尝试从 Composer 安装 Laravel 时缺少 PHP 扩展 zip

Missing PHP extension zip when trying to install laravel from composer

提问by Frank A.

I have seen this question answered on other posts here, but none of the answers work for me. Mostly because I'm trying to install laravel locally on my mac and the answers are for Linux environments and brew claims it doesn't have this extension. Here is my output when I run the composer command:

我在这里的其他帖子中看到了这个问题的回答，但没有一个答案对我有用。主要是因为我试图在我的 mac 上本地安装 laravel，而答案是针对 Linux 环境的，而 brew 声称它没有这个扩展。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.

I try to install the missing extension with brew, but I get this error like so:

我尝试用 brew 安装缺少的扩展，但我收到这样的错误：

$ 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.

By the way, here is my php version:

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 )

    with Zend OPcache v7.3.0beta2, Copyright (c) 1999-2018, by Zend Technologies

I can't seem to figure out how to get this missing extension and haven't found a solution that works for me after a few hours of googling. I just reformatted my mac dealing with a different server environment issue, so I don't mind reinstalling again and starting over, but I want to try to fix the issue without doing so if possible. Any help is greatly appreciated!

我似乎无法弄清楚如何获得这个缺少的扩展，并且在谷歌搜索了几个小时后还没有找到适合我的解决方案。我刚刚重新格式化了我的 mac 以处理不同的服务器环境问题，所以我不介意再次重新安装并重新开始，但如果可能的话，我想尝试解决问题而不这样做。任何帮助是极大的赞赏！

Run this on terminal: sudo apt-get install php7.2-zip && sudo apt-get install php-zip. After which you would run the command (sudo composer global require "laravel/installer")

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 composer global require "laravel/installer"）

Why the composer error show that you are using php5?

Are you using php5 before ? If yes I think you can try uninstall the php5 first

你以前用过php5吗？如果是，我想您可以先尝试卸载 php5
