[Bug]: Cannot install the package

[cool-energie]

Is the bug applicable and reproducable to the latest version of the package and hasn't it been reported before?

• Yes, it's still reproducable

What version of Laravel Excel are you using?

3.1

What version of Laravel are you using?

8.83.27

What version of PHP are you using?

7.4.33

Describe your issue

When i execute the command "composer require maatwebsite/excel:^3.1", I get this output:

==============

The "3.1" constraint for "maatwebsite/excel" appears too strict and will likely not match what you want. See https://getcomposer.org/constraints
./composer.json has been updated
Running composer update maatwebsite/excel
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires maatwebsite/excel 3.1 -> satisfiable by maatwebsite/excel[3.1.0].
- maatwebsite/excel 3.1.0 requires illuminate/support ^5.5 -> found illuminate/support[v5.5.0, ..., 5.8.x-dev] but these were not loaded, likely because it conflicts with another require.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

===============================

If i execute "composer require maatwebsite/excel" i get the 1.1 version and i want the 3.1 version.

How can the issue be reproduced?

I have only copy the command from the documentation and execute it in the console.

What should be the expected behaviour?

Installation command work without issues

Make sure you read the requirements in the docs. You are most likely missing a php extension that is required

@cool-energie Same issue here! Found any solutions?

[Dev-rahul]

same issue with me, let me know if you have found a fix @cool-energie

[cool-energie]

@sdon2 , @Dev-rahul I didn't found a fix yet sorry.

Found that v3.1 requires PHP 8.0. Its working fine with my PHP 8.2 environment flawlessly.

I installed successfully using composer require maatwebsite/excel:^3.1.55.

When running composer require maatwebsite/excel:^3.1, composer will first use v3.1.0 for dependency check, but v3.1.0 does not support PHP ^8.0, as shown below:

Laravel-Excel/composer.json

Line 23 in 968614f

"php": "^7.0",

Until v3.1.26, php ^8.0 was added to composer.json.

Laravel-Excel/composer.json

Line 24 in 66f7c95

"php": "^7.0|^8.0",

To sum up, if you want to install it on PHP 8.0 or above, please lock the version number to v3.1.26 or later.

我使用 安装成功composer require maatwebsite/excel:^3.1.55。

在运行时composer require maatwebsite/excel:^3.1，Composer会首先使用v3.1.0进行依赖检查，但是v3.1.0不支持PHP^8.0，如下所示：

Laravel-Excel/composer.json

Line 23 in 968614f

"php": "^7.0",

直到 v3.1.26，php ^8.0 才被添加到composer.json。

Laravel-Excel/composer.json

Line 24 in 66f7c95

"php": "^7.0|^8.0",

综上所述，如果要在PHP 8.0以上版本安装，请将版本号锁定为v3.1.26或更高版本。

This may require an update to the documentation.

i try to install maatwebsite/excel:^3.1.55 but i found that install first phpoffice/phpspreadsheet: ^2.1,.

i think that can update composer.json

"phpoffice/phpspreadsheet": "^1.15",
"phpoffice/phpspreadsheet": "^1.15|^2.0 ",

Changelog Phpspreadsheet

[patrickbrouwers]

Don't install 2.0 of phpspreadsheet before installing this package, it's not supported yet
