git: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

如果执行  git --version 的时候，提示

git: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

错误的话，解决办法如下：

1.在/etc/ld.so.conf中加一行/usr/local/lib

2.然后运行/sbin/ldconfig，文件解决，没有报错
