【學習日誌】Python selenium錯誤__Python

因為有些迷茫，所以準備直接上手項目

開始學習Python web驅動測試一書，沒想到一開始就發生了錯誤

環境是最新版的Python，Selenium，Firefox，Django等

按書上的代碼敲

from selenium import webdriverbrowser = webdriver.Firefox()browser.get('http://localhost:8000')assert 'Django' in browser.title

結果無情報錯

Traceback (most recent call last):  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/common/service.py", line 74, in start    stdout=self.log_file, stderr=self.log_file)  File "/usr/lib/python3.5/subprocess.py", line 947, in __init__    restore_signals, start_new_session)  File "/usr/lib/python3.5/subprocess.py", line 1551, in _execute_child    raise child_exception_type(errno_num, err_msg)FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "functional_test.py", line 2, in <module>    browser = webdriver.Firefox()  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 140, in __init__    self.service.start()  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/common/service.py", line 81, in start    os.path.basename(self.path), self.start_error_message)selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

關鍵區段大概就是說我的什麼geckodriver各種不正確

沒有找到且未添加路徑什麼的

百度了一下發現也有很多人出現這樣的問題

瞭解了一下大概

geckodriver是Firefox的驅動
但網上的解決辦法大多是win的

stackoverflow上一個老外給出了降級的辦法解決，但降級總不是好辦法，於是繼續尋找

綜合來說解決辦法為，自行安裝geckodriver，並添加到相關路徑

於是到github （戳這裡）下載了Linux的geckodriver

然後進行相關操作

sudo tar zxvf geckodriver-v0.11.1-linux64.tar.gz #解壓sudo mv geckodriver /usr/bin/ #移動到指定路徑

cd /usr/bin/                    #進入路徑

sudo chmod +x geckodriver        #除去許可權

之後再次測試Python代碼，成功

有點小爽嘿嘿
