安装hiredis后swoole扩展消失

php -m报错：

PHP Warning: PHP Startup: Unable to load dynamic library 'swoole' (tried: /home/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/swoole (/home/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/swoole: cannot open shared object file: No such file or directory), /home/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so (libhiredis.so.0.13: cannot open shared object file: No such file or directory)) in Unknown on line 0

解决方案：

用vi打开当前用户的bash_profile

vi ~/.bash_profile
在最后一行添加：   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

最后再 source ~/.bash_profile
