PCRE库缺失问题

问题

在阿里云Ubuntu 26.04自编译安装Nginx遇到PCRE库缺失

报错如下：

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

解决方法

下载最新PCRE包：https://github.com/PCRE2Project/pcre2/releases
解压进入目录

1 2	tar zxvf pcre2-x.xx.tar.gz cd pcre2-x.xx

编译安装

./configure
make
make install

更新动态链接器缓存

ldconfig

Q&A

为什么不用 apt-get install libpcre3-dev?

因为会遇到报错：

1	Package libpcre3-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source.
