复合github动作，自动cd到actions目录？

Question

我正在尝试设置一个 github 操作机器人，该机器人在操作运行时使用合成来构建。值得注意的是，这不是必需的，而且我知道 ncc 也会实现同样的目标，但我很好奇是否有可能以可持续的方式实现这项工作。

对于某些上下文，我正在尝试使用 yaml 脚本运行我的alita-moore/EIP-Bot私人操作...

name: "Auto Merge EIP"
description: "A bot that lints EIP edits, finds common errors, and can auto-merge"
inputs:
  GITHUB-TOKEN:
    description: |-
      The Github token to be used by this bot when merging, posting comments, or requesting reviewers
    required: true
  VERSION:
    description: version of the action; this is required because of how actions work
    required: true

runs:
  using: "composite"
  steps:
    - run: cd /home/runner/work/_actions/alita-moore/EIP-Bot/${{ inputs.VERSION }} && npm ci && npm run build && GITHUB_TOKEN=${{ inputs.GITHUB-TOKEN }} node build/index.js
      shell: bash

目前，这与给定存储库的工作流程 yaml 一起运行

on: [pull_request]

jobs:
  auto_merge_bot:
    runs-on: ubuntu-latest
    name: EIP Auto-Merge Bot
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Setup Node.js Enviornment
        uses: actions/setup-node@v2
        with:
          node-version: '14'
      - name: auto-merge-bot
        uses: alita-moore/EIP-Bot@1.0.8
        id: auto-merge-bot
        with:
          GITHUB-TOKEN: ${{ secrets.TOKEN }} 
          VERSION: 1.0.8

你可能已经注意到，在npm ci && npm run build我首先必须cd /home/runner/work/_actions/alita-moore/EIP-Bot/${{ inputs.VERSION }}

如果你不这样做，它会抛出以下错误

Run alita-moore/EIP-Bot@1.0.1
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /home/runner/work/EIPs/EIPs/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/home/runner/work/EIPs/EIPs/package.json'
npm ERR! enoent This is related to npm not being able to find a file.

有一个更好的方法吗？

您可以使用${{github.action_path}}包含操作定义文件的目录路径action.yaml：

[...]
runs:
  using: "composite"
  steps:
    - run: cd ${{github.action_path}} && npm ci && npm run build && GITHUB_TOKEN=${{ inputs.GITHUB-TOKEN }} node build/index.js
      shell: bash

github.action_path| string| 您的操作所在的路径。您可以使用此路径轻松访问与您的操作位于同一存储库中的文件。此属性仅在复合运行步骤操作中受支持。
