'chromedriver.exe' executable needs to be in PATH. Please see https://chromedriver.chromium.org/home

farnking commented 11 months ago

Describe the bug Can someone tell me how to set chromedriver.exe path location for starting selenium webdriver while executing our Test-Dragon?

Project ID Facebook, Chrome

Facebook Selenium webdriver could not find the path to chromedriver in windows.
This is not a problem for firefox geckodriver. Seems that geckodriver installation takes good care of PATH environment variables in Windows. Is there a way to set environment variable PATH from python in Windows?

Facebook login page in Chromedriver

URL

To Reproduce Just select the facebook project using Chrome. Maybe you have set the PATH environment variable correctly and would not see the bug in effect.

Expected behavior

看了一下整體的錯誤，應該是解壓縮出了問題，因為console顯示tar: Error opening archive: Unrecognized archive format，所以老師可以先看一下上一個command執行後下載了甚麼東西，再決定怎麼解壓縮

各位同學，我前幾天在電腦上要執行selenium chromedirver，結果他一直當，要自動下在又找不到。後來仔細看程式碼，發現好像是這台電腦上的chrome設定跟chomedriver預設的下載URL不合。在這種情況下會跳出一個exception，告知chromedriver與chrome不合，必須下載那個版本。

根據網路教學，我們就用下列程式碼來進行下載。

        except Exception as e:
            from webdriver_manager.chrome import ChromeDriverManager

            chromeDriverUrl = "https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/{0}.70/win64/chromedriver-win64.zip"

            chrome_driver_version = str(e).split("_")[-1]
            chromeDownloadUrl = chromeDriverUrl.format(chrome_driver_version)
            os.system(chromeDriverDownloadCmd.format(chromeDownloadUrl))
            os.system('tar -xf chromedriver-win64.zip')
            self.driver = selenium.webdriver.Chrome(
                "./chromedriver-win64/chromedriver.exe", chrome_options = chrome_options
            )

可是各位可以看出來，這段程式碼沒辦法全部自動化，因為從exception中間抓下來的version號，只有三節數字，而下載需要四節數字，後面還要加一個70。

但問題試這個數字是不固定的，我上網去看，

https://googlechromelabs.github.io/chrome-for-testing/

這第四節數字有很多選擇，即使前三節數字一樣，這第四節也可能變動。請問各位同學看，該怎麼解決？

可以直接參考google的API，他是一個json file，可以直接選擇118的版本的最後一個sub-version，應該就是老師網站上看到的相對應的版本，就不需要知道他是哪一個version number，另外她還有附上download的連結，所以應該頗方便，詳細可以參考official github
