configure: error: cannot run /bin/bash config/config.sub

linux下./configure 后可能会出现各种问题，缺少依赖包，或者版本 变量不一致等。不同的行为可能会产生同一错误，我是在安装 joy 工具时，遇到该报错。下面的方法不一定对你的问题一定有用，这就是个尝试的过程，只要能解决问题就好。
若你也是在安装 joy，可参考文章
操作环境：Ubuntu 16.04

问题描述

root@ubuntu:/home/joy# ./configure --enable-gzip
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
/home/joy/config/missing: line 3: $'\r': command not found
......
checking for ranlib... ranlib
configure: error: cannot run /bin/bash config/config.sub

确保已经安装下列工具

    yum install libtool       
    yum install libtool-ltdl    
    yum install libtool-ltdl-devel

在终端运行如下命令，查看报错处

root@ubuntu:/home/joy# /bin/bash config/config.sub
config/config.sub: line 4: $'\r': command not found
config/config.sub: line 6: $'\r': command not found
config/config.sub: line 26: $'\r': command not found
config/config.sub: line 27: $'\r': command not found
config/config.sub: line 34: $'\r': command not found
config/config.sub: line 37: $'\r': command not found
config/config.sub: line 45: $'\r': command not found
config/config.sub: line 52: $'\r': command not found
config/config.sub: line 54: $'\r': command not found
config/config.sub: line 67: $'\r': command not found
config/config.sub: line 75: $'\r': command not found
config/config.sub: line 78: $'\r': command not found
config/config.sub: line 81: syntax error near unexpected token `$'in\r'
config/config.sub: line 81: `  case $1 in

找道系统中所有的 config.sub 文件，与自己目录下的进行比较

root@ubuntu:~# find / -name config.sub
/home/joy/config/config.sub
/usr/share/libtool/build-aux/config.sub
/usr/share/misc/config.sub
/mnt/hgfs/CDH-Hadoop/joy/config/config.sub

错误解决
用系统中的config.sub 文件替换

mv /home/joy/config/config.sub /home/joy/config/config.sub.bak
cp /usr/share/libtool/build-aux/config.sub /home/joy/config/config.sub

mv /home/joy/config/config.guess /home/joy/config/config.guess.bak
cp /usr/share/libtool/build-aux/config.guess /home/joy/config/config.guess

进行测试 报错消除

root@ubuntu:/home/joy# ./configure --enable-gzip
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
/home/joy/config/missing: line 3: $'\r': command not found
/home/joy/config/missing: line 5: $'\r': command not found
......
checking for zlib.h... yes
checking for zlib.h... (cached) yes
