無法安裝背包genreators.Laravel 7.10版

Question

我有一個新安裝的 Laravel 7.10。* 我想安裝 Backpack composer require backpack/generators --dev但無法安裝發電機。 這是錯誤。

Your requirements could not be resolved to an installable set of packages.

Problem 1 - Installation request for laravel/framework (locked at v7.10.3, required ^7.0) -> satisfiable by laravel/framework[v7.10.3]. - Installation request for backpack/generators ^3.0 -> satisfiable by backck/generators[3.0.0, v3.0.1, v3.x-dev]. - Can only install one of: backpack/crud[4.1.x-dev, 4.0.61]. - Can only install one of: backpack/crud[4.1.x-dev, 4.0.61]. - Can only install one of: backpack/crud[4.1.x-dev, 4.0.61]. - Conclusion: install backpack/crud 4.1.x-dev - Installation request for backpack/crud (locked at 4.0.61, required as 4.*) -> satisfiable by backpack/crud[4.0.61].

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

這是我的composer.json

Answer 1

問題是您將backpack/crud版本鎖定為4.0.* ，但對於backpack/generators而言，可滿足的版本是： 4.1.0, 4.1.1, 4.1.x-dev

因此，您應該在composer.json中更改此行：

"backpack/crud": "4.0.*",

對此：

"backpack/crud": "4.1.*",

然后更新作曲家包：

composer update

最后安裝發電機package：

composer require backpack/generators --dev
