会话未创建:此版本的ChromeDriver仅支持ChromeDriver出现Chrome 74版本错误，Chrome浏览器使用Selenium [英] session not created: This version of ChromeDriver only supports Chrome version 74 error with ChromeDriver Chrome using Selenium

问题描述

我正在尝试使用rsDriver函数运行RSelenium，但是当我运行时 rD <- rsDriver() 我收到一条消息，告诉我我需要更新版本的Chrome:

I'm trying to run RSelenium using the rsDriver function, but when I run rD <- rsDriver() I get a message telling me I need a newer version of Chrome:

Selenium message:session not created: This version of ChromeDriver only supports Chrome version 74
  (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Mac OS X 10.14.3 x86_64)

Could not open chrome browser.
Client error message:
     Summary: SessionNotCreatedException
     Detail: A new session could not be created.
     Further Details: run errorDetails method
Check server log for further details.

该错误消息似乎表明我需要Chrome版本74.0.3729.6，但是当我查看Chrome的设置时，它表明我正在运行最新的稳定版本(73.0.3683.75).进一步搜寻之后，74.0.3729.6是Chrome的预发行开发版本:我是否需要安装此版本才能将ChromeDriver与RSelenium一起使用?

The error message appears to say that I need Chrome version 74.0.3729.6, but when I look in Chrome's settings, it tells me that I'm running the latest stable version (73.0.3683.75). Upon further googling, 74.0.3729.6 is a pre-release dev version of Chrome: do I need to install this in order to use ChromeDriver with RSelenium?

我不喜欢使用Chrome的想法，但是我无法让rsDriver使用Firefox:当我指定browser = "firefox"时，rsDriver会给我同样的错误消息，说明ChromeDriver不支持我的版本Chrome.

I'm not wedded to the idea of using Chrome, but I haven't been able to get rsDriver to use Firefox: when I specify browser = "firefox", rsDriver gives me the same error message about ChromeDriver not supporting my version of Chrome.

推荐答案

我今天也遇到了同样的问题，并从Google找到了这篇文章和其他文章.我想我可能有一个更直接的解决方案来修改您的代码.先前的答案在确定版本不匹配方面是正确的.

I encountered the same issue today and found this post and others from Google. I think I may have a more direct solution as a modification of your code. The previous answer is correct in identifying the mismatch in versions.

我尝试了提议的解决方案，但没有成功.我发现我的计算机上的版本是正确的.但是，此不匹配错误不是由计算机上实际安装的版本引起的，而是RSelenium代码默认情况下寻求的是Chrome/ChromeDriver的最新"版本.有关参数，请参见?rsDriver()帮助页面.

I tried the proposed solutions to no avail. I found that the versions were correct on my computer. However, this mismatch error was not resulting from the actual versions installed on the computer, but rather the RSelenium code is seeking the "latest" version of Chrome/ChromeDriver by default argument. See ?rsDriver() help page for the arguments.

如果运行帮助文档中指定的代码binman::list_versions("chromedriver")，则可以标识与该功能兼容的版本.就我而言，我能够使用以下代码建立连接.

If you run the code binman::list_versions("chromedriver") as specified in the help documentation, then you can identify the versions of compatible with the function. In my case, I was able to use the following code to establish a connection.

driver <- rsDriver(browser=c("chrome"), chromever="73.0.3683.68", extraCapabilities = eCaps)

您应该可以使用chromever=参数指定您的Chrome版本.不过，我必须使用最接近的版本(我的Chrome版本为"73.0.3683.75").

You should be able to specify your version of Chrome with the chromever= argument. I had to use the closest version, though (my chrome version was "73.0.3683.75").

希望这会有所帮助！
