我正在尝试使用firefox让我的无头覆盆子pi上的selenium。我在带有chrome的Windows上运行良好。这是我的版本：
uname -a Linux megabyte.thompco.com 4.9.59-v7+ #1047 SMP Sun Oct 29
12:19:23 GMT 2017 armv7l GNU/Linux
which firefox
/usr/bin/firefox
firefox --version
Mozilla Firefox 52.5.2
./geckodriver_32 --version
geckodriver 0.19.1

我认为我有兼容版本的驱动程序和firefox（这似乎有效）：
./geckodriver_32 -b /usr/bin/firefox
1516245181824 geckodriver INFO geckodriver 0.19.1
1516245181881 geckodriver INFO Listening on 127.0.0.1:4444
当我运行以下代码时：
def __init__(self, tag, user_name, password, driver_location, headless):
logger = logging_utils.get_logger()
logging_utils.start_function(logger, user_name=user_name)
self.tag = tag
self.user_name = user_name
self.password = password
self.cards = []
driver_options = Options()
driver = None
try:
if "chrome" in driver_location.lower():
if headless:
driver_options.add_argument("--headless")
driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver.exe"),
chrome_options=driver_options)
elif "gecko" in driver_location.lower():
binary = FirefoxBinary("/usr/bin/firefox")
driver_options.binary = binary
profile = webdriver.FirefoxProfile()
driver_options.profile = profile
driver_options.set_headless(headless)
driver = webdriver.Firefox(firefox_binary=binary,
firefox_profile=profile,
executable_path=os.path.abspath(driver_location),
firefox_options=driver_options)
我收到此错误：
Traceback (most recent call last):
File "/mnt/usbdrive/python/AmexOfferChecker/amexParser.py", line 105, in __init__

File "/home/jordan/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 158, in __init__

response = self.execute(Command.NEW_SESSION, parameters)

欢迎任何建议！
我修改了我的“gecko”部分，如下所示：
options = Options()
options.add_argument('-headless')
print driver_location
print os.path.abspath(driver_location)
driver = Firefox(executable_path=os.path.abspath(driver_location),
firefox_options=options)
print "Driver has been loaded!"
现在我收到了这个错误：

我确实看到了这个错误： 在Linux上，即使无头模式不使用它们，您的系统上也需要某些库 - 因为Firefox链接它们。有关详细信息和修复进度，请参阅bug 1372998。 我添加了建议的库：
sudo apt-get install libgtk-3-0 libdbus-glib-1-2 xvfb
但我仍然得到同样的例外。
我也尝试了同样的错误（注意创建了调试文件，但是空的）：
options = Options()
options.add_argument('--headless')
profile = webdriver.FirefoxProfile()
profile.set_preference("logs/webdriver.log", "/tmp/firefox_console")
binary = FirefoxBinary(firefox_path="/usr/bin/firefox",
log_file=open("/tmp/firefox_output", "wb"))
driver = webdriver.Firefox(firefox_profile=profile,
firefox_binary=binary,
options=options,
executable_path=os.path.abspath(driver_location))
最后为seleniuim开启了日志记录（这对任何人都意味着什么？）：

最后得到了这个，但是使用了镀铬和镀铬。 您必须先安装chrome：

接下来从这里下载了debian软件包： https://packages.debian.org/stretch/armhf/chromium-driver/download 解压缩文件“chromedriver”：
sudo apt-get install chromium-browser
其余代码不变。注意
mkdir tmp
dpkg-deb -R chromium-driver_63.0.3239.84-1_deb9u1_armhf.deb tmp
cp /usr/local/bin/chromedriver .
mv chromedriver chromedriver_arm_64
很好（“ - 无头”可能也可以 - 我还没试过）。我肯定希望有人在花费尽可能多的时间之前发现这一点！

您也可以尝试声明DISPLAY变量，它尤其适用于远程连接。 在终端上运行此命令：
export DISPLAY=:0.0
