　　下载地址：https://github.com/transcode-open/apt-cyg
　　二、将文件放入/usr/local/binAdministrator@jwj /usr/local/bin $ ls -l total 16 -rw-r--r-- 1 Administrators None 13765 Jan 29  2017 apt-cyg
　　三、追加执行权限Administrator@jwj /usr/local/bin $ chmod +x ./apt-cyg  Administrator@jwj /usr/local/bin $ ls -l total 16 -rwxr-xr-x 1 Administrators None 13765 Jan 29  2017 apt-cyg
　　四、将/usr/local/bin加入环境变量
　　通过操作系统的环境变量里加入
　　或修改/home/Administrator/.profile或.bashrc , 追加export PATH=$PATH:/usr/local/bin# a patch to the cygwin mailing list.  # User dependent .profile file  # Set user-defined locale export LANG=$(locale -uU) export PATH=$PATH:/usr/local/bin  # This file is not read by bash(1) if ~/.bash_profile or ~/.bash_login # exists. # # if running bash if [ -n ＂${BASH_VERSION}＂ ]; then   if [ -f ＂${HOME}/.bashrc＂ ]; then     source ＂${HOME}/.bashrc＂   fi fiAdministrator@jwj ~ $ echo $PATH /usr/local/bin:/usr/bin:/cygdrive/c/Python36/Scripts:/cygdrive/c/Program Files (x86)/Common Files/Oracle/Java/javapath:/cygdrive/c/Windows/system32
　　五、使用
　　设置下载源：Administrator@jwj ~ $ apt-cyg mirror https://mirrors.aliyun.com/cygwin Mirror set to https://mirrors.aliyun.com/cygwin.
　　安装busybox:Administrator@jwj ~ $ apt-cyg install busybox --2022-03-27 10:17:16--  https://mirrors.aliyun.com/cygwin/x86_64/setup.bz2 Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 36.158.239.228, 36.158.239.224, 36.158.239.230, ...
