WebDriverException：“ chromedriver.exe”可执行文件可能具有错误的权限

标签： python selenium selenium-webdriver selenium-chromedriver

我知道这已经有很多话题了，但是我已经遍历了所有话题，这是我第三天试图突破并且没有任何改进。情况如下：

我正在尝试使用此https://github.com/tejavoo/GooglePlayReviewScraper/blob/master/scraper.py来为我的研究创建一个Google Play评论刮板，但是继续收到以下错误：

Conda3 / Python38 / Windows10 / Spyder 4.0.1

我已经确保chromedriver在PATH中，并且已将其与spyder和python一起作为所有权限。我还确保它是与我的谷歌浏览器匹配的正确版本。

我已经下载了chromedriver，将其解压缩到我正在使用的文件夹中。

在最近更新到spyder 4之前，我也没有权限错误（Winerror 5）。

请，我想念什么？ 

chromedriver = "C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe"
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('window-size=1200x600') # optional
driver = webdriver.Chrome(executable_path = chromedriver, chrome_options = options)

错误

During handling of the above exception, another exception occurred:

    driver = webdriver.Chrome(executable_path = chromedriver, chrome_options = options)

WebDriverException: 'chromedriver.exe' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

如果我更改代码并将''放在chromedriver周围

chromedriver = ("C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe")
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('window-size=1200x600') # optional
driver = webdriver.Chrome(executable_path= 'chromedriver', chrome_options = 'options')

我明白了

runcell(0, 'C:/Users/james/Downloads/ML/New folder/PlayReviews.py')
C:\Users\james\Downloads\ML\New folder\PlayReviews.py:37: DeprecationWarning: use options instead of chrome_options
  driver = webdriver.Chrome(executable_path= 'chromedriver', chrome_options = 'options')
Traceback (most recent call last):

  File "C:\Users\james\Downloads\ML\New folder\PlayReviews.py", line 37, in <module>
    driver = webdriver.Chrome(executable_path= 'chromedriver', chrome_options = 'options')

  File "C:\Users\james\.conda\envs\spyder-4.0.0_1\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 64, in __init__
    desired_capabilities = options.to_capabilities()

AttributeError: 'str' object has no attribute 'to_capabilities'

然后打开一个webdriver.py页面

非常感谢您的帮助！

干杯:)

更新

我尝试了提到的原始字符串的想法

chromedriver = "C:/Users/james/Downloads/ML/New folder/PlayReviews.py"
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('window-size=1200x600') # optional
driver = webdriver.Chrome(executable_path = r'C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe', chrome_options='options')

似乎通过了吗？到目前为止，我一直在处理此错误：

runcell(0, 'C:/Users/james/Downloads/ML/New folder/PlayReviews.py')
C:\Users\james\Downloads\ML\New folder\PlayReviews.py:39: DeprecationWarning: use options instead of chrome_options
  driver = webdriver.Chrome(executable_path = r'C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe', chrome_options='options')
Traceback (most recent call last):

  File "C:\Users\james\Downloads\ML\New folder\PlayReviews.py", line 39, in <module>
    driver = webdriver.Chrome(executable_path = r'C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe', chrome_options='options')

  File "C:\Users\james\.conda\envs\spyder-4.0.0_1\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 64, in __init__
    desired_capabilities = options.to_capabilities()

AttributeError: 'str' object has no attribute 'to_capabilities'

但是，此错误实际上来自webdriver.py的第64行，该行由于运行前者而打开

 if chrome_options:
            warnings.warn('use options instead of chrome_options',
                          DeprecationWarning, stacklevel=2)
            options = chrome_options

        if options is None:
            # desired_capabilities stays as passed in
            if desired_capabilities is None:
                desired_capabilities = self.create_options().to_capabilities()
        else:
            if desired_capabilities is None:
                desired_capabilities = options.to_capabilities()
            else:
                desired_capabilities.update(options.to_capabilities())

这是我登录并查看此处新问题的小脚本的一部分。它在C＃中的另一个库中，但也许仍然有用，它将帮助您发现问题。无论如何，下面的代码都希望对您有所帮助。

您唯一不需要做的就是在ChromeOptions上设置BinaryLocation，然后在运行时发现驱动程序目录。

此外，有时此类错误消息完全是由他们所说的错误引起的。也许为了运行selenium驱动程序，它可能需要更多提升的Windows权限，例如，当您右键单击并说以管理员身份在程序上运行时，有时会如此。您是否尝试过以管理员身份运行要运行python脚本的终端/命令行？

ChromeOptions options = new ChromeOptions();
options.BinaryLocation = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe";

using (IWebDriver driver = new ChromeDriver(GetChromeDriverDirectory(), options))
{
    driver.NavigateToUrl("https://stackoverflow.com/questions/tagged?sort=Newest&filters=NoAnswers&tagMode=Watched");
}

// Here is the method I use to get the Chrome driver directory.
private static string GetChromeDriverDirectory() => Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

当可执行文件路径不是原始字符串时，我看到了类似的权限错误。您是否尝试过像这样格式化它？

driver = webdriver.Chrome(executable_path = r'C:\\Users\\james\\Downloads\\ML\\New folder\\chromedriver.exe', chrome_options = options)

答案 2 :(得分：0)

您需要注意一些事项：

  • 使用Selenium的客户端来传递ChromeDriver的绝对路径时，您需要使用单个正斜杠< / em>以及原始的r开关。
  • 不推荐使用参数chrome_options ，相反，您需要使用options。

  • 您的有效代码块将是：

    options = webdriver.ChromeOptions()
options.headless = True
# previously: options.set_headless(headless=True)
# long ago: options.add_argument('--headless')
options.add_argument('--window-size=1200x600')
driver = webdriver.Chrome(executable_path = r'C:\Users\james\Downloads\ML\New folder\chromedriver.exe', options='options')

我终于设法弄清楚哪里出了问题。

虽然我拥有PATH且一切正确-Chromdriver.exe文件不在我的Python / scripts文件夹中。

在此设置好之后，重新放置PATH，一切正常！ ：）
