我有一个简单的工作流程：

name: Test CI

env:
  path_to_watch_for_commits: 'testdir/testfile'

on:
  push:
    branches:
      - master
    paths:
      - ${{ env.path_to_watch_for_commits }}

  workflow_dispatch:

jobs:
  build:
    runs-on:  ubuntu

    steps:
      - uses: actions/checkout@v2

我想path_to_watch_for_commits在路径中使用变量。但这个语法是错误的。我也尝试过${{ path_to_watch_for_commits }}但$path_to_watch_for_commits没有结果。我究竟做错了什么？
