Question

要安装luarocks，我从here下载了最新的（2.0.11）tar.gx文件。我打开包装，按照说明操作。

$ ./configure

Using Lua from: /usr/local

Done. You can now run 'make' to build.

然后我运行了sudo make install，最后尝试安装了一个软件包但是当我尝试运行它时出现了这个错误：

$ sudo luarocks install lpeg
/usr/local/bin/lua: /usr/local/share/lua/5.1//luarocks/cfg.lua:355: attempt to call global 'tonumber' (a nil value)
stack traceback:

    [C]: in function 'require'
    /usr/local/bin/luarocks:4: in main chunk
    [C]: ?

手动运行lua，tonumber和其他一切一样正常。我不知道为什么它在这里失败了。

在cfg.lua的顶部，您需要添加

local tonumber = tonumber

在module来电之前

。您可以在类似的本地定义列表的两行中包含tonumber。您可以在/usr/local/share/lua/5.1//luarocks/cfg.lua或源版本和make install中的已安装版本中再次进行这些更改。

这是luarocks中的一个错误，将在下一个版本中修复。

我修改过的luarocks-2.0.11 / src / luarocks / cfg.lua包含：

local rawset, next, table, pairs, require, io, os, setmetatable, pcall, ipairs, package, type, assert, tonumber, _VERSION =
      rawset, next, table, pairs, require, io, os, setmetatable, pcall, ipairs, package, type, assert, tonumber, _VERSION

module("luarocks.cfg")

无法运行luarocks，tonumber是零值
