Github操作-R包R-CMD-Check“ PhantomJS not found”

如何解决Github操作-R包R-CMD-Check“ PhantomJS not found”

我正在将GitHub操作用于我的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文档正确设置了包结构。当我在RStudio中运行R-CMD-CHECK时，我的程序包（包括testthat和shinytest测试都有效）。

我的GitHub Actions .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，该检查在Windows和Mac OS上失败，但在Ubuntu上工作。

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.

我认为这与我的包裹或测试无关。我认为我的.yaml配置有误。 如何在工作流程中使用PhantomJS解决此问题？

解决方法

简单的解决方案是转到使用PhantomJS并打开Github Actions的项目。我们将转到shiny项目，确切地说是： https://github.com/rstudio/shiny/blob/master/.github/workflows/R-CMD-check.yaml

我们可以发现：

      - 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()"

我们可以轻松地检查是否有单独的代码块，只是为了确保知道PhantomJS本地化或应该安装它。

您可以将这部分代码粘贴到yaml文件中。但是，最好的方法可能是遵循shiny项目的开发流程，

如果没有详细的日志，也没有关于在remotes步骤中安装的依赖项（Query dependencies）的信息，则很难进行调查。似乎根本没有安装PhantomJS依赖项。由于运行者has PhantomJS installed out-of-the-box，工作流在ubuntu-20.04上成功完成。您可以在提供的运行程序类型here上查看所有已安装的软件。上面的工作流程中使用的其他运行器类型（windows-latest和macOS-latest）缺少PhantomJS。这就是为什么您的工作流程在Windows和MacOS上失败而在Ubuntu上成功的原因。
