[英]Selenium::WebDriver::Error::UnknownError: unknown error: Chrome failed to start: exited abnormally
I'm installing chrome driver from the docker file.我正在从 docker 文件安装 chrome 驱动程序。 Base image is ruby.基本图像是 ruby。
Here's my docker file:这是我的 docker 文件:
FROM ruby:2.7.2
# install packages
RUN apt-get update && apt-get install -y \
curl \
build-essential \
libpq-dev &&\
curl -sL https://deb.nodesource.com/setup_10.x | bash - && \
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && \
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
apt-get update && apt-get install -y nodejs yarn
# We need wget to set up the PPA and xvfb to have a virtual screen and unzip to install the Chromedriver
RUN apt-get install -y wget xvfb unzip
# Set up the Chrome PPA
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list
# Update the package list and install chrome
RUN apt-get update -y
RUN apt-get install -y google-chrome-stable
ENV CHROME_BIN=/usr/bin/google-chrome
# Install bundler
RUN gem install bundler
RUN bundle config path /usr/local/bundle
# Make work directory
RUN mkdir -p /myapp/gatherer
WORKDIR /myapp/gatherer
# copy gem files
COPY ./app/Gemfile /myapp/Gemfile
COPY ./app/Gemfile.lock /myapp/Gemfile.lock
# Install bundle
RUN gem update bundler
RUN bundle check || bundle install
# copy .json and .lock files
COPY ./app/package.json /myapp/package.json
COPY ./app/yarn.lock /myapp/yarn.lock
# COPY all files
COPY ./app /myapp
#install yarn
RUN yarn install
But after running the test using bundle exec rspec
I get this error:但是在使用bundle exec rspec
运行测试后,我得到了这个错误:
1.3) Failure/Error: Unable to infer file and line number from backtrace
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.)
Here's how I'm configuring the chrome:这是我配置 chrome 的方式:
browsers: ['ChromeHeadlessNoSandbox'],
customLaunchers: {
ChromeHeadlessNoSandbox: {
base: 'ChromeHeadless',
flags: ['--headless', '--disable-gpu','--no-sandbox','--disable-dev-shm-usage']
}
},
How can I resolve this error?我该如何解决这个错误? When I run the code locally I'm not getting this error, only getting error in docker-image.当我在本地运行代码时,我没有收到此错误,仅在 docker-image 中收到错误。 Locally everything is running fine.在本地一切都运行良好。

WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser WebDriverException:未知错误:尝试启动 Chrome 浏览器时 DevToolsActivePort 文件不存在
The error I was getting was because of the test.我得到的错误是因为测试。 I changed the rails test, and the error got resolved.我更改了 rails 测试,错误得到解决。
The test because of which I was getting an error:因为我得到一个错误的测试:
it "can re-order a task", :js do
visit(project_path(project))
find("#task_3")
within("#task_3") do
click_on("Up")
end
expect(page).to have_selector("tbody:nth-child(2) .name", text: "Take Notes")
#END:P1
#START:P2
visit(project_path(project))
find("#task_2")
within("#task_2") do
expect(page).to have_selector(".name", text: "Use Telescope")
end
end
After removing :js
, error got resolved:删除:js
后,错误得到解决:
it "can re-order a task" do
visit(project_path(project))
find("#task_3")
within("#task_3") do
click_on("Up")
end
expect(page).to have_selector("tbody:nth-child(2) .name", text: "Take Notes")
#END:P1
#START:P2
visit(project_path(project))
find("#task_2")
within("#task_2") do
expect(page).to have_selector(".name", text: "Use Telescope")
end
end
