PyCharm中运行firefox webdriver访问邮箱添加通讯录的时候报错-WebDriverException: Message: can‘t access dead object
调了半天，发现是因为在登录操作后没有从frame中切换出来导致的，因为在登录的时候需要先切换到frame中，登录之后要切换出来才能继续其他操作。
下面是我运行的代码，driver.switch_to.default_content()这一行被我注释掉了，结果就报这个错
代码：
driver=webdriver.Firefox(executable_path=‘c:\\geckodriver‘)
driver.get(‘http://mail.126.com‘)
try:
wait=WebDriverWait(driver,10,0.2)#显示等待
driver.switch_to.frame(driver.find_element_by_xpath("//iframe[@id=‘x-URS-iframe‘]"))#切换到用户名和密码输入框所在的frame元素
name=wait.until(lambda x:x.find_element_by_xpath("//input[@placeholder=‘邮箱帐号或手机号‘ and @name=‘email‘]"))
name.send_keys(‘xiaxiaoxu1987‘)
password=wait.until(lambda x:x.find_element_by_xpath("//input[@placeholder=‘密码‘]"))
password.send_keys(‘gloryroad‘)
submit=wait.until(lambda x:x.find_element_by_xpath("//a[@id=‘dologin‘]"))
submit.click()
#driver.switch_to.default_content()#在pycharm里用switch_to_default_content()会被加删除线，out了
address_book_link=wait.until(lambda x:x.find_element_by_xpath("//div[text()=‘通讯录‘]"))
address_book_link.click()
运行报错：

把注释去掉：
driver=webdriver.Firefox(executable_path=‘c:\\geckodriver‘)
driver.get(‘http://mail.126.com‘)
try:
wait=WebDriverWait(driver,10,0.2)#显示等待
driver.switch_to.frame(driver.find_element_by_xpath("//iframe[@id=‘x-URS-iframe‘]"))#切换到用户名和密码输入框所在的frame元素
name=wait.until(lambda x:x.find_element_by_xpath("//input[@placeholder=‘邮箱帐号或手机号‘ and @name=‘email‘]"))
name.send_keys(‘xiaxiaoxu1987‘)
password=wait.until(lambda x:x.find_element_by_xpath("//input[@placeholder=‘密码‘]"))
password.send_keys(‘gloryroad‘)
submit=wait.until(lambda x:x.find_element_by_xpath("//a[@id=‘dologin‘]"))
submit.click()
driver.switch_to.default_content()#在pycharm里用switch_to_default_content()会被加删除线，out了
address_book_link=wait.until(lambda x:x.find_element_by_xpath("//div[text()=‘通讯录‘]"))
address_book_link.click()
结果：没有报错

python webdriver 报错WebDriverException: Message: can't access dead object的原因（pycharm中）
