Question

创建新的chromedriver实例（在python中）：webdriver.Chrome("./venv/selenium/webdriver/chromedriver")时，出现错误http.client.BadStatusLine: ''。我没有导航到网站，或使用服务器，只是创建一个新的chromedriver。我在VirtualEnv中拥有最新版本的Selenium（3.0.1）和chromedriver（2.24.1）。这几天前工作正常，我没有更改任何代码。我不确定从哪里开始解决代码问题。我的第一步是运行pip install --upgrade -r requirements.txt以确保所有包都是最新的。我现在唯一的想法是selenium没有处理默认的起始页面，其中url为data;,，因为没有响应。但是，由于这是默认行为，如果selenium无法处理其自己的默认行为，我会感到惊讶。任何帮助将不胜感激！

当代码运行时（通过来自bash终端的python），成功创建了一个新的chromedriver实例，但错误http.client.BadStatusLine: ''被抛出，并且python终端失去了与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

    response = self.command_executor.execute(driver_command, params)
  File "/Users/brydenr/server_scripts/venv/lib/python3.4/site-packages/selenium/webdriver/remote/remote_connection.py", line 407, in execute
    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: ''

尝试做

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。好像question指向urllib中的错误，但情况略有不同。

Answer 1

在我将chrome更新到最新版本之后发生了这种情况。我刚刚将chromedriver更新为2.25，它再次有效。

当最初在python中创建一个chromedriver时，http.client.BadStatusLine：''被抛出
