YouCompleteMe unavailable: requires Vim compiled with Python (3.6.0+) support - python-3.x

i have vim 8.2.850. I am trying to install YouCompleteMe. But get this error, when trying to open vim:
"YouCompleteMe unavailable: requires Vim compiled with Python (3.6.0+) support"
How can i fix this? i saw other ppl answer for different versions. But sorry im a noob, could someone please help and give a detailed explaination on how to fix it?
And i am on mac, using terminal

It is an old question but I wanted to add I simply installed macvim and re-started terminal again. It solved my problem
- brew install macvim

I'm aware that this isn't directed at your question per say, but I ran into the same issue on Ubuntu with nvim.
Reinstalling didn't help, but adding https://github.com/neovim/pynvim fixed my issue.
Perhaps it can be helpful to Mac users using nvim too.

you can use vim --version | grep python to check your vim. If vim detects the python3, it will show like:
+cmdline_hist +langmap -python +viminfo
+cmdline_info +libcall +python3 +virtualedit
The python3 will have a + sign in front of that.
If not, first, you must check if you have python3.
Second, you need to uninstall vim (sudo apt purge vim), then reinstall vim (sudo apt install vim).
Third. Reconfirmation by vim --version | grep python.
I hope this can help you.

Yes, you can reinstall the latest vim version with homebrew: https://formulae.brew.sh/formula/vim
But, I think you should recheck your vim version with :version, there is no version like yours.
And the latest version itself depends on python, and more like nvim.
# I do like this
brew install vim --HEAD

Confirmed
brew install macvim
worked for me after restarting terminal.
Make sure to
brew uninstall vim
before installing macvim, then restart terminal.
Solved it for me on new Mac with new apple chip.

Thankfully, the error message is pretty solid. You need vim with Python,
Now while I don't personally have a mac that should be as straightforward as making sure you install the correct version.
The simplest way is probably going to be with brew as mentioned here.
brew remove vim
brew cleanup
brew install vim --with-python
If you installed it with a binary you will need to find a new binary with python included. Or alternatively you could try and build it from source as the comment from Zoe suggested. But I think that may be somewhat more involved than ideal for a beginner, although worthwhile.
It doesn't seem, like this actually involves neovim at all, If it does then you may want to update your question, otherwise it is a good idea to remove the neovim tag.

YouCompleteMe unavailable: module 'collections' has no attribute 'Mapping'

Hi I have been trying to setup YouCompleteMe in vim but it don't work. I am using vim-plug. I tried around 3 different YouCompleteMe repositories but i always got the same error. I am using a Mac os and everything about vim is up to date. I tried adding scripts in .vimrc, running install.py but non of em worked. I really need Help. Here is my .vimrc script and the error
The easiest way to fix the problem is to install youcompleteme in the following way.
In a Terminal, run the command:
$ sudo apt install vim-youcompleteme
Next, run the command:
$ vim-addon-manager install youcompleteme
I got my exactly the same problem fixed a minute ago by running the above two commands, thanks to dominoc925's youcompleteme installation instructions.

Installing Vim with Python3 support?

I installed Vim on my MacBook today (using brew install vim), but I am having a problem: vim --version tells me that there is no Python 3, which I need. I already reinstalled the newest version of Python from their website, then did brew delete vim and brew cleanup and reinstalled Vim, but I'm still having the same problem. Online, I saw the option to use the flag --with-python3 when installing, but when I try that, I get told that this flag doesn't exist. Now I don't know what to do. Do I need to install Python via Homebrew? I also found some people online saying that there are versions of Vim compiled without Python, and that you can compile Vim yourself. Do I need to do that? How?
I should add: I'm very new to this, so if you post your answers or maybe need some more information from me, please explain in detail so I can understand.
I'm a new too.
First, use brew to remove vim you should input brew uninstall vim.Then try to reinstall vim.
For instance, if you wanted to recompile Vim 8 with Python 3 support on Linux, you can try do the following:
$ git clone https://github.com/vim/vim.git
$ cd vim/src
$ ./configure --with-features=huge --enable-python3interp
$ make
$ sudo make install
So,
I include this answer to "Way 0" and "Way 1".
_______________________________________________________________---Way 0 Begin---(:
Way 0:
we should reinstall python3 and VIM,
1.run the below on terminal
brew reinstall python3
the upstairs shows that we reinstall python3 to make sure that needed by VIM.
2.continue run on terminal
brew uninstall vim
the upstairs shows that uninstall vim only if you previously installed it
3.run on terminal
brew install vim
the upstairs shows that reinstall vim via Homebrew
4.run on terminal
4.1 directly use $SHELL command
alias vim=/usr/local/bin/vim
4.2 or bash 's profile(if you use bash as SHELL)
echo 'export PATH="/usr/local/opt/vim/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
4.3 OR zsh configuration file(if you use zsh as SHELL)
edit your zsh configuration file ~/.zshrc via
vim ~/.zshrc
and add the below to TOP line(just use i to enter editing status,
then use ":wq" to quit editing status and save file):
export VIM_HOME=/usr/local/Cellar/vim/8.2.2100/
export PATH=$PATH:$VIM_HOME/bin
and active that config
source ~/.zshrc
(Both 4.1 or 4.2 or 4.3 are the same function.)
the upstairs 4.1/4.2/4.3 shows that we let shell command vim using HomebrewVIM not the defaultVIM.
We know the default VIM functional file is located at /usr/bin/vim,
while homebrew VIM functional file is located at /usr/local/bin/vim;
And default VIM support Python2 with not supporting Python3,
but homebrew VIM support Python3(That's also we needed!).
Let's look at Homebrew VIM:
Homebrew will install VIM vim at /usr/local/Cellar/vim,
create soft link vim under /usr/local/opt,
and Homebrew VIM 's functional file vim is located at /usr/local/bin/vim, also linked to /usr/local/Cellar/vim.
5.exit terminal and restart terminal or even restart mac, input
the below on terminal
vim --version | grep "python3"
checkout whether the symbol bdfore "python3" is + or Not?
"+" means VIM support python3, but "-" Not.
____________________________________________________________---Way 0 END---:)
____________________________________________________---Way 1 Start---(::
Way 1:
First, you need to use this to checkout whether VIM support Python3 or not?
vim --version | grep python
you may see the terminal output liking:
+conceal +linebreak -python3 +visual
as the upstairs shows: that Mac default installed VIM DO NOT SUPPORT Python3.
And that default installed VIM of Mac is not been installed via "brew".
Now, we could not use liking "brew remove" to delate that default installed VIM of Mac,
and it's also why your action
"brew delete vim and brew cleanup and reinstalled Vim"
DO NOT FUNCTION!
Second,
we need to know where that fu-king default installed VIM with not supporting python3,
which vim
output:
/usr/bin/vim
mostly shows like the upstairs(depends default macOS).
Even we use "--with-python3 " to install VIM with supporting
Python3at a long time, but Now Homebrew ONLY recognize "python -V"'s version.
SO we NEED to manually let default python to be python3.
Open your terminal and input:
alias python="python3"
then checkout python that that version whether is python3 or not:
python -V
then, we found that "python -V" shows "Python 3.9.12".
Third,
That's time to use Homebrew to install VIM.
brew install vim
After installing HomebrewVIM, we need to make sure where is HomebrewVIM,
differ from that default installed VIM of Mac:
which vim
output:
/usr/local/bin/vim
Please restart Your Mac, restart Your Terminal and reenter your terminal!!!
Please restart Your Mac, restart Your Terminal and reenter your terminal!!!
Please restart Your Mac, restart Your Terminal and reenter your terminal!!!
then, we need to checkout whether that HomebrewVIM supports Python3 or Not:
vim --version | grep python
output:
+conceal +linebreak +python3 +visual
Successful!

Reinstall vim with python3 support

I installed Vim 7.4 a few months ago (sudo apt-get install vim) on Ubuntu 16.04 and now I'm trying to install plugins that require python3 support.
How can I reinstall/uppgrade vim to support python3?
sudo apt install vim-nox
Fixed it for me. Didn't even have to uninstall my current vim or anything else. Thanks to Romainl for your comment!

how to install xcape on mac?

I'm recently learning to use VIM editor which is so great. Just as other vimmers, I find it's a little unpleasant to press the esc and ctrl key because they are a little far away. I find a solution is to map both esc and ctrl to caps lock with the help of xcape.
But I'm not sure how to install it. Because the homepage of xcape is using apt-get to install necessary packages. I think on mac, apt-get is not available. I have homebrew installed, however there's no xcape package on homebrew.
So I'm just not sure how to install xcape, could anyone help?
btw, how to make it work on windows?
xcape will be of no use on a Mac. Try Seil instead.

Create macvim in Applications folder

I ran brew install macvim, and I'm wondering if there's a way to access it outside of the terminal? I know I can create a link in my applications folder, but is there more native support for this? Or is my best bet just to download this guy https://code.google.com/p/macvim/ ?
MacVim is actually a GUI application first, that comes with a CLI executable that you can run in your shell.
You can find the MacVim.app bundle in /usr/local/Cellar/, where Homebrew puts all the programs you install with it.
It is also possible to launch the MacVim GUI with:
$ mvim -g filename
Installing MacVim with Homebrew makes sense if you already use Homebrew to install the UNIX programs that you use regularly but installing Homebrew just to get MacVim is a pointless waste of time. Downloading MacVim from the official source is a much better idea IMO: simpler, quicker…
