Docker錯誤：standard_init_linux.go:228：exec用戶行程導致：exec格式錯誤

我能夠從 arm64 的 M1 Macbook 成功構建多架構映像。這是我的 docker 檔案并嘗試從 raspberrypi aarch64/arm64 運行，我在運行影像時收到此錯誤：standard_init_linux.go:228: exec 用戶行程導致：exec 格式錯誤

也用 python 檔案編輯帖子：

uj5u.com熱心網友回復：

在 MacOS 上構建的“多架構”Python 解釋器旨在針對 MacOS-on-Intel 和 MacOS-on-Apple's-arm64。

與 Linux-on-Apple 的 arm64或Linux-on-aarch64絕對沒有二進制兼容性。無論架構是否匹配，您都無法在 Linux 上運行 MacOS 可執行檔案。
