3. QA

1. no matching host key type found. Their offer: ssh-rsa

# ssh version
[23:30:46] ❯ ssh -V
OpenSSH_8.9p1 Ubuntu-3ubuntu0.1, OpenSSL 3.0.2 15 Mar 2022

# Solution
## add the follwoing to /etc/ssh/sshd_config
Include /etc/ssh/sshd_config.d/*.conf

PubkeyAcceptedKeyTypes +ssh-rsa
HostKeyAlgorithms +ssh-rsa

## update ~/.ssh/config
Host xxxx
  User guanzenghui
  PubkeyAcceptedKeyTypes +ssh-rsa
  HostKeyAlgorithms +ssh-rsa

## gen pub key
ssh-keygen -t rsa

2. Mason or treesitter is slow

search keyword speed in repo

-- lua/modules/editor/treesitter.lua
require("nvim-treesitter.install").command_extra_args = {
	curl = { "--proxy", "http://127.0.0.1:7890" },
}

....

-- lua/modules/completion/lsp.lua
mason.setup({
	max_concurrent_installers = 30,
	-- speed
	github = {
		download_url_template = "https://ghproxy.com/https://github.com/%s/releases/download/%s/%s",
	},
})
....

-- lua/modules/completion/lsp.lua
mason_lspconfig.setup({
	-- speed
	github = {
		download_url_template = "https://ghproxy.com/https://github.com/%s/releases/download/%s/%s",
	},
	automatic_installation = true,
})
...

3. pynvim timeout

# ERROR

ERROR HTTP request failed: error: curl error with https://pypi.python.org/pypi/pynvim/json: 143

# fix:
pip3 uninstall neovim
pip3 uninstall pynvim
pip3 install pynvim
It would be good if the error messages mentioned https://github.com/neovim/neovim/wiki/Following-HEAD#20181118 though.

4. LANG warning

6. nvim-treesitter 编译失败

报错

src/scanner.c:446:5: error: ‘for’ loop initial declarations are only allowed in C99 mode

解决

- 升级 gcc
- 以下任意配置（https://github.com/double12gzh/nvimdots/blob/main/lua/modules/configs/editor/treesitter.lua#L58）
    require("nvim-treesitter.install").compilers = { "clang++" }
    -- require("nvim-treesitter.install").compilers = { "/usr/bin/clang" }
    -- require("nvim-treesitter.install").compilers = { "/usr/bin/c99" }
    -- require("nvim-treesitter.install").compilers = { "gcc" }
