the same here. I have freshly installed Mint 18. I followed the installation instruction (https://github.com/neovim/neovim/wiki/Installing-Neovim#ubuntu) and bumped into "YouCompleteMe unavailable: requires Vim compiled with Python (2.6+ or 3.3+) support":

Error detected while processing /home/nad2000/dotfiles/.vim/init.vim:

@nad2000 Did you follow the instructions for using Python 2/3 plugins with Neovim?

[nad2000]

@micbou I followed but I made a blunder using both "sudo" and "--user". My bad.

To summarise (assuming you are running Ubuntu 12.04 or later) you should run:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:neovim-ppa/unstable
sudo apt-get update
sudo apt-get install neovim
sudo apt-get install python-dev python-pip python3-dev python3-pip

And for Python support:

pip install --user -U neovim
pip3 install --user -U neovim

Or, to make it systemwide (generally it's frown upon to use sudo pip install ...):

sudo pip install -U neovim
suod pip3 install -U neovim

For any updates on the installation see: https://github.com/neovim/neovim/wiki/Installing-Neovim#ubuntu and https://neovim.io/doc/user/provider.html#provider-python

To verify the setup run:

python -c "import neovim"
python3 -c "import neovim"

@nad2000 this does not help on Ubuntu

[nad2000]

@tastyminerals try to run:

python -c "import neovim"
python3 -c "import neovim"  ## if you are using Python3

Cheers!

sudo apt-get install vim-nox
vim-nox has python support which will enable python.

Having this problem on updating youcompleteme (worked previously):

Environment: neovim (v0.3.4), with no special python settings (checkhealth finds python), youcompleteme from git

• last working version: commit 113787cc
• first broken version: commit d4e3d85f

haven't tried bisecting yet, will do once I have time

We've already had a few reports. #3306 is currently running the tests and once they pass it will be merged.

Sorry to necro, but I'm running into this problem again.

I'm running nvim version 0.4.0-dev, build git201909072024-158b780-6e51973.

I'm running YCM commit 5274b73fc26deb5704733e0efbb4b2d53dc6dc9c.

I've gone and uninstalled/reinstalled pynvim and made sure that there aren't any old neovim installs lying around.

When I run :checkhealth, both the python2 and python3 checks come back green.

I'm still getting this message on startup:

YouCompleteMe unavailable: requires Vim compiled with Python (2.7.1+ or 3.5.1+) support. 

[bstaletic]

It's a neovim bug.

See https://github.com/neovim/neovim/pull/10942#issuecomment-529479500 and #3484

Thank you for the clarification!
