我是luarocks的新手,我刚刚尝试安装luarepl。安装显然很顺利:

$ luarocks install luarepl
Installing https://luarocks.org/luarepl-0.8-1.rockspec...
Using https://luarocks.org/luarepl-0.8-1.rockspec... switching to 'build' mode
Updating manifest for /Users/me/.luarocks/lib/luarocks/rocks-5.1
luarepl 0.8-1 is now built and installed in /Users/me/.luarocks (license: MIT/X11)

但如果我尝试启动可执行文件,安装似乎已中断:

$ ~/.luarocks/bin/rep.lua
/usr/local/bin/lua5.1: ...cks/lib/luarocks/rocks-5.1/luarepl/0.8-1/bin/rep.lua:23: module 'repl.console' not found:

我可以找到那些东西。我尝试在配置中添加一行。lua将从本地安装加载包,但无效:

$ cat ~/.luarocks/config.lua
local_by_default=true

我是否错过了一些明显的步骤?

跑步 luarocks 没有任何论据给了我:

CONFIGURATION
    Lua version: 5.1
    Configuration files:
        System: /usr/local/etc/luarocks51/config-5.1.lua (ok)
        User  : /Users/me/.luarocks/config.lua (ok)

    Rocks trees in use:
        /Users/me/.luarocks ("user")
        /usr/local ("system")

用户rock树似乎不在包路径中:

$ lua
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> print(package.path)
./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua

为什么?

从…起 https://github.com/luarocks/luarocks/wiki/Using-LuaRocks :

大多数LuaRocks装置将配备两棵岩石树:

“系统”岩石树(默认使用)
“用户”岩石树

为了能够使用该模块,我们需要确保Lua能够找到dkjson。当我们运行时lua文件 require("dkjson") . 您可以使用从Lua环境检查Lua路径

print(package.path)
print(package.cpath)

这些变量可以使用 LUA_PATH 和 LUA_CPATH 环境变量。

如果您将Lua和Luarock安装在它们的默认目录中(/usr/local,在Linux和Mac OSX上),那么“系统”树是/usr/local,默认情况下它会工作。但是,默认情况下,Lua不会检测到“用户”树(用于在没有管理员权限的情况下安装rocks)。为此,我们需要配置这些环境变量。

LuaRocks提供了一种半自动化的方法来实现这一点。如果键入以下命令:

luarocks path --bin

它将打印适合您的平台的命令,用于设置您的环境。在典型的Unix终端环境中,可以键入以下内容:

eval $(luarocks path --bin)

它会将更改临时应用到shell。要永久设置这些变量,必须将环境变量配置到shell配置中(例如,如果shell是Bash,则将上述行添加到.bashrc文件)。
