安装oniguruma报错
[root@Stable oniguruma-6.9.4]# ./autogen.sh && ./configure --prefix=/usr/local/oniguruma6
Generating autotools files.
Can‘t exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 326.
autoreconf: failed to run aclocal: No such file or director
网上搜了一下，中文答案多不靠谱，英文还好，有一篇可以解决：
`aclocal‘ is part of automake package, try to install it first.
所以，下载了automake之后，编译、安装，在执行就正常了
yum install automake #安装它解决
