无法在我的流明中安装照明/通知

Question

I'm having an error to install this package composer require illuminate/notifications to my Lumen 5.3.3 . I also tried to update my PHP.

Is there something that I need to add or change?

$ composer require illuminate/notifications
Using version ^5.4 for illuminate/notifications
./composer.json has been updated

    - Can only install one of: illuminate/mail[5.4.x-dev, v5.3.23].
    - Can only install one of: illuminate/mail[5.5.x-dev, v5.3.23].
    - Installation request for illuminate/mail (locked at v5.3.23, required as 5.3.*) -> satisfiable by illuminate/mail[v5.3.23].

Installation failed, reverting ./composer.json to its original content.

Here is my composer.json :

I also tried to intall the packages for lumen 5.3 but still it gives me this error

Answer 1

It seems you still have Lumen 5.3 installed but you want to install illuminate/notifications in version 5.4 which requires also Lumen to be version 5.4 .

I would do:

• Upgrade Lumen to 5.4 by setting "laravel/lumen-framework": "5.4.*", in your composer.json
• After that do a composer update
• Then install composer require illuminate/notifications

OR:

• composer require illuminate/notifications:~5.3 .. which installs the package for Lumen 5.3

should work as well.

Answer 2

illuminate/notifications:^5.4 needs illuminate/mail:5.4.* . You project is using illuminate/mail:5.3.* (from your composer.json file). So to install illuminate/notifications:^5.4 , you need to upgrade your illuminate/mail . Do this:

composer require "illuminate/mail:^5.4"

After that

composer require "illuminate/notifications:^5.4"
