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,只有Lua最终存在.
with import <nixpkgs> {};
stdenv.mkDerivation rec {
name = "lua-env";
buildInputs = [ lua52Packages.lua lua52Packages.luasocket lua52Packages.luasec lua52Packages.cjson ];
}
当我运行shell时,这就是我得到的：
savanni@lapis:~ $nix-shell lua.nix
[nix-shell:~]$lua

解决方法
您必须设置LUA_PATH和LUA_CPATH
这个shell.nix应该可以工作,
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' /nix/store/lp0ns0hjwx1klk6amnyic3f62bw7h8j7-lua-5.2.3/lib/lua/5.2/?.so;/nix/store/lp0ns0hjwx1klk6amnyic3f62bw7h8j7-lua-5.2.3/share/lua/5.2/?.so;/nix/store/ppdspfcm5nnfz0fk9zarjmpyv5lcmn18-lua5.2-cjson-2.1.0/lib/lua/5.2/?.so;/nix/store/ppdspfcm5nnfz0fk9zarjmpyv5lcmn18-lua5.2-cjson-2.1.0/share/lua/5.2/?.so;/nix/store/b71xyq7gkc8iccj6wr84zq31gqc3m9ix-lua5.2-socket-3.0-rc1/lib/lua/5.2/?.so;/nix/store/b71xyq7gkc8iccj6wr84zq31gqc3m9ix-lua5.2-socket-3.0-rc1/share/lua/5.2/?.so;/nix/store/6q8xn2bcfskmrfzql47jld5d2irvn5jr-lua5.2-sec-0.6/lib/lua/5.2/?.so;/nix/store/6q8xn2bcfskmrfzql47jld5d2irvn5jr-lua5.2-sec-0.6/share/lua/5.2/?.so /nix/store/lp0ns0hjwx1klk6amnyic3f62bw7h8j7-lua-5.2.3/lib/lua/5.2/?.lua;/nix/store/lp0ns0hjwx1klk6amnyic3f62bw7h8j7-lua-5.2.3/share/lua/5.2/?.lua;/nix/store/ppdspfcm5nnfz0fk9zarjmpyv5lcmn18-lua5.2-cjson-2.1.0/lib/lua/5.2/?.lua;/nix/store/ppdspfcm5nnfz0fk9zarjmpyv5lcmn18-lua5.2-cjson-2.1.0/share/lua/5.2/?.lua;/nix/store/b71xyq7gkc8iccj6wr84zq31gqc3m9ix-lua5.2-socket-3.0-rc1/lib/lua/5.2/?.lua;/nix/store/b71xyq7gkc8iccj6wr84zq31gqc3m9ix-lua5.2-socket-3.0-rc1/share/lua/5.2/?.lua;/nix/store/6q8xn2bcfskmrfzql47jld5d2irvn5jr-lua5.2-sec-0.6/lib/lua/5.2/?.lua;/nix/store/6q8xn2bcfskmrfzql47jld5d2irvn5jr-lua5.2-sec-0.6/share/lua/5.2/?.lua
