Ubuntu 20.04 安装 Composer 的避坑指南：PHP版本、OpenSSL与镜像适配 Composer 是 PHP 生态的核心包管理工具，其运行依赖于 PHP 解释器、扩展支持及安全网络协议等底层能力。理解 Composer 原理需从 PHP 版本兼容性、OpenSSL TLS 协议支持、CA 证书有效性等基础环境要素切入；技术价值在于实现自动化依赖解析、PSR-4 自动加载与脚本执行，支撑 Laravel、Symfony 等主流框架工程化落地；典型应用场景涵盖本地开发环境搭建、CI/CD 流水线集成及私有仓库协作。本文聚焦 Ubuntu 20.04 这一广泛使用的 LTS 系统，针对 PH 阅读详情

1. 安装php

PHP For Windows: Binaries and sources Releases

我选的是8.2 点击ZIP下载

1.1. 配置php.ini

一开始只有开发和生产版本，php.ini需要自己手动改名

1.1.1. 开启openssl

1.1.2. 开启exenslon_dir="ext"

2. 安装composer

3. 配置环境变量

3.1. php:

3.2. composer

4. 测试项目安装

4.1. 项目安装：

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires phpunit/phpunit ^10.5.16 -> satisfiable by phpunit/phpunit[10.5.16, ..., 10.5.20].
- phpunit/phpunit[10.5.16, ..., 10.5.20] require ext-mbstring * -> it is missing from your system. Install or enable PHP's mbstring extension.
Problem 2
- codeigniter4/framework[4.0.0, ..., v4.2.10] require ext-curl * -> it is missing from your system. Install or enable PHP's curl extension.
- codeigniter4/framework[v4.2.11, ..., v4.5.1] require ext-intl * -> it is missing from your system. Install or enable PHP's intl extension.
- Root composer.json requires codeigniter4/framework ^4.0 -> satisfiable by codeigniter4/framework[4.0.0, ..., v4.5.1].

To enable extensions, verify that they are enabled in your .ini files:
- D:\phpstudy_pro\Extensions\php\php.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-mbstring --ignore-platform-req=ext-curl --ignore-platform-req=ext-intl` to temporarily ignore these required extensions.

简而言之就是缺少了一些依赖，去到php.ini开启即可
