当我用Dockle检查我的坞站图像时，我收到一个致命错误：

和,
这是我的文档文件：

FROM nginx:latest

WORKDIR /

RUN apt-get update && apt-get install -y 
    gcc 
    libfcgi-dev 
    spawn-fcgi 
    && apt-get clean 
    && rm -rf /var/lib/apt/lists/*

RUN chmod 777 /var/cache/nginx/ /var/run/

COPY server/nginx/nginx.conf /etc/nginx/
COPY server/hello.c /etc/nginx/
COPY server/span-fcgi.sh /etc/nginx/

RUN chmod +x /etc/nginx/span-fcgi.sh 
    && gcc -o /etc/nginx/hello.fcgi /etc/nginx/hello.c -lpthread -lfcgi 
    && usermod -aG root,gnats,daemon,disk,sudo nginx

EXPOSE 81

USER nginx

CMD ["/etc/nginx/span-fcgi.sh"]

脚本“span-fcgi.sh”包含

# !/bin/bash

spawn-fcgi -a 127.0.0.1 -p 8080 -f /etc/nginx/hello.fcgi -F 1  
nginx -g 'daemon off;

请告诉我的Docker文件中发生了什么，使Dockle在上面显示错误？如何解决问题并让Dockle闭嘴？
