Composer 安装时提示找不到 PHP.INI

如果没有一定得使用 centos 的原因，推荐使用 Ubuntu + 这个构建脚本 分享：Ubuntu 14/16 下的 Laravel LNMP 线上环境自动部署脚本

which php 
php -i |grep ini

@motecshine

[root@hualxxxyii ~]# which php
/usr/local/bin/php

[root@hualxxxyii ~]# php -i |grep ini

这有什么用

php --ini

终端输入这个命令 会打印ini文件的路径，如果发现没有这个文件的话，去拷贝一个默认的ini、文件到指定目录

Configuration File (php.ini) Path => /usr/local/lib
这去哪个文件改路径.

2.3.4.5 为什么报错，22行不是提示已经安装好了吗，8.9行不用管它吗？

8,9 行是说 /usr/local/lib 目录下找不到 php.ini文件，你去找一个你php对应版本的 默认ini文件 放到这个/usr/local/lib目录下

@zhaohehe
已经放了，重启动系统，执行PHP --INI 8.9行还是一样的显示

@vipta295844 编译安装的话 需要将 php-src/php.ini.development 放到指定的目录下
