  • lua 5.3.5 安装/初体验

    安装

    官网http://www.lua.org/start.html 参考  https://blog.csdn.net/qq_23954569/article/details/70879672

    cd ~
    sudo apt-get install -y libreadline7 libreadline-dev
    wget http://www.lua.org/ftp/lua-5.3.5.tar.gz
    tar zxf lua-5.3.5.tar.gz
    cd lua-5.3.5
    sudo make linux test
    sudo make install

    因为放在了home,所以重装之后,只需要执行最后1句就OK了

    包管理luarocks

    才1M

    cd ~
    wget https://luarocks.org/releases/luarocks-3.0.4.tar.gz
    tar zxpf luarocks-3.0.4.tar.gz
    cd luarocks-3.0.4
    ./configure; sudo make bootstrap
    sudo luarocks install luasocket

     安装luasql-postgres

    安装时要求本地有postgres源码 

    Error: Could not find header file for PGSQL
    No file libpq-fe.h in /usr/local/include
    No file libpq-fe.h in /usr/include
    No file libpq-fe.h in /include
    You may have to install PGSQL in your system and/or pass PGSQL_DIR or PGSQL_INCDIR to the luarocks command.
    Example: luarocks install luasql-postgres PGSQL_DIR=/usr/local

    但是我的pg是在docker镜像里的, 所以怎么办呢?要么在host上装pg,但完全没必要.超极本上资源已经很紧了,只写代码,不做数据库.

    在安装时指定PG路径, 注意不是PGSQL_DIR

    sudo apt-get install libpq-dev
    sudo luarocks install luasql-postgres PGSQL_INCDIR=/usr/include/postgresql PGSQL_LIBDIR=/usr/lib

    连接db简单使用

    luasql = require "luasql.postgres"
    env = assert(luasql.postgres())
    -- database user pwd host port
    conn = assert(env:connect("postgres","postgres","example",'127.0.0.1'))
    
    -- version
    cur = conn:execute("SELECT version();")
    print(cur:fetch())
