问'str' object has no attribute 'to_capabilities'？

from selenium import webdriver

from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome(chrome_options='C:/Users/Lenovo/AppData/Local/Google/Chrome/Application/chromedriver.exe')
driver.get("http://127.0.0.1:8089")
# driver.maximize_window()

# 等待浏览器的加载  5
driver.implicitly_wait(5)
# # 获取浏览器最后一个句柄
newhandle = driver.window_handles[-1]
# newhandle1 = driver.window_handles[0]
print(newhandle)
# 窗口最大化
driver.maximize_window()

# 找到类site-nav-right fr 删除里边的target，就是删除css样式的打开一个新窗口
driver.execute_script('document.getElementsByClassName("site-nav-right fr")[0].childNodes[3].removeAttribute("target")')
driver.find_element_by_link_text('注册').click()

driver.find_element_by_name('username').click()
ActionChains(driver).send_keys('123').send_keys(Keys.TAB).send_keys('123456').send_keys(Keys.TAB).send_keys('123456').send_keys(Keys.TAB).send_keys('15212345678').send_keys(Keys.TAB).send_keys('123@qq.com').send_keys(Keys.ENTER).perform()

print('注册成功')
