Any idea what is wrong? I've tried google without luck.

知道出了什么问题吗？我试过谷歌没有运气。

If you are running Firefox on a system with no display, make sure you use headless mode.

如果您在没有显示器的系统上运行 Firefox，请确保使用无头模式。

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)

Also, make sure you have compatible versions of Firefox, Selenium, and Geckodriver: https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html

另外，请确保您拥有兼容版本的 Firefox、Selenium 和 Geckodriver：https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html

This error message...

这个错误信息...

selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

...implies that the GeckoDriverwas unable to initiate/spawn a new WebBrowsing Sessioni.e. Firefox Browsersession.

...暗示GeckoDriver无法启动/生成新的WebBrowsing 会话，即Firefox 浏览器会话。

Your main issue is the incompatibilitybetween the version of the binaries you are using as follows:

您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：

Your GeckoDriverversion is 0.22.0.
Release Notes of GeckoDriver v0.21.0 (2018-06-15)clearly mentions the following:
- Firefox 57 (and greater)
- Selenium 3.11 (and greater)
Your Firefoxversion is 52.9.0.

您的GeckoDriver版本是0.22.0。
GeckoDriver v0.21.0 (2018-06-15) 的发行说明清楚地提到了以下内容：
- Firefox 57（及更高版本）
- Selenium 3.11（及更高版本）
您的Firefox版本是52.9.0。

So there is a clear mismatch between GeckoDriver v0.22.0and the Firefox Browser v57

所以GeckoDriver v0.22.0和Firefox Browser v57之间存在明显的不匹配

Solution

解决方案

Upgrade GeckoDriverto GeckoDriver v0.22.0level.
GeckoDriver is present in the specified location.
GeckoDriver is having executable permission for non-rootusers.
Upgrade Firefoxversion to Firefox v62.0.2levels.
Cleanyour Project Workspacethrough your IDEand Rebuildyour project with required dependencies only.
If your base Web Clientversion is too old, then uninstall it through Revo Uninstallerand install a recent GA and released version of Web Client.
Execute your Selenium Testas a non-root user.

升级GeckoDriver到GeckoDriver v0.22.0水平。
GeckoDriver 存在于指定位置。
GeckoDriver 对非 root用户具有可执行权限。
将Firefox版本升级到Firefox v62.0.2级别。
清理你的项目工作，通过你的IDE和重建仅需要依赖你的项目。
如果您的基本Web Client版本太旧，请通过Revo Uninstaller卸载它并安装最新的 GA 和发布版本的Web Client。
以非 root 用户身份执行您的Selenium 测试。

I was on headless mode, using correct versions of everything, and the only way to get out of this error message was notto execute the selenium test as root

我处于无头模式，使用正确版本的所有内容，摆脱此错误消息的唯一方法是不要以 root 身份执行 selenium 测试

Yes checked Start Xvfb before the build can fix the problem, but if you have a job like a pipeline or multibranch pipeline this option is not visible. In the node of your Selenium grid that you go to execute the test you need:

是在构建可以解决问题之前选中 Start Xvfb，但如果您有像管道或多分支管道这样的工作，则此选项不可见。在您要执行测试的 Selenium 网格节点中：

1- Install Xvfb: apt install xvfb

1- 安装 Xvfb： apt install xvfb

2- Execute Xvfb: /usr/bin/Xvfb :99 -ac -screen 0 1024x768x8 & export DISPLAY=":99"

2- 执行 Xvfb： /usr/bin/Xvfb :99 -ac -screen 0 1024x768x8 & export DISPLAY=":99"

3- Rerun your node, for example: java -jar selenium.jar -role node -hub http://#.#.#.#:4444/grid/register -capabilities browserName=firefox,plataform=linux -host #.#.#.# -port 1991

3- 重新运行您的节点，例如： java -jar selenium.jar -role node -hub http://#.#.#.#:4444/grid/register -capabilities browserName=firefox,plataform=linux -host #.#.#.# -port 1991

I had the same problem, and realized that the real problem was some firefox dependencies not being installed inside the docker container I was testing in.

我遇到了同样的问题，并意识到真正的问题是我正在测试的 docker 容器中没有安装一些 Firefox 依赖项。
