Linux 安裝 luarocks(lua的模塊管理工具)

一、簡介

該軟件包能夠安裝和更新lua的第三方模塊。

 

二、下載地址

請在 http://luarocks.org/releases/ 頁面選擇須要的軟件包。

wget http://luarocks.org/releases/luarocks-2.1.0.tar.gz

 

三、安裝

tar -zxvf luarocks-2.1.0.tar.gz

cd luarocks-2.1.0

./configure --prefix=/usr/local/luarocks

make build

make install

OK了,luarock的可執行文件被安裝到了 /usr/local/luarocks/bin/luarocks.

 

四、使用(暫時把英文直接copy過來，有時間再翻譯)

使用luarocks安裝lua模塊的示例:

 

luarocks install luasocket

luarocks install luasql-sqlite3

luarocks install lpeg

luarocks install lzlib

luarocks install luafilesystem

luarocks install luasec

luarocks install md5

luarocks install luacurl

luarocks install luasql-mysql MYSQL_INCDIR=/usr/include/mysql MYSQL_LIBDIR=/usr/lib64/mysql/ (mysql的各類路徑本身locate去找吧 = = ！)

luarocks install lua-cjson

 

1.模塊安裝後若是在程序require的時候提示找不到相應模塊則能夠在luarocks和lua之間作一個軟連接:

例如安裝完luasql-mysql以後可能在程序中require的時候會提示找不到模塊，這時候咱們能夠：

cd /usr/local/lib/lua/5.1/

mkdir luasql

ln -s /usr/local/luarocks/lib/lua/5.1/luasql/mysql.so /usr/local/lib/lua/5.1/luasql/mysql.so

 

2.運行時提示attempt to index global 'luasql' (a nil value) 代碼裏面require "luasql.mysql"須要這樣寫

luasql = require "luasql.mysql"

 

Usage

luarocks [--server=server | --only-server=server] [--tree=tree] [--only-sources=url] [--deps-mode=mode] [VAR=VALUE]...command [argument]

 

Variables from the "variables" table of the configuration file can be overriden with VAR=VALUE assignments.

--server=server	Fetch rocks/rockspecs from this server (takes priority over config file)
--only-server=server	Fetch rocks/rockspecs from this server only (overrides any entries in the config file)
--only-sources=url	Restrict downloads of sources to URLs starting with the given URL. For example, --only-sources=http://luarocks.org will allow LuaRocks to download sources only if the URL given in the rockspec starts with http://luarocks.org .
--tree=tree	Which tree to operate on.
--deps-mode=mode	Select dependencies mode: How to handle the list of rocks servers given in the rocks_servers array in theconfig file. one - Consider only the tree at the top of the list (possibly, the one given by the --tree flag, overriding all entries from rocks_trees), ignore all others all - Consider all trees: if a dependency is installed in any tree of the rocks_trees list, we have a positive match. order - Consider only trees starting from the "current" one in the order, where the "current" is either: the one at the bottom of the rocks_trees list, or one explicitly given with --tree or the "home" tree if --local was given or local_by_default=true is configured (usually at the top of the list)

 

Supported commands

 

 

build	Build/compile and install a rock.
download	Download a specific rock or rockspec file from a rocks server.
help	Help on commands.
install	Install a rock.
list	Lists currently installed rocks.
make	Compile package in current directory using a rockspec and install it.
pack	Create a rock, packing sources or binaries.
path	Return the currently configured package path.
remove	Uninstall a rock.
search	Query the LuaRocks repositories.
show	Shows information about an installed rock.
unpack	Unpack the contents of a rock.

 

Overview of the difference between "make", "build", "install" and "pack"

 

 

luarocks install modulename	downloads a binary .rock file and installs it to the local tree (falls back to "luarocks build modulename" behavior if a binary rock is not found)
luarocks build modulename	downloads a .src.rock or a rockspec and builds+installs it to the local tree.
luarocks build modulename-1.0-1.linux-x86.rock	extracts the rockspec from the rock and builds it as if the rockspec was passed in the command-line (i.e., redownloading sources and recompiling C modules if any).
luarocks build modulename-1.0-1.rockspec	builds+installs the rock using the given rockspec downloading the sources
luarocks make modulename-1.0-1.rockspec	builds+installs the rock using the rockspec using the contents of your current directory (kind of like the way make uses a Makefile) instead of downloading sources
luarocks pack modulename	grabs the rock from your local tree and packs it into a binary .rock file
luarocks pack modulename-1.0-1.rockspec	downloads the sources from the url and packs it into a .src.rock file
