luarocks yum 安装引起的lapis lua 包查找问

备注：

大家在进行lapis 开发的时候有些人比较懒直接使用yum 按照luarocks，之后

使用luarocks 安装lapis 一般来说对于linux 64位的环境都会有些问题（包找不到）

1. 错误提示信息

2. 分析

从上面的错误提示可以看出，主要是包的问题，实际上报是已经安装了，原因64位操作系统，以及luarocks默认安装包的

位置不是框架查找的地方

我们系统安装的位置：

lapis：

/usr/share/lua/5.1/lapis

lpeg:

/usr/lib64/lua/5.1/lpeg.so

3. 解方法

a.不用yum安装而是源码，可控性强，维护简单，参考相关文档

b.nginx.conf添加lua_path、lua_cpath。。。，不太喜欢，费事

c.配置luaroacksluapath也是一种方法

d.使用软连接

4. 实际解决（使用d,其他的参考相关文章）

ln -s /usr/lib64/lua    /usr/local/lib/lua

ln -s /usr/share/lua   /usr/local/share/lua
