Question

Using version ^3.1 for maatwebsite/excel
./composer.json has been updated
Running composer update maatwebsite/excel
Loading composer repositories with package information
Updating dependencies

您的要求无法解决为一组可安装的软件包。 问题 1

    - maatwebsite/excel[3.1.27, ..., 3.2.x-dev] require phpoffice/phpspreadsheet ^1.16 -> satisfiable by phpoffice/phpspreadsheet[1.16.0, 1.17.0, 1.17.1].
    - maatwebsite/excel 3.1.26 requires phpoffice/phpspreadsheet ^1.15 -> satisfiable by phpoffice/phpspreadsheet[1.15.0, 1.16.0, 1.17.0, 1.17.1].
    - maatwebsite/excel[3.1.28, ..., 3.1.x-dev] require phpoffice/phpspreadsheet 1.16.* -> satisfiable by phpoffice/phpspreadsheet[1.16.0].
    - maatwebsite/excel[3.1.0, ..., 3.1.25] require php ^7.0 -> your php version (8.0.5) does not satisfy that requirement.
    - phpoffice/phpspreadsheet[1.15.0, ..., 1.17.1] require ext-gd * -> it is missing from your system. Install or enable PHP's gd extension.
    - Root composer.json requires maatwebsite/excel ^3.1 -> satisfiable by maatwebsite/excel[3.1.0, ..., 3.2.x-dev].

To enable extensions, verify that they are enabled in your .ini files:
    - C:\xampp\php\php.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 and ./composer.lock to their original content.

Answer 1

您需要在php.ini文件中启用gd扩展。

那里有一行可能看起来像这样： ;extension=gd2 （或;extension=gd ），它需要是extension=gd2 （或extension=gd ）。

Answer 2

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. 大多数扩展都是默认安装和启用的。

您可以在 Ubuntu 中运行以下命令以确保已安装扩展。

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP 版本特定安装（如果安装了 PHP 7.4）

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring
