PyCharm无法连接到GhostDriver [英] PyCharm unable to connect to GhostDriver

问题描述

我有一个单元测试，当我通过python manage.py test运行它时通过了，但是当我从PyCharm内部运行时失败了.

I have a unit test that is passing when I run it via python manage.py test, but failing when I run it from within PyCharm.

def test_alpha(self):
    from selenium.webdriver.common.utils import free_port
    from selenium import webdriver

    driver = webdriver.PhantomJS(executable_path=PHANTOMJS_PATH, port=free_port())
    driver.quit()

从PyCharm运行时遇到的异常是

The exception I get when running from PyCharm is

WebDriverException: Message: 'Can not connect to GhostDriver' 

我花了很多时间来研究这个问题，并且我注意到当我手动指定端口时，测试会在PyCharm中通过.

I've spent a fair amount of time digging into this problem, and I've noticed that when I specify a port manually the test passes within PyCharm.

# suppose 50000 happens to be a free port on your computer
driver = webdriver.PhantomJS(executable_path=PHANTOMJS_PATH, port=50000)

要快速回顾一下:

• 通过python manage.py test
通过测试
• 如果手动指定端口，则测试会通过PyCharm
• 如果port=free_port()
，则在PyCharm中测试失败

• Test passes with python manage.py test
• Test passes in PyCharm if port is specified manually
• Test fails in PyCharm if port=free_port()

PyCharm在做什么，这使得测试无法连接到Ghostdriver?

What is PyCharm doing that is making the test unable to connect to Ghostdriver?

# For convenience, the `free_port()` code snippet is here
# selenium.webdriver.common.utils.freeport

def free_port():
    free_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    free_socket.bind(('127.0.0.1', 0))
    free_socket.listen(5)
    port = free_socket.getsockname()[1]
    free_socket.close()
    return port 

推荐答案

终端设置中的某些内容可能会影响联网.

Something in your terminal setup probably influences the networking.

尝试从您的终端启动PyCharm :

open -a /Applications/PyCharm.app/

然后再次运行测试，它应该通过.

Then run the test again, and it should pass.
