docker-rust疑难

Question

在容器中安装rust ,在容器内是可以使用cargo的，但是在外部命令docker exec 容器名 cargo时：

OCI runtime exec failed: exec failed: unable to start container process: exec: "cargo": executable file not found in $PATH: unknown

我觉得可能是环境变量问题，所以在构建容器时加入了：RUN PATH=$PATH:$HOME/.cargo/env

或者是末尾ENTRYPOINT [' "source "$HOME/.cargo/env" ']

我还尝试过 docker exec -it ubuntu source "$HOME/.cargo/env" &&cargo

OCI runtime exec failed: exec failed: unable to start container process: exec: "source": executable file not found in $PATH: unknown
docker run -e也曾尝试过，同样无效
docker exec -it ubuntu /bin/bash source "$HOME/.cargo/env" &&cargo
/bin/bash: source: No such file or directory

希望有人能帮我解决这个问题！可以用命令或者Dockerfile实现它

OCI runtime exec failed: exec failed: unable to start container process: exec: "cargo": executable file not found in $PATH: unknown
OCI运行时执行失败：执行失败：无法启动容器进程：执行：“货物”：在$PATH中找不到可执行文件：未知
报错上来看是："cargo"：在$PATH中找不到可执行文件
