macOS Docker 25.1 构建镜像时不在输出 echo 等命令输出的调试信息？

Question

Docker 的版本信息：??

构建日志：

Dockerfile 内容

FROM nginx
ARG TSET="test0001"
RUN echo "xxxx$TSET"
RUN echo  '你好' > text.txt && cat text.txt
RUN /bin/bash -c echo 'echo hello of dockerfile'
WORKDIR /app
RUN echo 'workdir after:' && pwd
#COPY /dist ./
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

Centos 下 Docker 构建的日志是可以正常显示：

Centos 下的 Docker version

这本身和docker没啥关系呀,你本身写法就有问题，

/bin/bash -c echo 'echo hello of dockerfile'

/bin/bash -c "cmd string"`中间多了一个echo
