【问题描述】：

我已经有 Composer 版本 @ package_branch_alias_version @ (1.0.0-beta2) 和 Laravel Installer 2.1.0。但是当我想做一个 laravel 项目时，它会显示如下错误：

Problem 1
    - Installation request for phpdocumentor/reflection-docblock 5.1.0 -> satisfiable by phpdocumentor/reflection-docblock[5.1.0].
    - phpdocumentor/reflection-docblock 5.1.0 requires ext-filter ^7.1 -> the requested PHP extension filter has the wrong version (7.2.23-1+ubuntu16.04.1+deb.sury.org+1) installed.
  Problem 2
    - phpdocumentor/reflection-docblock 5.1.0 requires ext-filter ^7.1 -> the requested PHP extension filter has the wrong version (7.2.23-1+ubuntu16.04.1+deb.sury.org+1) installed.
    - phpspec/prophecy v1.10.3 requires phpdocumentor/reflection-docblock ^2.0|^3.0.2|^4.0|^5.0 -> satisfiable by phpdocumentor/reflection-docblock[5.1.0].
    - Installation request for phpspec/prophecy v1.10.3 -> satisfiable by phpspec/prophecy[v1.10.3].

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/7.2/cli/php.ini
    - /etc/php/7.2/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.2/cli/conf.d/10-opcache.ini

    - /etc/php/7.2/cli/conf.d/20-xsl.ini
    - /etc/php/7.2/cli/conf.d/20-zip.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

我该怎么办？我在互联网上搜索了解决方案，但没有找到相同的解决方案。

【问题讨论】：

解决了，伙计们。我卸载了 composer 1.0.0 并安装了 composer 1.10.0

【参考方案1】：

如果您想使用这些软件包，请使用 PHP 7.1。请记住，您至少应该升级到 php 7.3。

【参考方案2】：

根据phpdocumentor 文档。它至少需要PHP 7.2。要解决这个问题upgrade your PHP version 或downgrade phpdocumentor package

requires

php: ^7.2
phpdocumentor/type-resolver: ^1.0
webmozart/assert: ^1
phpdocumentor/reflection-common: ^2.0
ext-filter: ^7.1

@Stev 尝试使用PHP 7.1
