當編寫自動化腳本,定位瀏覽器元素時,報如下錯誤:
代碼:
>>> # coding=utf-8 >>> from selenium import webdriver >>> driver = webdriver.Ie() >>> driver.get("www.baidu.com") >>> driver.find_element_by_id("kw").send_keys("Selenium2")
報錯:
解決方法:
For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. (這段告訴你需要修改注冊表。)
For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. (32bit Windows看這里。)
For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.(64bit Windows看這里。)
翻譯過來的意思即,修改你的注冊表(Run->regedit->Enter),路徑如下:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE
如果FeatureControl下沒有FEATURE_BFCACHE,就以FEATURE_BFCACHE為名new一個key!並在其下創建一個DWORD,取名為:iexplore.exe,value為0。
修改完你的注冊表后,重啟你的計算機。

但是發現我再定位元素時候還是報錯,我就懷疑是不是Selenium版本問題,因為我安裝的是Selenium3.X的版本,然后我運行cmd把3.X卸載重新安裝2.X版本就好了。
卸載命令:pip uninstall selenium //卸載當前安裝的包
安裝命令:pip install selenium==2.48.0 //指定版本號安裝
查看命令:pip show selenium //查看當前包的版本信息
=============注意:如果使用的IE瀏覽器還是報錯,請參考下面網址解決=================
