Perhaps you should add the directory containing libpcre.pc to the PKG_CONFIG_PATH

錯誤如下：

checking for libpcre >= 7.8... Package libpcre was not found in the pkg-config search path. Perhaps you should add the directory containing `libpcre.pc' to the PKG_CONFIG_PATH environment variable No package 'libpcre' found
configure: error: Library requirements (libpcre >= 7.8) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.

• 配置PKG_CONFIG_PATH
• 改名

經過前面的操作，怎麼還有錯？

到lib/pkgconfig下，發現有一個libpcre2-8.pc，這是因為你使用了pcre2。下載下傳編譯pcre即可。
