Atom 1.54无法从浏览器获取xpath（使用Firefox的Selenium Webdriver）

这是我的代码：

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait

browser = webdriver.Firefox()
browser.get('https://pbx.voxbaysolutions.com/#/page/signin')

browser.find_element_by_xpath('//input[@ng-model="user.name"]').send_keys('thj')

这是错误：

Traceback (most recent call last):
  File "voxbay_automate.py", line 8, in <module>
    browser.find_element_by_xpath('//input[@ng-model="user.name"]').send_keys('thj')
  File "C:\Users\theju\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\selenium\webd
river\remote\webdriver.py", line 394, in find_element_by_xpath
    return self.find_element(by=By.XPATH, value=xpath)
  File "C:\Users\theju\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\selenium\webd
river\remote\webdriver.py", line 976, in find_element
    return self.execute(Command.FIND_ELEMENT, {
  File "C:\Users\theju\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\selenium\webd
river\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Users\theju\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\selenium\webd
river\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //input[@ng-model="user.name"]

提取元素

<input type="text" name="name" ng-model="user.name" class="form-control ng-pristine ng-invalid ng-invalid-required ng-touched" placeholder="User email" required="" tabindex="0" aria-required="true" aria-invalid="true">

解决方案

等待网络元素加载，然后发送密钥：

WebDriverWait(browser, 30).until(EC.visibility_of_element_located((By.XPATH, '//input[@ng-model="user.name"]'))).send_keys('thj')

这些进口是必需的：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
