Question

我有PHP版本：

php -v
PHP 7.1.9-1

作曲家版本：

Composer version 1.5.2 2017-09-11 16:59:25

现在我收到这个错误，我无法解决这个问题，因为我是这项技术的新手。

 composer global require "laravel/installer"
    Changed current directory to /home/indous-ubuntu/.composer
    Using version ^1.4 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 v1.4.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
        - laravel/installer v1.4.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
        - Installation request for laravel/installer ^1.4 -> satisfiable by laravel/installer[v1.4.0, v1.4.1].

      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

      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.

如果有人知道这个问题是什么，请帮我解决这个问题！

提前致谢！

Answer 1

编辑composer.json文件并替换为

"require": {
    "laravel/framework": "4.2.*",
    "laracasts/commander": "~1.0",
    "laracasts/validation": "~1.0",
    "laracasts/presenter": "0.1.*"
},
"require-dev": {
    "way/generators": "~2.0"
},

Answer 2

启用你的php ext-zip lib。用

安装 php版本7的

sudo apt-get install php7.0-zip

Answer 3

正如错误中已明确描述的那样，您缺少php-zip扩展名：

问题1 - laravel / installer v1.4.1需要ext-zip * - ＆gt;您系统中缺少所请求的PHP扩展zip。

尝试使用此命令安装它（使用sudo）：

apt-get install php-zip

它将自动为PHP7安装它作为Ubuntu存储库中PHP的默认版本。

PS：如果您已经安装了php-zip但仍然无效，请将扩展程序添加到php.ini中的/etc/php文件中，您就可以了。

在ubuntu
