当我尝试创建 web 应用程序 symfony 6 项目时，“无法将要求解析为一组可安装的软件包”

Question

When I try to create a web app symfony 6 project, I have this error message:"Your requirements could not be resolved to an installable set of packages" and dependencies seems not to be installed (Lot of folders in my project are missing).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions. You can also try re-running composer require with an explicit version constraint, eg "composer require symfony/webapp-pack:*" to figure out if any version is installable, or "composer require symfony/webapp-pack:^2.1" if you know which you need.

Installation failed, reverting./composer.json and./composer.lock to their original content.

Answer 1

Finally, I resolved the problem. I had a conflict with an old version of php. So, I uninstall et reinstall PHP and it works fine.
