GitHubAction生成的Cargo構建工件不在本地執行

我正在嘗試構建一個簡單的“Hello World”Rust 程式并使用構建程序的工件創建一個 GitHub 版本。使用的工具鏈是stable-x86_64-unknown-linux-gnu，cargo build無論是cargo run在本地運行還是在本地都沒有問題。可以在此處找到發布本身以及生成的二進制檔案。可以在此處找到 GitHub 操作日志。

該操作能夠創建發布，但生成的二進制檔案無法在我的系統上執行（Ubuntu 21.10 impish）。在以下命令中，下載的二進制檔案的名稱是x86_64-unknown-linux-gnu.

$ bash x86_64-unknown-linux-gnu
x86_64-unknown-linux-gnu: x86_64-unknown-linux-gnu: cannot execute binary file

$ ./x86_64-unknown-linux-gnu
bash: ./x86_64-unknown-linux-gnu: Permission denied

嘗試使用 添加權限后chmod u x x86_64-unknown-linux-gnu，上述命令不產生任何輸出。

uj5u.com熱心網友回復：

我找到了解決方案。顯然，UPX 以某種方式破壞了 Linux 可執行檔案。但是，當我嘗試構建 Windows 可執行檔案時，UPX 仍然可以正常作業。為了修復我的 GitHub Action 作業流程，我進行了以下更改：

# old
- name: Run UPX
  uses: crazy-max/ghaction-upx@v1
  with:
    version: latest
    files: target/release/${{ env.PROJECT_NAME }}
    args: --brute

# new
- name: Strip artifact
  run: strip target/release/${{ env.PROJECT_NAME }}

- name: Run UPX
  run: echo "Not supported on linux platform"
