`corelgilua51`

Question

我正在尝试运行以下代码

local lgi = require("lgi")
local Gdk = lgi.Gdk
local Gtk = lgi.Gtk

Gtk.init()

-- Create a new window
local window = Gtk.Window({
    title = "LGI Test Window",
    default_width = 300,
    default_height = 200,
    on_destroy = Gtk.main_quit,
})

-- Create a label and add it to the window
local label = Gtk.Label({ label = "Hello, LGI!" })
window:add(label)
window:show_all()
Gtk.main()

但这给了我以下错误

lua: /home/username/.luarocks/share/lua/5.3/lgi/core.lua:14: module 'lgi.corelgilua51' not found:
    no field package.preload['lgi.corelgilua51']

我已经设置了

LUA_PATH

和

LUA_CPATH

，但是从

lgi

安装

luarocks

没有

corelgilua51

，可能是什么问题，lgi只包含以下文件：-

drwxr-xr-x. 1 username username   226 Nov 15 13:01 .
drwxr-xr-x. 1 username username    30 Nov 15 13:05 ..

-rw-r--r--. 1 username username    15 Nov 15 13:01 version.lua

lua版本

5.3.6

，未升级到5.4，因为我尝试使用的项目需要低于5.4的lua版本，从

luarocks

安装时如何可以缺少模块，任何帮助将不胜感激。如果需要任何其他信息，请询问。

Answer 1

这个问题的原因是lgi的Makefile中的lib目录被硬编码为

/usr/local/lib/lua/5.1

。

PREFIX = /usr/local
LUA_VERSION=5.1
LUA_LIBDIR = $(PREFIX)/lib/lua/$(LUA_VERSION)
LUA_SHAREDIR = $(PREFIX)/share/lua/$(LUA_VERSION)
...
mkdir -p $(DESTDIR)$(LUA_LIBDIR)/lgi
cp $(CORE) $(DESTDIR)$(LUA_LIBDIR)/lgi

正如你在问题中看到的，当你在另一个版本的Lua中使用它时，它搜索的目录是

/usr/local/lib/lua/5.3/lgi.so

，这导致了错误。解决办法可以是修改Makefile中

LUA_VERSION

的值，或者将输出文件复制到正确的目录，或者更改

package.searchpath

。
