问题描述
我只是想知道作曲家在检查需求时如何检查要使用哪个php.我使用MacOS，并且在终端类型中:
I just wondering how composer check which php to use when check for requirements. I use MacOS and in terminal type:
composer require phpunit/phpunit
结果类似于:
Problem 1
- phpunit/phpunit 5.0.4 requires php >=5.6 -> your PHP version (5.5.27) or "config.platform.php" value does not satisfy that requirement....
当我检查php版本时:
When I check php version:
php -v
结果是:
哪个是:
which php
php:别名为/Applications/MAMP/bin/php/php5.6.10/bin/php
php: aliased to /Applications/MAMP/bin/php/php5.6.10/bin/php
有人可以解释这一点吗?预先感谢！
Can someone explain this. Thanks in advance!
推荐答案
如果指定调试详细信息-vvv，Composer可以告诉您正在运行的PHP版本.
Composer can tell you what version of PHP it's running on, if you specify debug verbosity -vvv.
我喜欢用about命令运行它，因为输出相对较短.
I like to run it with the about command, since the output is relatively short.
composer -vvv about
示例输出:
这引起了人们的兴趣，超出了我的预期，因此这是一个输出更干净的版本:
This has gotten more interest than I expected, so here's a version with cleaner output:
composer -vvv about 2>&1 | grep "PHP"
