电子应用程序Travis CI构建失败

Question

我正在使用Electron构建使用JavaScript的跨平台应用程序。虽然让Travis CI能够成功构建，但我遇到了一些麻烦。

的docs on setting it up说，我.travis.yml应类似于此：

addons: 
    apt: 
    packages: 
     - xvfb 

install: 
    - export DISPLAY=':99.0' 
    - Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 & 

我现在.travis.yml看起来是这样的：

language: node_js 

node_js: 
    - "node" 

addons: 
    apt: 
    packages: 
     - xvfb 

before_install: 
    - cd src/ 

install: 
    - npm install 

before_script: 
    - export DISPLAY=':99.0' 
    - Xvfb :99 -screen 0 1024x768x24 +extension GLX +extension RANDR > /dev/null 2>&1 & 

script: 
    - npm test 

这里是一个构建日志（在引擎收录，因为它是巨大的）：https://pastebin.com/8N4P2S7Y。重要的部分如下：

> ThemeCreator@0.1.0 test /home/travis/build/blabel3/ThemeCreator/src 
> electron . 

Xlib: extension "RANDR" missing on display ":99.0". 
Xlib: extension "RANDR" missing on display ":99.0". 


No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself. 
Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received 

The build has been terminated 

非常感谢你们提供的任何帮助！

它应该可以只用sh -e /etc/init.d/xvfb start

目前我使用以下配置运行xvfb的，它工作正常。

os: 
    - linux 

language: node_js 

node_js: 
    - "7.7" 

before_script: 
    - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then export DISPLAY=:99.0; fi 
    - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then sh -e /etc/init.d/xvfb start; fi 
    - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then sleep 3; fi 

script: 
    - node --version 
    - npm --version 
    - npm install 
    - npm run e2e
