查看composer版本時，報錯如下
[root@iZm5eajbhqhhehk85j4d95Z ~]# composer --version
PHP Warning: PHP Startup: Unable to load dynamic library 'curl' (tried: /www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/curl (/www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/curl: cannot open shared object file: No such file or directory), /www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/curl.so (/www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/curl.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
PHP警告：PHP啟動：無法加載動態庫’curl’
然后，我百度了橙色標記的部分，查出解決方法
這是擴展重復加載，打開php.ini文件，然后將 extension = curl，注釋掉，也就是前面加上分號 “;”，之后重啟php-fpm即可
