Openresty 學習筆記（四）lualocks包管理器安裝使用

　　Luarocks是一個Lua包管理器，基於Lua語言開發，提供一個命令行的方式來管理Lua包依賴、安裝第三方Lua包等，社區比較流行的包管理器之一，另還有一個LuaDist，Luarocks的包數量比LuaDist多，更細節的二者對比可參閱這裏

　　在作一些openresty的項目的時候，常常會藉助一些第三方包來協助開發，爲了方便管理，咱們能夠使用openresy官方的opm，或者lua的包管理工具luarocks，只不過opm的包數量還不是太多，用的較多的仍是luarocks，如今只能期待opm社區不斷的發展壯大了。

編譯安裝

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
# 安裝須要root權限
sudo make install

安裝參數說明

--prefix 設定 luarocks 的安裝目錄

--with-lua 則是系統中安裝的 lua 的根目錄

--lua-suffix 版本後綴，此處由於openresyt的lua解釋器使用的是 luajit ,因此此處得寫 jit

--with-lua-include 設置 lua 引入一些頭文件頭文件的目錄

查看版本

 luarocks --version
/usr/local/openresty/luajit/bin/luarocks 3.0.0
LuaRocks main command-line interface　　

提示錯誤

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.

 安裝

sudo apt install unzip

執行 luarocks install package 就能夠安裝lua的包了
luarocks install package --tree=path 還能夠指定你安裝的包的存放路徑

下載 rapidjson包

$ luarocks install rapidjson --tree=/usr/local/openresty/lualib/resty

 安裝路徑

$/usr/local/openresty/lualib/resty/lib/luarocks/rocks-5.1
ls
30log  luasocket  manifest  rapidjson

 使用

local rapidjson = require('rapidjson')

rapidjson.encode()
rapidjson.decode()

rapidjson.load()
rapidjson.dump()

》》可能遇到的問題！！！

使用 `www `帳戶安裝 https://github.com/GUI/lua-resty-auto-ssl 擴展的時候一直提示這個錯誤

2018/12/24 10:34:06 [error] 11222#11222: init_by_lua error: init_by_lua:2: module 'resty.auto-ssl' not found:

》》解決方式一：切換成 root 帳戶安裝，`luarocks install lua-resty-auto-ssl`。以上問題解決了　

》》解決方式二：若是使用   sudo ,則使用絕對路徑解決

$ 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.
