使用未定义的常量JSON_INVALID_UTF8_SUBSTITUTE-假定为'JSON_INVALID_UTF8_SUBSTITUTE' [英] Use of undefined constant JSON_INVALID_UTF8_SUBSTITUTE - assumed 'JSON_INVALID_UTF8_SUBSTITUTE'

问题描述

我最近克隆了一个laravel项目，并在运行composer安装后出现此错误

I recently cloned a laravel project and after running composer install, I am getting this error

In LogManager.php line 416:

Use of undefined constant JSON_INVALID_UTF8_SUBSTITUTE - assumed 'JSON_INVALID_UTF8_SUBSTITUTE' 

我已经在网上检查了解决方案，但是找不到任何相关的解决方案.有什么帮助吗?

I have checked the web for solutions but can't find any related. Any assistance, please?

此外，如何找到LogManager.php?当我使用VSCode搜索时，它似乎不可用

Also, how can I find the LogManager.php? It doesn't seem to be available when I search with VSCode

推荐答案

您应该将php版本升级到7.2+.如果这不可能，这是我使用的修复程序.只需将其添加到您的index.php文件中即可:

You should upgrade your php version to 7.2+. If that is not possible, here is a fix that i used. Just add this to your index.php file:

if (!defined('JSON_INVALID_UTF8_SUBSTITUTE')) {
    //PHP < 7.2 Define it as 0 so it does nothing
    define('JSON_INVALID_UTF8_SUBSTITUTE', 0);
}
