Github 操作 - R 包 R-CMD-检查 "PhantomJS not found"

Question

我正在对我的 R 包的 CI 使用 GitHub 操作。我正在尝试在我的包中同时使用 testthat 和 shinytest。我根据 shinytest 文档正确设置了包结构。当我在 RStudio 中运行 R-CMD-CHECK 时，我的包（包括 testthat 和 shinytest 测试有效）。

我的 GitHub 操作 .yaml 工作流程是：

on:
  push:
    branches:
      - main
      - master
  pull_request:
    branches:
      - main
      - master

name: R-CMD-check

jobs:
  R-CMD-check:
    runs-on: ${{ matrix.config.os }}

    name: ${{ matrix.config.os }} (${{ matrix.config.r }})

    strategy:
      fail-fast: false
      matrix:
        config:
          - {os: windows-latest, r: 'release'}
          - {os: macOS-latest, r: 'release'}
          - {os: ubuntu-20.04, r: 'release', rspm: "https://packagemanager.rstudio.com/cran/__linux__/focal/latest"}
          - {os: ubuntu-20.04, r: 'devel', rspm: "https://packagemanager.rstudio.com/cran/__linux__/focal/latest"}

    env:
      R_REMOTES_NO_ERRORS_FROM_WARNINGS: true
      RSPM: ${{ matrix.config.rspm }}

    steps:
      - uses: actions/checkout@v2

      - uses: r-lib/actions/setup-r@v1
        with:
          r-version: ${{ matrix.config.r }}

      - uses: r-lib/actions/setup-pandoc@v1

      - name: Query dependencies
        run: |
          install.packages('remotes')
          saveRDS(remotes::dev_package_deps(dependencies = TRUE), ".github/depends.Rds", version = 2)
          writeLines(sprintf("R-%i.%i", getRversion()$major, getRversion()$minor), ".github/R-version")
        shell: Rscript {0}

      - name: Cache R packages
        if: runner.os != 'Windows'
        uses: actions/cache@v2
        with:
          path: ${{ env.R_LIBS_USER }}
          key: ${{ runner.os }}-${{ hashFiles('.github/R-version') }}-1-${{ hashFiles('.github/depends.Rds') }}
          restore-keys: ${{ runner.os }}-${{ hashFiles('.github/R-version') }}-1-

      - name: Install system dependencies
        if: runner.os == 'Linux'
        run: |
          while read -r cmd
          do
            eval sudo $cmd
          done < <(Rscript -e 'writeLines(remotes::system_requirements("ubuntu", "20.04"))')

      - name: Install dependencies
        run: |
          remotes::install_deps(dependencies = TRUE)
          remotes::install_cran("rcmdcheck")
        shell: Rscript {0}

      - name: Check
        env:
          _R_CHECK_CRAN_INCOMING_REMOTE_: false
        run: rcmdcheck::rcmdcheck(args = c("--no-manual", "--as-cran"), error_on = "warning", check_dir = "check")
        shell: Rscript {0}

      - name: Upload check results
        if: failure()
        uses: actions/upload-artifact@main
        with:
          name: ${{ runner.os }}-r${{ matrix.config.r }}-results
          path: check

当我提交到存储库时，检查在 Windows 和 Mac OS 上失败但在 Ubuntu.

上有效

我在 Windows 和 Mac OS 上遇到的错误是：

> test_check("mypackage")
-- 1. Error: application works (@test-appdir.R#6)  -----------------------------
PhantomJS not found.

我认为这不是我的包或测试的问题。我认为我的 .yaml 配置有误。 如何在我的工作流程中解决 PhantomJS 的这个问题？

Answer 1

如果没有详细的日志并且没有关于在 Query dependencies 步骤中安装了哪些依赖项 (remotes) 的信息，很难调查该问题。似乎根本没有安装 PhantomJS 依赖项。工作流在 ubuntu-20.04 上成功，因为运行器 has PhantomJS installed out-of-the-box. You can see all the installed software on provided runner types here. The other runner types used in the workflow above (windows-latest and macOS-latest) 缺少 PhantomJS。这就是为什么您的工作流程在 Windows 和 MacOS 上失败但在 Ubuntu.

上成功的原因

简单的解决方案是转到使用 PhantomJS 并打开 Github 操作的项目。我们将转到 shiny 项目并准确地： https://github.com/rstudio/shiny/blob/master/.github/workflows/R-CMD-check.yaml

我们可以在那里发现：

      - name: Install system dependencies
        if: runner.os == 'Linux'
        env:
          RHUB_PLATFORM: linux-x86_64-ubuntu-gcc
        run: |
          Rscript -e "remotes::install_github('r-hub/sysreqs')"
          sysreqs=$(Rscript -e "cat(sysreqs::sysreq_commands('DESCRIPTION'))")
          sudo -s eval "$sysreqs"
      - name: Install dependencies
        run: |
          remotes::install_deps(dependencies = TRUE)
          remotes::install_cran("rcmdcheck")
        shell: Rscript {0}

      - name: Find PhantomJS path
        id: phantomjs
        run: |
          echo "::set-output name=path::$(Rscript -e 'cat(shinytest:::phantom_paths()[[1]])')"
      - name: Cache PhantomJS
        uses: actions/cache@v1
        with:
          path: ${{ steps.phantomjs.outputs.path }}
          key: ${{ runner.os }}-phantomjs
          restore-keys: ${{ runner.os }}-phantomjs
      - name: Install PhantomJS
        run: >
          Rscript
          -e "if (!shinytest::dependenciesInstalled()) shinytest::installDependencies()"

我们可以很容易地检查是否有单独的代码块，以确保 PhantomJS 本地化已知或是否应该安装。

您可以将这部分代码粘贴到您的 yaml 文件中。然而，最好的方法可能是遵循 shiny 项目的流程，
