安装部署要点（README 精选）

Supported Python runtime

YCM has two components: A server and a client. Both the server and client
require Python 3.12 or later 3.x release.

For the Vim client, Vim must be, compiled with --enable-shared (or
--enable-framework on macOS). You can check if this is working with :py3 import sys; print( sys.version). It should say something like 3.12.0 (...).

For Neovim, you must have a python 3.12 runtime and the Neovim python
extensions. See Neovim’s :help provider-python for how to set that up.

For the server, you must run the install.py script with a python 3.12 (or
later) runtime. Anaconda etc. are not supported. YCM will remember the runtime
you used to run install.py and will use that when launching the server, so if
you usually use anaconda, then make sure to use the full path to a real cpython3,
e.g. /usr/bin/python3 install.py --all etc.

Our policy is to support the python3 version that’s available in the latest
Ubuntu LTS (similar to our Vim version policy). We don’t increase the Python
runtime version without a reason, though. Typically, we do this when the current
python version we’re using goes out of support. At that time we will typically
pick a version that will be supported for a number of years.

Quick start, installing all completers

Install YCM plugin via [Vundle][]
Install CMake, MacVim and Python 3; Note that the pre-installed macOS system
Vim is not supported (due to it having broken Python integration).

$ brew install cmake python go nodejs

Install mono from Mono Project (NOTE: on Intel Macs you
can also brew install mono. On arm Macs, you may require Rosetta)
For Java support you must install a JDK, one way to do this is with Homebrew:

$ brew install java
$ sudo ln -sfn $(brew --prefix java)/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Pre-installed macOS system Vim does not support Python 3. So you need to
install either a Vim that supports Python 3 OR [MacVim][] with
[Homebrew][brew]:
Option 1: Installing a Vim that supports Python 3

brew install vim

Option 2: Installing [MacVim][]

brew install macvim

Compile YCM.
For Intel and arm64 Macs, the bundled libclang/clangd work:

cd ~/.vim/bundle/YouCompleteMe python3 install.py --all
If you have troubles with finding system frameworks or C++ standard library,
try using the homebrew llvm:

brew install llvm cd ~/.vim/bundle/YouCompleteMe python3 install.py --system-libclang --all

And edit your vimrc to add the following line to use the Homebrew llvm’s
clangd:

viml " Use homebrew's clangd let g:ycm_clangd_binary_path = trim(system('brew --prefix llvm')).'/bin/clangd'
For using an arbitrary LSP server, check the relevant
section

Quick start, installing all completers
