codeigniter - CI4 入门问题

Question

决定尝试一下新发布的 CI4。

Ubuntu 操作系统，php 7.4.3。

按照 https://codeigniter4.github.io/userguide/installation/index.html 上的文档进行操作

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

结果是:

CodeIgniter CLI Tool - Version 4.0.1 - Server-Time: 2020-02-24 10:41:36am

这个错误与 Symfony 在首次引入预加载时产生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，但我想我会看看是否有其他人遇到过这个问题。

更新:来自https://forum.codeigniter.com/thread-75587.html ，看来这个问题正在解决。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 Composer 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 Composer 更新是否应该起作用，但至少现在显示了欢迎页面。
