lua安装教程 linux,Linux 安装 luarocks(lua的模块管理工具)
1、简介
该软件包可以安装和更新lua的第三方模块。
2、下载地址
请在 http://luarocks.org/releases/ 页面选择需要的软件包。
wget http://luarocks.org/releases/luarocks-2.1.0.tar.gz
3、安装
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的可执行文件被安装到了 /usr/local/luarocks/bin/luarocks.
4、使用(暂时把英文直接copy过来，有时间再翻译)
使用luarocks安装lua模块的示例:
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的各种路径自己locate去找吧 = = ！)
luarocks install lua-cjson
1.模块安装后如果在程序require的时候提示找不到相应模块则可以在luarocks和lua之间做一个软链接:
例如安装完luasql-mysql之后可能在程序中require的时候会提示找不到模块，这时候我们可以：
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.运行时提示attempt to index global 'luasql' (a nil value) 代码里面require "luasql.mysql"需要这样写
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/compile and install a rock.
Download a specific rock or rockspec file from a rocks server.
Help on commands.
Install a rock.
Lists currently installed rocks.
Compile package in current directory using a rockspec and install it.
Create a rock, packing sources or binaries.
Return the currently configured package path.
Uninstall a rock.
Query the LuaRocks repositories.
Shows information about an installed rock.
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
