This error can be ignored as i did not had Prismatic Belts: Space Age installed (auto updated failed to install it after updating Prismatic Belts)

I am getting the following error up on loading space age DLC

Failed to load mods: prismatic-belts/prototypes/mods/space-age.lua:13:

Missing required dependency:
Using Prismatic Belts with Space Age requires the additional asset mod "Prismatic Belts: Space Age".

Click on "Manage", and install and/or enable "Prismatic Belts: Space Age".

You need this also.

yea i saw it that it did not got installed after the autoupdate of Prismatic Belts it self

Make sure they're both enabled.

能否在下次更新时将其加入到MOD强制依赖列表里？如果不是看到这个帖子，我还一直以为是MOD本身有问题。

No, i can't add it as a required dependency in the main mod. Because space age is a completely separate executable. The error message, if you read it, literally tells you what to do.
