我已经尝试了 Laravel 文档中的第一个命令
composer global 需要 laravel/安装程序
我有错误
Changed current directory to /Users/bheng/.composer
Using version ^2.0 for laravel/installer
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

我正在尝试创建一个新的 Laravel 项目。
最佳答案
您很可能需要 --update-with-all-dependencies 开关:
composer global require laravel/installer --update-with-all-dependencies
如果需要升级已安装的依赖项，Composer 拒绝升级包 -
--update-with-all-dependencies 用于更改此行为并升级所有必要的依赖项。关于php - composer global 需要 laravel/installer，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/55128100/
