通过 composer 安装 package

Question

it gives me an error. my current dbal version is ^3.0

Problem 1 - lotuashvili/laravel-tbcpay[1.1.0, ..., 1.1.4] require doctrine/dbal ^2.9 -> found doctrine/dbal[v2.9.0, ..., 2.13.x-dev] but it conflicts with your root composer.json require (^3.0). - Root composer.json requires lotuashvili/laravel-tbcpay ^1.1 -> satisfiable by lotuashvili/laravel-tbcpay[1.1.0, ..., 1.1.4].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

I tried to update all packages

Answer 1

You're simply using incompatible package versions. lotuashvili/laravel-tbcpay package requires doctrine/dbal 2.9 and up (excluding 3.x), while you require doctrine/dbal 3.x.

Since there is no version of lotuashvili/laravel-tbcpay that supports doctrine/dbal 3.x, your only course of action is to downgrade Doctrine DBAL in your project to 2.9.

Answer 2

lotuashvili/laravel-tbcpay requires doctrine/dbal v2, your own composer.json requires that same package in v3. If you want to use lotuashvili/laravel-tbcpay (which hasn't seen any new package since nearly two years,), you should either downgrade DBAL or open a support ticket in their issue tracker
