Vim error detected

Everytime i quit the vim i got this error, it's just pop up in a second. I already upgrade the vim to the latest version but still got the same error.. How to fix that?

The error message reads:

Error detected while processing function unite#sources#mru#_save[7]..218[7]..219[24]..220:
line    1:
E892: Using a String as a Float

The error message you're seeing refers to a function in the unite#sources#mru namespace, which means it's probably in a MRU plug-in for unite.vim, most probably neomru.vim.

There's an issue reported there that is very similar to yours: issue #48: "Vim error: using String as a Float", reporting code that works in NeoVim but breaks in Vim 8.1. That issue was fixed by this commit, around 5 months ago.

So, try updating your plug-ins and see if that fixes that issue?

If it doesn't, see if these are indeed the plug-ins you have and try to disable them to confirm whether that solves your issue or not.

If you don't really use those plug-ins (and just got them from copying and pasting from somewhere in the web into your vimrc), consider disabling/removing them, no point in keeping them around if you don't use them...

If you still can't figure it out, you need to post a more detailed question, including more information about your system, which plug-in manager you're using (if any), which plug-ins you have installed, perhaps relevant snippets from your vimrc, etc.

  • I tried to remove unite plugin on .vim dir and it's solved the problem. But i still don't know if there's a unite plugin left somewhere since i don't know how that plugin is installed. The plugin comes along with the OS. I'm using NeoBundle

  • If removing it from .vim solved the problem, then it sounds like you got your answer, right? Was there something else you wanted to get accomplished here?

  • I thought unite was deprecated anyway, for denite? Maybe im wrong.
