在 windows 平台上为 neovim 添加 python 支持
1. 在 windows 平台上为 neovim 添加 python3 支持
运行
checkhealth
检查支持：
## Python 3 provider (optional)
- WARNING: No Python executable found that can `import neovim`. Using the first available executable for diagnostics.
- WARNING: Could not load Python 3:
python3 not found in search path or not executable.
python3.10 not found in search path or not executable.
python3.9 not found in search path or not executable.
python3.8 not found in search path or not executable.
python3.7 not found in search path or not executable.
python not found in search path or not executable.
- ADVICE:
- See :help |provider-python| for more information.
- You may disable this provider (and warning) by adding `let g:loaded_python3_provider = 0` to your init.vim
- INFO: Executable: Not found说明在 windows 中缺少 python 支持
1. 安装 python
利用 Microsoft Store 可以快捷下载 python 运行环境：
在商店中搜索，或者在终端中输入
python
即可可安装
python
。
安装之后通过这篇文章中的步骤找到
python
路径：
然后将
python
安装位置添加到
Path
系统环境变量中。
2. 为 neovim 添加 python 支持
在终端中执行如下命令：
python3 -m pip install --user --upgrade pynvim需要注意的是原本的
neovim
包被更名为
python
，所以在网上的文章中安装
neovim
包的需要注意。
说明：
执行
pip3 list
查看
pynvim
包是否安装成功：
Package Version
-------- -------
greenlet 2.0.2
msgpack 1.0.5
neovim 0.3.1
pip 23.0.1
pynvim 0.4.3如此则安装成功。
3. 设置 PYTHON PROVIDER
上述工作完成之后还需设置
g:python3_host_prog
变量才能完成 python 对 neovim 的支持，在 neovim 的配置文件中添加下列语句：
let g:python3_host_prog = '/path/to/python3'其中的
'/path/to/python3'
就是
python
的路径，注意路径中一定要带上
python3
。
重启 nvim 再次
checkhealth
检查：

- OK: Latest pynvim is installed.如果不想添加 python 支持，又想让
checkhealth
不检查，只要把把对应模块的 prog＝0就不会检测了。
