Question

我正在尝试首次使用composer安装Laravel。

按照https://laravel.com/docs/5.1的文档进行操作之后，我尝试使用命令sudo composer global require "laravel/installer"进行操作。

我得到的输出粘贴在下面：

Changed current directory to /home/israel/.composer
Using version ^2.0 for laravel/installer
./composer.json has been created
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 those .ini files:
    - /etc/php/7.2/cli/php.ini
    - /etc/php/7.2/cli/conf.d/10-opcache.ini
    - /etc/php/7.2/cli/conf.d/10-pdo.ini
    - /etc/php/7.2/cli/conf.d/15-xml.ini
    - /etc/php/7.2/cli/conf.d/20-calendar.ini
    - /etc/php/7.2/cli/conf.d/20-ctype.ini
    - /etc/php/7.2/cli/conf.d/20-curl.ini
    - /etc/php/7.2/cli/conf.d/20-dom.ini
    - /etc/php/7.2/cli/conf.d/20-exif.ini
    - /etc/php/7.2/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.2/cli/conf.d/20-ftp.ini
    - /etc/php/7.2/cli/conf.d/20-gettext.ini

    - /etc/php/7.2/cli/conf.d/20-mbstring.ini
    - /etc/php/7.2/cli/conf.d/20-phar.ini
    - /etc/php/7.2/cli/conf.d/20-posix.ini
    - /etc/php/7.2/cli/conf.d/20-readline.ini
    - /etc/php/7.2/cli/conf.d/20-shmop.ini
    - /etc/php/7.2/cli/conf.d/20-simplexml.ini
    - /etc/php/7.2/cli/conf.d/20-sockets.ini
    - /etc/php/7.2/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.2/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.2/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.2/cli/conf.d/20-tokenizer.ini
    - /etc/php/7.2/cli/conf.d/20-wddx.ini
    - /etc/php/7.2/cli/conf.d/20-xmlreader.ini
    - /etc/php/7.2/cli/conf.d/20-xmlwriter.ini
    - /etc/php/7.2/cli/conf.d/20-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, deleting ./composer.json.

这是否意味着未安装PHP？

Answer 1

如果您尝试

sudo apt-get install php7.2-zip

，您遇到了错误：

sudo: apt-get: command not found

然后，尝试使用自制软件：

brew install php

这对我有用。希望它可以节省一些额外的时间，例如：祝您编程愉快！

Answer 2

看看Laravel的要求：

union all

你遇到他们吗？您的错误消息指出，您的环境不符合PHP版本和扩展名，因此您必须先安装它们。一旦安装了正确的PHP版本和相应的扩展，composer将能够根据需要安装laravel。

希望这会有所帮助！：）

Answer 3

只需运行sudo apt-get install php7.2-zip && sudo apt-get install php-zip。之后，您将再次运行命令（sudo composer global require "laravel/installer"）。

它应该可以正常工作。

它确实做到了。：）

Composer install Laravel：您的要求无法解决为一组可安装的软件包
