1、簡介
該軟件包可以安裝和更新lua的第三方模塊。
2、下載地址
請在 http://luarocks.org/releases/ 頁面選擇需要的軟件包。
wget http://luarocks.org/releases/luarocks-2.1.0.tar.gz
3、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.
4、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的各種路徑自己locate去找吧 = = !)
luarocks install lua-cjson
1.模塊安裝後如果在程序require的時候提示找不到相應模塊則可以在luarocks和lua之間做一個軟鏈接:
例如安裝完luasql-mysql之後可能在程序中require的時候會提示找不到模塊,這時候我們可以:
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.運行時提示attempt to index global 'luasql' (a nil value) 代碼裡面require "luasql.mysql"需要這樣寫
luasql = require "luasql.mysql"
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.
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.
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
