Github操作-R包found检查“未找到PhantomJS”

Question

我正在使用GitHub动作作为我的R包的CI。我正在尝试在包中同时使用testthat和shinytest。我已经根据shinytest文档正确地设置了包结构。当我在RStudio中运行RStudio时，我的包(包括testthat和shinytest测试都能工作)。

我的GitHub操作.yaml工作流是：

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上失败，但在Ubuntu上工作。

我在Windows和Mac上遇到的错误是：

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

我不认为这是我的包裹或测试的问题。我认为我的.yaml有错误的配置。如何在我的工作流中使用PhantomJS解决这个问题？

简单的解决方案将是转到使用了PhantomJS的项目，并打开Github操作。我们将进入shiny项目，准确地说是：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，只是为了确保PhantomJS本地化是已知的，或者是否应该安装它。

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

如果没有详细的日志以及在Query dependencies步骤中安装了哪些依赖项(Query dependencies)的信息，就很难调查这个问题。似乎根本没有安装PhantomJS依赖项。工作流在ubuntu-20.04上成功，因为运行程序PhantomJS安装了开箱即用吗？。您可以看到在提供的运行程序类型这里上安装的所有软件。上面工作流中使用的其他运行程序类型(windows-latest和macOS-latest)缺少PhantomJS。这就是为什么您的工作流在Windows和MacOS上失败而在Ubuntu上成功的原因。
