推薦答案
有一個關于為 pcre 重建 RPM 的很好的教程 這里.
There's a good tutorial on rebuilding the RPM for pcre here.
如果您向下滾動到更新的 RPM 文件..."，您會發現一些預先構建的 RPM，如果您只是想讓它工作(記住在完成后重新啟動 Apache，而不僅僅是正常的重新加載).
If you scroll down to "Updated RPM file for..." you'll find some pre-built RPM's if you just want it to work (remember to restart Apache after you're done, not just a graceful reload).
tl;dr 版本是:用 --enable-utf8 和 --enable-unicode-properties
The tl;dr version is: recompile pcre with --enable-utf8 and --enable-unicode-properties
