无法通过Selenium在python中运行PhantomJS[英] Can't run PhantomJS in python via Selenium

问题描述

过去 3 天我一直在尝试通过 selenium 运行 PhantomJS,但没有成功.到目前为止,我已经尝试通过 npm 安装 PhantomJS,从源代码构建它,通过 apt-get 安装并下载预构建的可执行文件并将其放在/usr/bin/phantomjs 中.

每次我能够运行这个示例脚本 loadspeed.js :

var page = require('webpage').create(),
    system = require('system'),
    t, address;

if (system.args.length === 1) {
    console.log('Usage: loadspeed.js <some URL>');
    phantom.exit();
}

t = Date.now();
address = system.args[1];
page.open(address, function (status) {
    if (status !== 'success') {
        console.log('FAIL to load the address');
    } else {
        t = Date.now() - t;
        console.log('Loading time ' + t + ' msec');
    }
    phantom.exit();
});

并使用 'phantomjs test.js http://google.com' 运行它,它可以正常工作.

但是在这个小的 python 脚本中通过 selenium 运行 PhantomJS 会产生错误:

from selenium import webdriver
browser = webdriver.PhantomJS()
browser.get('http://seleniumhq.org')

python test.py

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    browser.get('http://seleniumhq.org/')
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 176, in get
    self.execute(Command.GET, {'url': url})
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 162, in execute
    response = self.command_executor.execute(driver_command, params)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 350, in execute
    return self._request(url, method=command_info[0], data=data)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 382, in _request
    resp = self._conn.getresponse()
  File "/usr/lib/python2.7/httplib.py", line 1045, in getresponse
    response.begin()
  File "/usr/lib/python2.7/httplib.py", line 409, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.7/httplib.py", line 373, in _read_status
    raise BadStatusLine(line)
httplib.BadStatusLine: ''

用 browser = webdriver.Firefox() 替换第二个 LOC 可以正常工作.

我在 Ubuntu 13.10 桌面上,同样的错误也出现在 Ubuntu 13.04 上.

Python:2.7PhantomJS:1.9.2

我在这里做错了什么?

推荐答案

似乎在较新的 Selenium 中引入了一些问题,请参阅

http://code.google.com/p/selenium/issues/detail?id=6690

通过使用我得到了一些进一步的使用

pip install selenium==2.37

避免上面的堆栈跟踪.driver.save_screenshot('foo.png') 仍然存在问题,导致文件为空.
