Openresty 学习笔记（四）lualocks包管理器安装使用
Luarocks是一个Lua包管理器，基于Lua语言开发，提供一个命令行的方式来管理Lua包依赖、安装第三方Lua包等，社区比较流行的包管理器之一，另还有一个LuaDist，Luarocks的包数量比LuaDist多，更细节的两者对比可参阅这里
在做一些openresty的项目的时候，经常会借助一些第三方包来协助开发，为了方便管理，我们可以使用openresy官方的opm，或者lua的包管理工具luarocks，只不过opm的包数量还不是太多，用的较多的还是luarocks，现在只能期待opm社区不断的发展壮大了。
编译安装
wget https://github.com/luarocks/luarocks/archive/v3.0.0.tar.gz
tar zxvf v3.0.0.tar.gz
cd luarocks-3.0.0/
./configure --prefix=/usr/local/openresty/luajit \
--with-lua=/usr/local/openresty/luajit/ \
--lua-suffix=jit \
--with-lua-include=/usr/local/openresty/luajit/include/luajit-2.1
make build
# 安装需要root权限
sudo make install
安装参数说明
--prefix 设定 luarocks 的安装目录
--with-lua 则是系统中安装的 lua 的根目录
--lua-suffix 版本后缀，此处因为openresyt的lua解释器使用的是 luajit ,所以此处得写 jit
--with-lua-include 设置 lua 引入一些头文件头文件的目录
查看版本
luarocks --version
/usr/local/openresty/luajit/bin/luarocks 3.0.0
LuaRocks main command-line interface
提示错误
Configuring LuaRocks...
Lua version detected: 5.1
Lua interpreter found: /usr/local/openresty/luajit/bin/luajit
lua.h found: /usr/local/openresty/luajit/include/luajit-2.1/lua.h
Could not find 'unzip'.
Make sure it is installed and available in your PATH.
configure failed.
安装
sudo apt install unzip
执行 luarocks install package 就可以安装lua的包了luarocks install package --tree=path 还可以指定你安装的包的存放路径
下载 rapidjson包
$ luarocks install rapidjson --tree=/usr/local/openresty/lualib/resty

》》解决方式一：切换成 root 账户安装，`luarocks install lua-resty-auto-ssl`。以上问题解决了
》》解决方式二：如果使用 sudo ,则使用绝对路径解决
$ sudo /usr/local/openresty/luajit/bin/luarocks install lua-resty-auto-ssl
Warning: The directory '/home/www/.cache/luarocks' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing /usr/local/openresty/luajit/bin/luarocks with sudo, you may want sudo's -H flag.
