3. Install CMake, Vim and Python

4. Install go, node and npm

5. Compile YCM supporting all language

   cd YouCompleteMe
   python install.py --all --verbose

   对单个语言的编译请看这里

各语言编译

python

cd %USERPROFILE%\vimfiles\plugged\YouCompleteMe
python install.py --verbose

C/C++

Compiling YCM with semantic support for C-family languages through clangd:

cd %USERPROFILE%\vimfiles\plugged\YouCompleteMe
python install.py --clangd-completer --verbose

Compiling YCM without semantic support for C-family languages:

cd %USERPROFILE%\vimfiles\plugged\YouCompleteMe
python install.py -clang-completer --verbose

Others

The following additional language support options are available:

• C# support: add --cs-completer when calling install.py. Be sure that the build utility msbuild is in your PATH.
• Go support: install Go and add --go-completer when calling install.py.
• JavaScript and TypeScript support: install Node.js 18+ and npm and add --ts-completer when calling install.py.
• Rust support: add --rust-completer when calling install.py.
• Java support: install JDK 17 and add --java-completer when calling install.py.

You can specify the Microsoft Visual C++ (MSVC) version using the --msvc option. YCM officially supports MSVC 15 (2017), MSVC 16 (Visual Studio 2019) and MSVC 17 (Visual Studio 17 2022).

  FileNotFoundError: Could not find a valid MSVC version.
  

  解决方案:

  指定 msvc的版本, 如: python install.py --all --msvc=17 --verbose, 其中msvc版本可以是17, 16, 15中的一个
