使用 pythonanywhere 中的硒？

Question

我想在 pythonanywhere 中使用 selenium。这是 pythonanywhere 中的错误日志。

Traceback (most recent call last):
  File "/bin/user_wsgi_wrapper.py", line 154, in __call__
    app_iterator = self.app(environ, start_response)

    rv = self.handle_user_exception(e)

    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

所以我在 Path('/home/downtownhub/odermysite/env/bin') 中添加了 geckodrive 文件。但它发生了同样的错误。我能解决什么？？

Answer 1

啊，我看到你在使用 virtualenv。 PythonAnywhere 使用与最新版本 selenium/geckodriver 不兼容的旧版本 Firefox (v17)。切换回硒 2：

./env/bin/pip install "selenium<3"

使用 pythonanywhere 中的硒？

using selenium from pythonanywhere?

selenium

python-3.4
