Github 操作：没有这样的文件或目录错误

Question

背景

我正在尝试让 Github Action 与 Windows 和 Bakeware 一起使用，因为我正在尝试使用它创建一个版本。

但是，我在创建文件夹时遇到了意外问题。

代码

以下是一个 github 操作，它是该问题的最小工作示例。 基本上，所有步骤都有效，除了创建单个文件夹：

name: build

env:
  MIX_ENV: test
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:

  build:
    name: Build on Windows
    runs-on: windows-2019
    env: 
        CC: gcc
        MAKE: make

    steps:
    - uses: actions/checkout@v2
    - uses: erlef/setup-beam@v1
      with:
        elixir-version: '1.13.x' # Define the elixir version [required]
        otp-version: '24.2.x' # Define the OTP version [required]
    
    - name: Install choco
      shell: powershell
      run: |
        Set-ExecutionPolicy -ExecutionPolicy Bypass
        Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

    - name: Install bakeware dependencies
      shell: powershell
      run: choco install -y zstandard make 

    - name: Install Dependencies
      shell: powershell
      run: mix deps.get
 
    - name: Run credo code analyser
      shell: powershell
      run: mix credo --strict

我什至正在使用 powershell 来执行此操作（尽管我不确定是否需要这样做）。

问题

但是我的 GitHub Actions 代码返回此错误：

==> bakeware

mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj"

mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/launcher"

mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress"

mkdir: cannot create directory 'd:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress': No such file or directory

make: *** [Makefile:70: d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress] Error 1

could not compile dependency :bakeware, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile bakeware", update it with "mix deps.update bakeware" or clean it with "mix deps.clean bakeware"

** (Mix) Could not compile with "make" (exit status: 2).

对于细心的读者，您会注意到部分内容：

mkdir: cannot create directory 'd:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress': No such file or directory

研究

通过稍微更改 GitHub 操作并添加一个额外的步骤，我能够检查一些行为：

    - name: Compile everything
      shell: powershell
      run: |
        mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj" 
        mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/launcher"
        mkdir "d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress"
        ls .\_build\test\lib\bakeware\obj\zstd\lib\decompress
        Test-Path -Path "d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress"
        mix deps.compile --all
        mix compile
      env: 
        CC: C:\ProgramData\Chocolatey\bin\gcc.exe
        MAKE: C:\ProgramData\Chocolatey\bin\make.exe
  

在这个 sn-p 中，我手动创建所需的文件夹，然后对它们进行断言。输出如下：

    Directory: D:\a\market_manager\market_manager\_build\test\lib\bakeware


Mode                LastWriteTime         Length Name                                                                  
----                -------------         ------ ----                                                                  
d-----         2/2/2022  11:06 AM                obj                                                                   
d-----         2/2/2022  11:06 AM                launcher                                                              


    Directory: D:\a\market_manager\market_manager\_build\test\lib\bakeware\obj\zstd\lib


Mode                LastWriteTime         Length Name                                                                  
----                -------------         ------ ----                                                                  
d-----         2/2/2022  11:06 AM                decompress                                                            
True

我们可以看到：

• 所有目录都已创建
• Test-Path 返回True，这意味着'd:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress' 确实存在。

这只会让我更加困惑，因为错误仍然没有改变：

mkdir: cannot create directory 'd:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress': No such file or directory
make: *** [Makefile:70: d:/a/market_manager/market_manager/_build/test/lib/bakeware/obj/zstd/lib/decompress] Error 1
could not compile dependency :bakeware, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile bakeware", update it with "mix deps.update bakeware" or clean it with "mix deps.clean bakeware"
** (Mix) Could not compile with "C:\ProgramData\Chocolatey\bin\make.exe" (exit status: 2).

当我使用的每个命令都毫无疑问地显示该文件夹确实存在时，我真的无法理解错误No such file or directory。

问题

为什么我总是收到这个错误？

回答

在我的头撞墙几天之后，我想我终于想通了。 该命令失败是因为 cmd mkdir 的行为方式，因为它与 poewrshell 中的行为不同。

通过将 Makefile 更改为仅在文件夹不存在时创建文件夹，我能够解决问题，同时仍保持向后兼容性，这是我的要求之一。

我已经提交了包含此修复程序的 PR，在撰写本文时，我很高兴地宣布它已经合并到 master：
