Docker找不到文件

Question

我有这个Dockerfile：

如您所见，我正在编译一个go应用程序。当我尝试运行最后一个命令时，它失败了，并显示以下错误：

/bin/sh: 1:  /syzkaller-git/gopath/src/github.com/google/syzkaller/bin/syz-manager: not found

我已经检查了文件是否真的存在，它确实存在。我试着上网找，但没什么用。我还尝试将此特定命令从单行RUN命令中分离出来，但无济于事。

您已经位于此路径$SYZKALLER/gopath/src/github.com/google/syzkaller/

Dockerfile

cd $SYZKALLER/gopath/src/github.com/google/syzkaller/ && \

并且您正在尝试访问该路径中的文件

./syzkaller-git/gopath/src/github.com/google/syzkaller/bin/syz-manager

看起来您需要将上面的内容更新为绝对路径，或者使用下面的命令

./bin/syz-manager
