会不断自动更新。在

原因

每个Chrome浏览器都是在对现有功能进行某些添加、修改和删除后发布的。为了符合当前浏览器的一系列功能，Chrome团队将适时发布兼容的ChromeDriver二进制文件。这些ChromeDriver二进制文件能够与Chrome浏览器进行交互。ChromeDriver二进制文件的某些版本支持特定范围的Chrome Browser版本（一些最新版本），如下所示：

结论

要使脚本/程序与更新的Chrome浏览器保持交互，必须根据兼容性使ChromeDriver二进制版本与Chrome浏览器保持同步。在

这就是我构建的（也使用了另一个stackoverflow线程的一些预写代码），它可以为您工作。我每次都将脚本设置为从全局驱动程序脚本运行，以确保它使用正确的ChromeDriver.exe文件。在

但是在遇到此问题之前，您需要首先确保您正在安装新的驱动程序，这些脚本将自动下载最新版本/查找ChromeDriver的最新版本并将其下载到新的文件夹位置。只有当你的Chrome版本更新后，它才会使用新的文件夹位置。如果浏览器版本的chrome更新，并且在上没有可用版本，脚本应该会正常失败chromedriver.storage.谷歌皮斯.com。在

我在我的操作系统路径中设置了四个脚本，以便可以全局访问我的驱动程序。下面是我用来更新浏览器的脚本。在

希望这有道理。在
