篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Headless Chrome Circle CI - 错误：spawn /usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/bin/java ENOENT相关的知识，希望对你有一定的参考价值。

我试图在无头镀铬的Circle CI中进行测试。我使用的是selenium服务器版本3.8.1和chromedriver版本2.34

protractor_conf.js由chrome功能组成：

var chromeCapabilities = {
   browserName: 'chrome',
   chromeOptions: {  
     args: [
     'headless','--show-fps-counter=false', '--remote-debugging-port=2222', '--disable-gpu'
     ]
   }
}

我的sh脚本包含以下用于webdriver-manager的命令，然后运行测试：

./node_modules/protractor/bin/webdriver-manager clean
./node_modules/protractor/bin/webdriver-manager update --gecko false --versions.standalone 3.8.1 --versions.chrome 2.34
./node_modules/protractor/bin/webdriver-manager start &

echo "*** Run script for e2e tests"
gulp e2e

我在m circle.yml中添加了这些以安装最新版本的稳定chrome并启动无头监听localhost：

dependencies:
    post:
     # Install the latest Chrome
      - curl -L -o google-chrome.deb https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
      - sudo dpkg -i google-chrome.deb
      - sudo sed -i 's|HERE/chrome"|HERE/chrome" --disable-setuid-sandbox|g' /opt/google/chrome/google-chrome
      - rm google-chrome.deb
    before_install:
      - google-chrome --headless --remote-debugging-port=2222 --disable-gpu http://localhost &

所以，当我现在运行我的构建时，测试根本不运行。日志说：

使用的版本：

  • Chrome浏览器版本：Google Chrome 63.0.3239.132
  • 量角器：v5.2.2
  • Chromedriver拉链：2.34
  • Selenium独立：3.8.1
  • 圈CI：1.0

我错过了什么？任何帮助，将不胜感激。

答案

解：

circle ci上安装的默认java版本是1.7。我强迫它安装1.8 jdk：

  • 去圈ci构建测试命令并使用：java --version命令检查安装的java版本。那里有v1.7表格。
  • 然后，我修改我的Dockerfile使用jdk 8使用：FROM openjdk：8这将覆盖安装的v1.7并强制使用1.8解决了我的问题。
