我正在尝试设置一个 jenkins 服务器以在 Amazon Linux 上使用 Selenium-webdriver(3.142.0) 和 ruby(2.3.7) 托管我的自动化框架。如果我尝试使用我的脚本调用 chromedriver，它会说，
"Selenium::WebDriver::Error::UnknownError: unknown error: Chrome failed to start: exited abnormally (unknown error: DevToolsActivePort file doesn't exist) (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.) (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 4.14.104-95.84.amzn2.x86_64 x86_64)".
我已将我的 chromedriver 放在 '/var/lib/jenkins/driver/chromedriver' 下，并在 .bashrc 中设置相同的 PATH，还为它创建了一个指向 '/usr/bin/google-chrome 的符号链接(symbolic link)'.以下是我正在使用的机器的详细信息:
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"```
require 'selenium-webdriver'
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument("--disable-dev-shm-usage");
options.add_argument('--no-sandbox')
driver = Selenium::WebDriver.for :chrome, options: options
>Expected result: Browser should be invoked.
>Actual result:
Exits with the error "The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed."
