推荐答案
这是一个已知的 PHP 7.3 bug，已经修复了.
This is a known PHP 7.3 bug, which has already been fixed.
作为临时解决方法，编辑您的 php.ini 文件(在我的情况下:vi/usr/local/etc/php/7.3/php.ini)，通过更改禁用 PHP PCRE JIT 编译:
As a temporary workaround, edit your php.ini file (in my case: vi /usr/local/etc/php/7.3/php.ini), disable PHP PCRE JIT compilation by changing:
;pcre.jit=1
到
pcre.jit=0
