laravel/cashier v7.0.5 需要 stripe/stripe-php ~4.0 -> 可以满足 stripe/stripe-php

Question

我有一个 Laravel 5.5 项目并尝试从我的终端运行此命令

composer require laravel/cashier

但我遇到了这个问题：

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.1/cli/php.ini
    - /etc/php/7.1/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.1/cli/conf.d/10-opcache.ini
    - /etc/php/7.1/cli/conf.d/10-pdo.ini
    - /etc/php/7.1/cli/conf.d/15-xml.ini
    - /etc/php/7.1/cli/conf.d/20-calendar.ini
    - /etc/php/7.1/cli/conf.d/20-ctype.ini
    - /etc/php/7.1/cli/conf.d/20-dom.ini
    - /etc/php/7.1/cli/conf.d/20-exif.ini
    - /etc/php/7.1/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.1/cli/conf.d/20-ftp.ini
    - /etc/php/7.1/cli/conf.d/20-gettext.ini
    - /etc/php/7.1/cli/conf.d/20-iconv.ini
    - /etc/php/7.1/cli/conf.d/20-json.ini
    - /etc/php/7.1/cli/conf.d/20-mbstring.ini
    - /etc/php/7.1/cli/conf.d/20-mcrypt.ini
    - /etc/php/7.1/cli/conf.d/20-mysqli.ini
    - /etc/php/7.1/cli/conf.d/20-pdo_mysql.ini
    - /etc/php/7.1/cli/conf.d/20-phar.ini
    - /etc/php/7.1/cli/conf.d/20-posix.ini
    - /etc/php/7.1/cli/conf.d/20-readline.ini
    - /etc/php/7.1/cli/conf.d/20-shmop.ini
    - /etc/php/7.1/cli/conf.d/20-simplexml.ini
    - /etc/php/7.1/cli/conf.d/20-sockets.ini
    - /etc/php/7.1/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.1/cli/conf.d/20-sysvsem.ini

    - /etc/php/7.1/cli/conf.d/20-xmlreader.ini
    - /etc/php/7.1/cli/conf.d/20-xmlwriter.ini
    - /etc/php/7.1/cli/conf.d/20-xsl.ini
    - /etc/php/7.1/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.

根据我所做的谷歌研究，我尝试将sudo apt-get install php-curl 作为一种可能的解决方案，但对我不起作用。

有人知道我该如何解决这个问题吗？

编辑这是我的 composer.json 文件

Answer 1

由于错误消息建议您在 PHP 上安装 curl 扩展。请安装 curl 并重新启动您的网络服务器。

您需要确保为您的 PHP 安装正确版本的 curl 扩展。 在你的情况下：

sudo apt-get install php7.1-curl

列出你的 php 上加载的扩展/模块
在终端上运行以下命令

$ php -m

Answer 2

尝试运行composer require "laravel/cashier":"7.0" 而不仅仅是composer require laravel/cashier。 Laravel 已更新到 5.6，所以你拉错了 5.5 的版本
