python スクレイピング headlessモードでchromedriverが動かない

Question

試したこと
#非headless
import time
from selenium import webdriver

driver = webdriver.Chrome('/Users/nishiharakeita/Desktop/selenium/chromedriver')
driver.get('https://www.google.com/')
time.sleep(5)
search_box = driver.find_element_by_name("q")
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5)
driver.quit()

↑問題なく作動します。

#headless

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--headless')
driver = webdriver.Chrome(options=options) # 今は chrome_options= ではなく options=

driver.get('https://www.google.com/')
print(driver.title)

search_box = driver.find_element_by_name("q")
search_box.send_keys('ChromeDriver')
search_box.submit()
print(driver.title)

driver.save_screenshot('search_results.png')
driver.quit()

●質問

↑↑上記のようなエラーが出てheadlessモードではスクレイピングが機能しません。
色々と試してはいるのですがどなたか解決方法ご存知の方はご教授願います。

Answer 1

エラーメッセージが 'chromedriver' が見つからない。というように読めるので、
以下のようにchromedriverを指定したらいけるかもしれません。

chrome_driver_path = '/Users/nishiharakeita/Desktop/selenium/chromedriver'
driver = webdriver.Chrome(executable_path=chrome_driver_path, options=options)

Answer 2

driver = webdriver.Chrome('/usr/local/bin/chromedriver', options=options)

パスを指定してやりましょう。
chromedriverを置く場所を注意してください。
