upgrade升级nginx时候报错！！
如题，我是老版本的nignx想升级到1.18.0版本，外加ssl_preread_module扩展。前两台机器没有问题，最后一台机器以前留的lnmp文件夹删掉了。我从新下载了个版本打算执行upgrade升级一下nignx，结果报错127。日志我传到附件里，不是很大。
前两台我升级nginx是以前安装lnmp没有删掉，用文件夹里的upgrade直接升级。最后一台机器是删掉了。我又从新下了个1.9的升级nginx失败，下了个1.6的也是同样的失败。

你用的什么系统及版本？
是否修改了编译参数或lnmp.conf，修改了哪些参数？
系统上的pcre版本是否自行升级过？
