node.js - 启动服务器并测试 "server closed unexpectedly"

Question

我正在使用start-server-and-test package在我的 Azure 管道上启动服务器来运行 Cypress。

这是我用来启动一切的 yarn 命令:yarn cy:build:workspace

"cy:build:workspace": "yarn cy:clean && start-server-and-test start http://localhost:8080 cy:run:workspace"

我正在 Azure 环境中运行 NODE_VERSION:“12.10.0”。

"C:\windows\system32\cmd.exe" /D /E:ON /V:OFF /S /C "CALL "d:\a\_temp\ce28689e-eef6-4eeb-bad2-82310f748e1b.cmd""
yarn run v1.22.4
$ yarn cy:clean && start-server-and-test start http://localhost:3000 cy:run:workspace
$ rimraf cypress/reports/*
1: starting server using command "npm run start"
and when url "[ 'http://localhost:3000' ]" is responding with HTTP status code 200
running tests using command "npm run cy:run:workspace"

本地一切都在运行，对于服务器在 Azure 环境中停止的原因有什么建议吗？

如果您使用的是“react-scripts”，请检查您的 package.json:“3.4.1”降级到 3.4.0

还要验证此链接以将start-server-and-test与yarn一起使用，您需要添加类似字符串的一些yarn命令 https://github.com/bahmutov/start-server-and-test#note-for-yarn-users
