python - 最初在 python 中创建 chromedriver 时，http.client.BadStatusLine : '' is thrown

Question

创建新的 chromedriver 实例(在 python 中)时:webdriver.Chrome("./venv/selenium/webdriver/chromedriver")，出现错误http.client.BadStatusLine :''。我没有导航到站点或使用服务器，只是创建一个新的 chromedriver。我所在的 VirtualEnv 具有最新版本的 Selenium (3.0.1) 和 chromedriver (2.24.1)。几天前这工作正常，我没有更改任何代码。我不太确定从哪里开始解决代码。我的第一步是运行 pip install --upgrade -rrequirements.txt 以确保所有软件包都是最新的。我现在唯一的想法是，selenium 不处理默认起始页，url 为 data;,，因为没有响应。然而，由于这是默认行为，如果 selenium 无法处理它自己的默认行为，我会感到惊讶。任何帮助将不胜感激!

当代码运行时(通过 bash 终端的 python)，成功创建了一个新的 chromedriver 实例，但抛出错误 http.client.BadStatusLine: ''，并且 python 终端失去与 chromedriver 的连接。

完整代码:

import pythonscripts
# Creates a new webdriver
driver = pythonscripts.md()
# Never gets here, attempts to use driver get NameError: name 'driver' is not defined

Pythonscripts md 方法:

def md():
    return webdriver.Chrome("./venv/selenium/webdriver/chromedriver")

完整错误输出:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/brydenr/server_scripts/cad_tests/pythonscripts.py", line 65, in md

    return self._request(command_info[0], url, body=data)
  File "/Users/brydenr/server_scripts/venv/lib/python3.4/site-packages/selenium/webdriver/remote/remote_connection.py", line 439, in _request
    resp = self._conn.getresponse()
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/client.py", line 1171, in getresponse
    response.begin()
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/client.py", line 351, in begin
    version, status, reason = self._read_status()
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/client.py", line 321, in _read_status
    raise BadStatusLine(line)
http.client.BadStatusLine: ''

尝试过

try:
    webdriver.Chrome("./venv/selenium/webdriver/chromedriver")
except Exception:
    webdriver.Chrome("./venv/selenium/webdriver/chromedriver")

结果是两个与之前相同的回溯，以及两个 chromedriver 实例。看起来像这样question指向 urllib 中的错误，但情况略有不同。

Answer 1

我将 chrome 更新到最新版本后发生了这种情况。我刚刚将 chromedriver 更新到 2.25，它又可以工作了。
