当我尝试使用命令行安装时：
composer self-update && composer create-project --prefer-dist cakephp/app my_app_name
我不断收到这条消息，我以前没有，现在哪一个是必需的，哪一个不是，我每次都必须手动下载吗？
cakephp/app suggests installing markstory/asset_compress (An asset compression plugin which provides file concatenation and a flexible filter system for preprocessing and minification.)
cakephp/app suggests installing dereuromark/cakephp-ide-helper (After baking your code, this keeps your annotations in sync with the code evolving from there on for maximum IDE and PHPStan compatibility.)
cakephp/app suggests installing phpunit/phpunit (Allows automated tests to be run without system-wide install.)
cakephp/cakephp suggests installing lib-ICU (The intl PHP library, to use Text::transliterate() or Text::slug())

这些只是可以扩展已安装软件包功能的建议，但是没有它们，一切都应该可以正常工作。例如，monolog/monolog会建议几个插件，这些插件将允许登录到不同的后端。但是monolog/monolog没有它们就可以工作 - 例如，您可能无法登录到 Sentry，但如果没有此功能monolog仍然可以使用。
所以通常你可以忽略这些建议。但是你可以花几分钟时间检查这些建议的包的实际作用 - 你可以了解新技术和解决方案，这些技术和解决方案可以使你的应用更好、更易于维护。
如果你真的对这些建议不感兴趣，你可以使用--no-suggest开关来避免在install/update/require上显示它们：
composer install --no-suggest
