chromedriverが読み込めなくなった。(自分用メモ)

内容

実行すると下記エラーが発生する。

$ python seleniumtest.py
Traceback (most recent call last):
  File "/usr/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 76, in start
    stdin=PIPE)
  File "/usr/lib/python3.7/subprocess.py", line 775, in __init__
    restore_signals, start_new_session)
  File "/usr/lib/python3.7/subprocess.py", line 1522, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '': ''

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "seleniumtest.py", line 4, in <module>
    driver = webdriver.Chrome(executable_path='')
  File "/usr/lib/python3.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()
  File "/usr/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 83, in start
    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: '' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

解決策

1. PATH直打ち

driver = webdriver.Chrome(executable_path='/c/******/******/chromedriver.exe')

バックスラであることに注意。

2. chromedriverの更新

下記を参照し使っているChromeのバージョンにあったchromedriverに更新する。
