Pretty much that. when you uploaded your mod you didn't include a version number somewhere. Your mod can't be downloaded via the ingame mod portal.

Hi Ashotep
I am confused. If you check the json file, there is a version number. Can you be more explicit?
Thanks

I guess a picture is worth a 1000 words

if you look at the version there is a dash through it. So the ingame browser won't let you install it. I had not problems installing it manually though.

That was my first though also, so I opened the .json and saw a version so I wasn't sure what the issue was/is.

So for this issue what a lot of mods seem to have in their info.json is:

"factorio_version": "0.15",
"dependencies": "base >= 0.15.0"
If you look at the Base mod, it requires factorio 15, and it's version is 0.15.X (the factorio version number)

Your info.json has "dependencies": ["base"],
This is probably what is stopping the mod portal from allowing in-game installations of your mod. You have base as a dependency, but the portal has 0.14 and 0.15 base mods, and it needs to know WHICH base the mod needs.

Same error.

I think it should work, if you change info json like so:
...
"factorio_version": "0.15"
...

Refer to what you see, if you watch your mod inside Factorio. :) There is still a discrepancy in check-code between download/install and loading.
