YouCompleteMe unavailable: requires Vim 7.4.1578+

[KroniK907]

Issue Details

When I run the vim command I am given:

[user@server]$ vim
YouCompleteMe unavailable: requires Vim 7.4.1578+
Press ENTER or type command to continue

vim --version gives:

VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Dec 21 2016 17:00:20)
Included patches: 1-160

The opening screen of vim shows:
version 7.4.160

:echo v:version shows:
704

I have tried completely removing YCM and re-installing using vundle, as well as running :PluginUpdate

I have also run yum upgrade recently

In my .bashrc file I have the following:
alias vi=vim

My computer is running CentOS 7

[KroniK907]

Vim versioning is stupid. I need to upgrade. Please close this.

Also, its too bad that YCM doesnt work with the most recent version of vim on CentOS 7... I'm going to have to spend an hour trying to get this stupid thing upgraded.

[puremourning]

Your Vim is too old, as the message says :)

[mrmign]

I have the same issue.

But My VI version is newer. I really don't know the problem.

@mrmign you can see here https://github.com/Valloric/YouCompleteMe/blob/master/plugin/youcompleteme.vim#L30 what we do to check the vim version, so can you try to run those commands one by one and see which one is failing?

echo v:version
echo has('patch1578')

also the output of :version would be helpful.

[puremourning]

Seems multiple reports of the issue with 7.4.8056 https://github.com/Valloric/YouCompleteMe/issues/549#issuecomment-317272203. Vim bug?

[puremourning]

7.4.8056 is a very odd version number. There's no tag for it in Vim repo.

[bstaletic]

Exactly. 7.4.8056 never existed. This is most likely something distribution patched. I wonder what v:version has to say.

[puremourning]

Yes. I can reproduce. It's the system Vim version on macOS

[puremourning]

Echo v:version returns 704

As expected has() doesn't say it has the patch. And :version says it is patches 1-898, 8056. So apple have patched Vim and made it incompatible.

Solution: Do what the README.md says: use the latest MacVim. Or use a homebrew Vim or build it yourself.

[TMorville]

Same problem. Did a clean brew install vim and which vimmoved as intended from /usr/bin/vim to /usr/local/bin/vim. However, still get the error

YouCompleteMe unavailable: requires Vim 7.4.1578+.
Info: You appear to be running the default system Vim on macOS. It reports as patch 8056, but it is really older than 1578. Please consider MacVim, homebrew Vim or a self-built Vim that satisfies the minimum requirement.

echo v:version is 704 & echo has('patch1578')is 0.

[bstaletic]

Heh, MacOS fixed the display of Included patches.

@TMorville As the message suggests, your vim is still the default one. Its actual version is 7.4.898.
I've never used macs, but I think you should have ran brew install vim --override-system-vim.
As far as I know, you need to uninstall the brew version and install it again with that switch.

[puremourning]

What @bstaletic said.

[TMorville]

Ran brew remove vim followed by brew install vim --override-system-vim.

The problem remains, same output as above.

[puremourning]

It is because you are still running the wrong vim. This is clearly not a YCM issue.

I actually use macvim (I recommend that) and make an alias.

Try running your correct vim binary with it’s full absolute path to satisfy yourself that this isn’t a YCM bug.

[yantaq]

Try set the following in your ~/.bashrc

• [ ] alias vi="vim"
• [ ] export EDITOR=/usr/local/bin/vim

$ bash ~/.bashrc
