Github actions actionscheckout@v2 lfs: true标志没有将指针转换为实际文件。

Question

这是我的github actions yml文件。

name: CI

on: [pull_request]

jobs:
  build_ios:
    name: Set up
    runs-on: ${{ matrix.os }}

    strategy:
      matrix:
        os: [self-hosted]
        node-version: [10.x]

    steps:
      - name: Checkout github repo (+ download lfs dependencies)
        uses: actions/checkout@v2
        with:
          lfs: true

运行之后，我希望所有的git lfs文件都能被下载、检查并准备好使用，但文件的内容却是：

version https://git-lfs.github.com/spec/v1
oid sha256:f23e4c2b1244bc93085dbccf17c447e54sca44650294648df128d58303e4eff
size 58951008

下面我附上实际的github动作日志，以备不时之需。

LFS对象似乎只能根据日志来获取。你需要检查LFS文件，以便将指针文件替换成对应的LFS文件。下面是一个修改后的尝试 actions.yml 基于在GitHub Actions上的搜索（之前从未使用过它）。

name: CI

on: [pull_request]

jobs:
  build_ios:
    name: Set up
    runs-on: ${{ matrix.os }}

    strategy:
      matrix:
        os: [self-hosted]
        node-version: [10.x]

    steps:
      - name: Checkout github repo (+ download lfs dependencies)
        uses: actions/checkout@v2
        with:
          lfs: true
      - name: Checkout LFS objects
        run: git lfs checkout

如果LFS对象还没有被获取，那么你可以替换为 git lfs checkout 与 git lfs pull.
