CI4 入门问题

Question

决定试试新发布的 CI4。

Ubuntu 操作系统 php 7.4.3.

遵循 https://codeigniter4.github.io/userguide/installation/index.html

中的文档

composer create-project codeigniter4/appstarter c400
cd c400
# Not sure if this is needed
php builds development
composer update # per the build's output
php spark serve

这导致：

该错误与 Symfony 在首次引入预加载时生成的一些错误没有什么不同。但是 7.4.3 至少为 Symfony 解决了这些问题。

我开始逐步研究 spark 控制台代码，但我想看看是否还有其他人运行参与其中。

更新：来自https://forum.codeigniter.com/thread-75587.html，看来这个问题正在解决中。修复发布后我会回来关闭它。

等了几天才发布修复程序。是否进行了作曲家更新，将我从 CLI 4.0.1 转移到 4.0.2，但问题仍然存在。

创建了一个新项目，一切都按预期进行。

不确定作曲家更新是否应该工作，但至少现在显示了欢迎页面。
