如何修复硒中的NoSuchElementException？

Question

我正在寻找尽可能多的数据，关于电动车公司在压缩基地，从名称，工业，总部位置。除了每一次，我尝试遇到一个问题:首先我遇到了NoSuchElementException，所以我添加了一些WebDriverWait代码，然后我遇到了一个"NameError: name 'By‘into“，修复了这个问题；由于某种原因，我现在又得到了"NoSuchElementException”。我该怎么解决这个问题？如有任何帮助，将不胜感激！)

###Import Selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

#set driver path
PATH = "C:/Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get("https://www.crunchbase.com/search/organizations/field/organization.companies/categories/electric-vehicle")

print(driver.title)
#wait to find element
WebDriverWait(driver, 20).until(
        EC.visibility_of_element_located(
          (By.XPATH, ('/html/body/chrome/div/mat-sidenav-container/mat-sidenav-content/div/search/page-layout/div/div/form/div[2]/results/div/div/div[3]/sheet-grid/div/div/grid-body/div/grid-row[1]/grid-cell[2]/div/field-formatter/identifier-formatter/a/div/div')
        )))


companies = driver.find_elements_by_class_name('ng-star-inserted')
#iterate through companies for data
for company in companies:
    name = company.find_element_by_xpath('./html/body/chrome/div/mat-sidenav-container/mat-sidenav-content/div/search/page-layout/div/div/form/div[2]/results/div/div/div[3]/sheet-grid/div/div/grid-body/div/grid-row[1]/grid-cell[2]/div/field-formatter/identifier-formatter/a/div/div').text
    industry = company.find_element_by_xpath('./html/body/chrome/div/mat-sidenav-container/mat-sidenav-content/div/search/page-layout/div/div/form/div[2]/results/div/div/div[3]/sheet-grid/div/div/grid-body/div/grid-row[1]/grid-cell[3]/div/field-formatter/identifier-multi-formatter').text
    hq = company.find_element_by_xpath('./html/body/chrome/div/mat-sidenav-container/mat-sidenav-content/div/search/page-layout/div/div/form/div[2]/results/div/div/div[3]/sheet-grid/div/div/grid-body/div/grid-row[1]/grid-cell[4]/div/field-formatter/identifier-multi-formatter/span').text
    print(name,industry,hq)

您可以尝试使用以下代码：

driver.maximize_window()
driver.implicitly_wait(30)
driver.get("https://www.crunchbase.com/search/organizations/field/organization.companies/categories/electric-vehicle")
wait = WebDriverWait(driver, 10)
print(driver.title)

name = []
industry = []
hq = []
industry_counter = 1
hq_counter = 2
companies = driver.find_elements_by_css_selector("div.identifier-label")
for company in companies:
    name.append(company.text)
    industry.append(wait.until(EC.presence_of_element_located((By.XPATH, f"(//div[contains(text(), 'Industries')]/ancestor::grid-header/following-sibling::grid-body/descendant::grid-row/grid-cell/descendant::identifier-multi-formatter)[{industry_counter}]"))).text)
    hq.append(wait.until(EC.presence_of_element_located((By.XPATH, f"(//div[contains(text(), 'Industries')]/ancestor::grid-header/following-sibling::grid-body/descendant::grid-row/grid-cell/descendant::identifier-multi-formatter)[{hq_counter}]"))).text)
    industry_counter = industry_counter + 2
    hq_counter = hq_counter  + 2

print(name)
print(industry)
print(hq)
