今天克隆代码之后，在composer install 的时候出现了一些问题，在此记录一下。
错误代码如下：
[root@localhost MarketingCenter]# composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for php-amqplib/php-amqplib v2.7.0 -> satisfiable by php-amqplib/php-amqplib[v2.7.0].
- php-amqplib/php-amqplib v2.7.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
Problem 2
- php-amqplib/php-amqplib v2.7.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
- php-amqplib/thumper v0.5.0 requires php-amqplib/php-amqplib ^2.6 -> satisfiable by php-amqplib/php-amqplib[v2.7.0].
- Installation request for php-amqplib/thumper v0.5.0 -> satisfiable by php-amqplib/thumper[v0.5.0].
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php.ini
- /etc/php.d/curl.ini
- /etc/php.d/fileinfo.ini
- /etc/php.d/json.ini
- /etc/php.d/phar.ini
- /etc/php.d/zip.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
由此可见 要给php 增加扩展 ext-bcmath
1、进入如下目录
cd /usr/local/php/lib
2、然后执行如下代码
yum install php-bcmath
即可安装成功，
由上图问题还需要继续安装mbstring
yum install php-mbstring
回车即可安装成功，
最后解决了问题，在继续composer install，好了操作完成！
