尝试在xampp服务器上安装socialigniter，它是codeigniter社交网络项目。但是当我开始安装并打开 localhost/socialigniter/install.php 时出现此错误？我不知道这是什么错误，只是页面上的这段文字
{"status":"success","message":"Created files & folders","data":{"base_url":"","hostname":"","username":"","password":"","database":""}}
这是一个install.php页面源

最佳答案
确认我刚刚解决了这个问题，并遇到了多个错误，包括你得到的错误。其他评论者不正确，它应该进入安装的下一步。
这个项目的 github 上有一个线程，有人尝试安装，但遇到错误 - 原始开发人员说他全职从事另一个项目，无法维护它。
这个项目中显然有一些很棒的东西，所以如果您调试安装，请再次发布。
