推荐答案

有一个关于为 pcre 重建 RPM 的很好的教程 这里.

There's a good tutorial on rebuilding the RPM for pcre here.

如果您向下滚动到更新的 RPM 文件...",您会发现一些预先构建的 RPM,如果您只是想让它工作(记住在完成后重新启动 Apache,而不仅仅是正常的重新加载).

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--enable-unicode-properties

The tl;dr version is: recompile pcre with --enable-utf8 and --enable-unicode-properties
