使用 composer 安装 MixPHP 遇到提示 PHP 缺少扩展很诡异

This topic created in 2385 days ago, the information mentioned may be changed or developed.

Do not run Composer as root/super user! See https://getcomposer.org/root for details Installing mix/mix (v2.0.7) - Installing mix/mix (v2.0.7): Loading from cache Created project in /home/wwwroot/mix Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested PHP extension ext-redis * is missing from your system. Install or enable PHP's redis extension. Problem 2 - The requested PHP extension ext-mbstring * is missing from your system. Install or enable PHP's mbstring extension.

但是我本地输出 phpinfo() 跟 执行 php -m 都有这两个扩展 我也本地测试 redis $redis = new Redis() or die("Cannot load Redis module."); $redis->connect('localhost',6379); $auth = $redis->auth('redis');//redis 改为你的 redis 密码 $redis->set('name', '111'); echo $redis->get('name'); 结果是输出 111

求各位大佬支个招

@emeab composer 使用的是“环境变量”里面的 php php -v 跟我 phpinfo 输出出来的 php 是一个版本的

php composer.phar install 试试，仔细检查下 composer 运行的到底是那个 php，加载的是哪个 php.ini 。

@haiyang416 执行 php composer.phar install 报错 Could not open input file: composer.phar
问下怎么检查 composer 运行的到底是那个 php，加载的是哪个 php.ini 步骤要怎么去实现

首先确认 composer 的 php 和你直接执行的 php 是不是同一个
`which composer` 找到对应的 composer 执行文件，打开看看第一行类似这样的 `#!/usr/bin/env php`
执行第一行里的 `/usr/bin/env php -v (-m)` 看看和`php -v (-m)`的一样不

或者执行 `composer show -p` 看看

@littleylv 查出来确实 php 跟 php -v 的不一样那要怎么去切换 composer 的 php 版本呢

@q569321245 #6 那简单，就是跟 @haiyang416 #3 说的一样，指定 php

/path/to/php /path/to/composer install xxx

/usr/bin/php /usr/local/bin/composer show -p 比如我这样执行的就是 macOS 自带的 php7.3.8
/usr/local/bin/php /usr/local/bin/composer show -p （或者不指定路径就是默认的 php /usr/local/bin/composer show -p 或者 composer show -p ）就是执行 brew 安装的 php7.3.11

@littleylv 我刚才试下了 /path/to/php(有 redis.mbstring 扩展的 php) composer create-project mix/mix --prefer-dist 还是会报错

Could not open input file: composer 吗？
那肯定的呀，你这个时候执行的是 php，后面得跟 php 文件，所以需要 /path/to/composer 而不是 composer
具体 composer 路径 `which composer`

/path/to/php /path/to/composer install xxx

@littleylv 不是是报缺少扩展
