尝试从作曲家安装laravel时缺少PHP扩展名zip

Question

我在这里的其他帖子上看到了这个问题的答案，但是所有答案都对我无效。主要是因为我试图在Mac上本地安装laravel，答案是针对Linux环境的，而且brew声称它没有此扩展。这是我运行composer命令时的输出：

$ composer global require "laravel/installer"

Changed current directory to /Users/frankaddelia/.composer
Using version ^2.0 for laravel/installer
./composer.json has been updated
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
    - laravel/installer v2.0.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - laravel/installer v2.0.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - Installation request for laravel/installer ^2.0 -> satisfiable by laravel/installer[v2.0.0, v2.0.1].

  To enable extensions, verify that they are enabled in your .ini files:
    - /usr/local/php5/lib/php.ini
    - /usr/local/php5/php.d/10-extension_dir.ini
    - /usr/local/php5/php.d/20-extension-opcache.ini
    - /usr/local/php5/php.d/40-curl.ini
    - /usr/local/php5/php.d/40-openssl.ini
    - /usr/local/php5/php.d/50-extension-apcu.ini
    - /usr/local/php5/php.d/50-extension-curl.ini
    - /usr/local/php5/php.d/50-extension-gmp.ini
    - /usr/local/php5/php.d/50-extension-igbinary.ini
    - /usr/local/php5/php.d/50-extension-imap.ini
    - /usr/local/php5/php.d/50-extension-intl.ini
    - /usr/local/php5/php.d/50-extension-mcrypt.ini
    - /usr/local/php5/php.d/50-extension-mongodb.ini
    - /usr/local/php5/php.d/50-extension-mssql.ini
    - /usr/local/php5/php.d/50-extension-pdo_pgsql.ini
    - /usr/local/php5/php.d/50-extension-pgsql.ini
    - /usr/local/php5/php.d/50-extension-propro.ini
    - /usr/local/php5/php.d/50-extension-raphf.ini
    - /usr/local/php5/php.d/50-extension-readline.ini
    - /usr/local/php5/php.d/50-extension-redis.ini
    - /usr/local/php5/php.d/50-extension-xsl.ini
    - /usr/local/php5/php.d/99-liip-developer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

我尝试用brew安装缺少的扩展名，但出现如下错误：

$ brew install php7.2-zip
Updating Homebrew...
Error: No available formula with the name "php7.2-zip" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

顺便说一下，这是我的PHP版本：

php -v
PHP 7.3.0beta2 (cli) (built: Aug 21 2018 08:13:27) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.0-dev, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.3.0beta2, Copyright (c) 1999-2018, by Zend Technologies

我似乎无法弄清楚如何获得此缺少的扩展名，并且经过数小时的谷歌搜索后，仍未找到适合我的解决方案。我只是重新格式化了Mac，以处理另一个服务器环境问题，所以我不介意重新安装并重新开始，但是我想尝试解决此问题，如果可能的话，不要这样做。非常感谢您的帮助！

Answer 1

在终端上运行：sudo apt-get install php7.2-zip && sudo apt-get install php-zip。之后，您将运行命令（sudo作曲家全局需要“ laravel / installer”）

Answer 2

为什么作曲家错误显示您正在使用php5？

您之前使用过php5吗？如果是，我想您可以先尝试卸载php5

首先，您必须安装php扩展zip。要安装，只需运行以下

    sudo apt-get install php7.2-zip && sudo apt-get install php-zip

现在您可以尝试再次使用composer安装laravel安装程序
