Question

我正在尝试硒的Simple Usage。其代码authentificateUser(email, password) : Observable<HttpResponse<any>> { return this.http.get<any>('/api/LogIn/Authentification?email=' + email + '&password=' + password, { observe: 'response' }); }给出了错误。

这是我的完整代码：

driver = webdriver.Firefox()

和结果：

while True:
    try:
        from selenium import webdriver
        from selenium.webdriver.common.keys import Keys
    except:
        print('Failed to import selenium tools, retrying...')
        continue
    else:
        print('Selenium import success!')
        break

while True:
    try:
        browser = webdriver.Firefox()
    except:
        print('Open browser error: An error occured, retrying..')
        continue
    else:
        print('Success!')
        break

browser.get('http://www.python.org')
assert "Python" in browser.title

elem = browser.find_element_by_name('q')
elem.send_keys('pycon')
elem.send_keys(Keys.RETURN)

assert "No results found" not in browser.page_source

Selenium import success! Open browser error: An error occured, retrying..Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start stdin=PIPE) File "C:\Users\user\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py", line 709, in __init__ restore_signals, start_new_session) File "C:\Users\user\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py", line 997, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified During handling of the above exception, another exception occurred: Traceback (most recent call last): File "D:\code\python project\auto.py", line 14, in <module> browser = webdriver.Firefox() File "C:\Users\user\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 160, in __init__ self.service.start() File "C:\Users\user\AppData\Local\Programs\Python\Python36-32\lib\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: 'geckodriver' executable needs to be in PATH. During handling of the above exception, another exception occurred: Traceback (most recent call last): File "D:\code\python project\auto.py", line 16, in <module> print('Open browser error: An error occured, retrying..')结果表明导入过程中没有问题。另一方面，Selenium import success!是导致问题的原因。

如何更改它才能使其正常工作？注意：我正在处理的文件名为auto.py

Answer 1

从here下载Windows版本的Geckodriver，并将其放在方便的地方。然后，在初始化geckodriver.exe变量时，将完整路径传递给browser = webdriver.Firefox(executable_path='enter_path_here')，如下所示：

Events==41

Answer 2

错误消息清楚地指出了问题："'geckodriver' executable needs to be in PATH".

您必须下载geckodriver可执行文件，并确保它位于您的PATH中。

Answer 3

像这样放置壁虎：

while True:
    try:
        browser = webdriver.Firefox(executable_path = r'D:/Automation/geckodriver.exe')
    except:
        print('Open browser error: An error occured, retrying..')
        continue
    else:
        print('Success!')
        break

请注意，D:/Automation/geckodriver.exe应该是geckodriver路径。为了您的简单起见，我已经写了这个。
