Github npm 启动后操作不起作用

Question

我有一个非常简单的配置，以便运行在 Nextjs 应用程序中使用 Github 操作对 Cypress 进行端到端测试。当它到达 npm start 命令时，虽然它似乎可以工作，因为它给出了正确的输出：> Ready on http://localhost:3000，但该步骤仍处于挂起状态，而不会前进到下一步。

关于如何解决这个问题有什么建议吗？

以下 github 个操作配置 (.github/workflows/nodejs.yml)：

name: Node CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [8.x, 10.x, 12.x]

    steps:
    - uses: actions/checkout@v1
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v1
      with:
        node-version: ${{ matrix.node-version }}
    - name: npm install, build, and test
      run: |
        npm ci
        npm run build --if-present
        npm start
        npx wait-on http://localhost:3000
      env:
        CI: true
    - name: Run Cypress
      run: |
        npx cypress run
      env:
        CI: true

使用控制运算符 & 对我有用。请尝试以下操作。

    - name: npm install, build, and test
      run: |
        npm ci
        npm run build --if-present
        npm start & npx wait-on http://localhost:3000
      env:
        CI: true

来自man bash

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0. These are referred to as asynchronous commands. Commands separated by a ; are executed sequentially; the shell waits for each command to terminate in turn. The return status is the exit status of the last command executed.
