Travis CI:启动rails服务器

Question

我需要在Travis上启动rails服务器来运行集成测试.我已将此添加到配置文件中:

before_script:
  - psql -c 'create database scalia_test;' -U postgres
  - "bundle exec rails server -p 3000 &"

但是,我仍然收到赛普拉斯的错误:

http://localhost:3000/users/sign_in
We attempted to make an http request to this URL but the request failed without a response.
We received this error at the network level:
  > Error: connect ECONNREFUSED 127.0.0.1:3000
Common situations why this would fail:
  - you don't have internet access
  - you forgot to run / boot your web server
  - your web server isn't accessible
  - you have weird network configuration settings on your computer
The stack trace for this error is:
Error: connect ECONNREFUSED 127.0.0.1:3000
    at Object.exports._errnoException (util.js:1024:11)
    at exports._exceptionWithHostPort (util.js:1047:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1150:14)

有人知道如何在Travis上启动Rails服务器吗？

可能该端口正在使用中。输入lsof -i :8000终端以查看该端口是否正在使用您可以尝试使用不同的端口启动服务器，例如rails server -p 3050
