我正在尝试设置一个包含 lua 5.2、lua 套接字库和一些其他库的 nix-shell 脚本。但是,当我加载 shell 时,最终只显示 Lua。
with import <nixpkgs> {};
stdenv.mkDerivation rec {
name = "lua-env";
buildInputs = [ lua52Packages.lua lua52Packages.luasocket lua52Packages.luasec lua52Packages.cjson ];
}
当我运行 shell 时,我得到的结果如下:
savanni@lapis:~ $ nix-shell lua.nix
[nix-shell:~]$ lua

你必须设置LUA_PATH
并LUA_CPATH
这shell.nix
应该可行,
with import <nixpkgs> {};
with luaPackages;
let
libs = [lua cjson luasocket luasec];
in
stdenv.mkDerivation rec {
name = "lua-env";
buildInputs = libs;
shellHook = ''
export LUA_CPATH="${lib.concatStringsSep ";" (map getLuaCPath libs)}"
export LUA_PATH="${lib.concatStringsSep ";" (map getLuaPath libs)}"
'';
}
要检查这些路径是否已导出,
$ nix-shell --run 'echo $LUA_CPATH; echo $LUA_PATH'

在 2020 年有一种更简单的方法可以做到这一点:
nix-shell -p 'lua.withPackages(ps: [ps.luasocket ps.cjson])'
这会将修改后的lua
派生项放入您的环境中,其中包括luasocket
和cjson
派生项。luaPackages
LUA_PATH
所以你没必要去惹LUA_PATH
你shellHooks
自己。
编辑:
lua.withPackages
您也可以在 nix 文件中使用该函数:
with import <nixpkgs> {};
stdenv.mkDerivation rec {
name = "lua-env";
buildInputs = [ lua.withPackages(ps: with ps; [luasocket luasec cjson ]) ];
}
