Error when requiring module

[L3G5ND]

When I require the module I get this error:

C:\Lua51\lua5.1.exe: error loading module 'lcurl' from file 'C:\Lua51\systree\lib\lua\5.1\lcurl.dll':
        The specified module could not be found.

stack traceback:
        [C]: ?
        [C]: in function 'require'
        C:\Lua51\systree\share\lua\5.1\curl.lua:11: in main chunk
        [C]: in function 'require'
        main.lua:2: in main chunk
        [C]: ?

I installed Lua-cURL with Windows 32 bit cURL: luarocks install lua-curl CURL_DIR=C:\curl-7.82.0_1-win32-mingw

Seems like when I installed it, it didn't install a lcurl file. How do I fix this?

I am also running into this error (not being able to find lcurl). I am installed on Mac OS 11.3 using homebrew/luarocks. To reproduce:

1. brew install luarocks & brew install curl
2. luarocks install lua-curl CURL_INCDIR=/opt/homebrew/opt/curl/include This produces the following:

3. Run the lua script containing local curl = require("curl"). This produces:

N.B. In my case, the lua script is a script for LuaLaTeX.

Using find /opt/homebrew -name lcurl and similar, I can find no lcurl files installed whatsoever.

I suspect this is related to #183, as I also had to separately install cURL (via homebrew, see above), perhaps something isn't working at that step and lua-curl depends on it?

Any help would be greatly appreciated as I would love to use this library in my project!

Search your entire system for lcurl.so You can tell from the log it successfully compiled lcurl.so without any error. Usually it's because you don't configure the path correctly luarocks path
