无法将 Jetstream package 安装到 Laravel 项目

Question

I use Laravel 8 framework. PHP version is 7.4. After running command

composer require laravel/jetstream

I have some errors:

To enable extensions, verify that they are enabled in your.ini files: - /etc/php/php.ini - /etc/php/conf.d/igbinary.ini - /etc/php/conf.d/redis.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 have read some manuals, but I didn't see similar errors. Please, help.

Answer 1

You need to enable the extension iconv from the file 'etc/php/ini.php' by uncommenting the line where extension= iconv , I'm not sure about the path of the file in Windows and Mac Os since I use Linux
