Error message info.json file
Hey! Im completely new to modding and used ChatGPT to update the code of this old mod: https://mods.factorio.com/mod/themighty ... d836e001a4. I would like to test it but the mod doesnt show up in the mod list after i copy it there and i get this error message:
Error ModManager.cpp
Mod package read error. File C:/Users/dalor/AppData/Roaming/Factorio/mods/LongReachSpaceAge.zip/info.json not found. But the info.json file is in the zip. Some assistence would be appreciated.

Re: Error message info.json file
You've got these two lines wrong:
The mod should load if you change them to
Code: Select all
"factorio_version": "2.0.69",
"dependencies": ["base >= 1.0.0"],
Code: Select all
"factorio_version": "2.0",
"dependencies": [
"base >= 2.0.69",
"space-age >= 2.0.69"
],
A good mod deserves a good changelog. Here's a tutorial (WIP) about Factorio's way too strict changelog syntax!

Re: Error message info.json file
Sadly i still get the same error message:
0.122 Error ModManager.cpp
Mod package read error. File C:/Users/dalor/AppData/Roaming/Factorio/mods/LongReachSpaceAge.zip/info.json not found
Is the formatting in the json file of importance? What else could be the issue?

Re: Error message info.json file
Maybe you need like this?:
Its working for me. You can copy this code:
If it still doesnt working, it can be maybe bug or something in prototypes or others folders brokes info.json
You can message me if it still doesnt working
Code: Select all
"factorio_version": "2.0",
"dependencies": ["base", "space-age"]
Code: Select all
{
"name": "ModName", -- Name of your mod
"version": "0.1.0", -- Version of your mod
"title": "ModName", -- Title of your mod
"author": "YourNickName, -- Your nickname
"factorio_version": "2.0", -- Factorio version
"dependencies": ["base", "space-age"] -- mods need for working of these mod
}

~~The mod files need to be inside a folder (named the same as the mod) inside the zip file.~~
JSON files normally cannot include comments. Try deleting the '--' and everything after it.

Re: Error message info.json file
Common mistakes are that
- the last line before the closing brace '}' ends with a comma
- the other lines after the opening brace '{' DO NOT end with a comma
