麻烦加上 export LUA_INCLUDE_DIR=$LUAJIT_INC 试试

xiaocang
echo $LUA_INCLUDE_DIR

/usr/local/LuaJIT/include/luajit-2.0

还是不行.

checking for LuaJIT 2.x ... not found
./configure: error: unsupported LuaJIT version; ngx_http_lua_module requires LuaJIT 2.x.

      LuaJIT 我是这样安装的,不知道有没有问题/

      cd LuaJIT-2.0.5
      make install PREFIX=/usr/local/LuaJIT

      /usr/local/LuaJIT$ ls
      bin include lib share

        #define LUAJIT_VERSION "LuaJIT 2.0.5"
        #define LUAJIT_VERSION_NUM 20005 /* Version 2.0.5 = 02.00.05. */
        #define LUAJIT_VERSION_SYM luaJIT_version_2_0_5

          我看到你用的 luajit2-2.1-20201027.tar.gz 这个源码包，但是 $LUA_INCLUDE_DIR 的输出结果是

          $ echo $LUA_INCLUDE_DIR
/usr/local/LuaJIT/include/luajit-2.0

          麻烦再确认下，你编译安装后的 luajit 的头文件在哪个目录

          xiaocang 这个我刚刚看issue的时候注意到了，发现路径错误了，是2.1（就如我最早echo的2.1），但是改成2.1也报同样的错误。

              export LUAJIT_LIB=/usr/local/LuaJIT/lib
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.1

              这样配置并不起作用，测试了一下还是走else，走auto-discovery
              我自己手动改了config，写死了路就可以了。
