[nevertoday]

我反复安装多次了， 其他貌似都欧克， 但这个总提示， 也无法 在保存的时候，格式化代码， 请问 how to fixed this .
thks .

[CharlesChiuGit]

What filetype are u editting? Does it have a corresponding lsp?
If u have installed the corresponding lsp, please check :LspInfo to check if the lsp is activated.

[nevertoday]

I just edit shell files and html files with .html and .sh extension files .

[CharlesChiuGit]

So bashls and efm are both running, which is a good sign.
What version of nvim and os are u currently running?

[CharlesChiuGit]

Nvim 0.8.0 looks fine.
Also please delete the help page. Help pages are suppost to help figure things out, not something u should post.

[nevertoday]

so so so strange 。。。

[CharlesChiuGit]

What kind of sh file are u editing? bashrc or XXX.sh?

[nevertoday]

XXX.sh

[nevertoday]

and 1.html

[CharlesChiuGit]

Can close and re-open the same file and try to save again?
Sometimes it's the lsp haven't fully started, I myself sometimes go the same error too. Re-open the files and the error should go away.

my error:

[nevertoday]

Can close and re-open the same file
I have try this dozens times

[CharlesChiuGit]

I believe it's an upstream issue, maybe we need to wait for bash-lsp or related plugins to update.

[CharlesChiuGit]

@nevertoday so did u have the similar error like mine in the sceenshot?

[nevertoday]

Spawning language server with cmd: efm-langserver failed. The language server is either not installed, missing from PATH, or not executable.

[nevertoday]

[CharlesChiuGit]

Have you tried :LspStart when u meet similar error? I can format my shell scripts after running :LspStart when encounter such error.

[nevertoday]

[CharlesChiuGit]

For html files, you have to install the lsp manually.
As u can see in this

nvimdots/lua/modules/completion/lsp.lua

Line 66 in 61fe5b7

for _, server in ipairs(mason_lsp.get_installed_servers()) do

and this section

nvimdots/lua/modules/completion/lsp.lua

Lines 212 to 224 in 61fe5b7

	nvim_lsp.html.setup({
	cmd = { "html-languageserver", "--stdio" },
	filetypes = { "html" },
	init_options = {
	configurationSection = { "html", "css", "javascript" },
	embeddedLanguages = { css = true, javascript = true },
	},
	settings = {},
	single_file_support = true,
	flags = { debounce_text_changes = 500 },
	capabilities = capabilities,
	on_attach = custom_attach,
	})

Html lsp are not install automatically, install it via:

npm i -g vscode-langservers-extracted

ref: https://github.com/hrsh7th/vscode-langservers-extracted

[CharlesChiuGit]

Also u might need to change the html's config. Please take this as refernce.

[nevertoday]

After this npm i -g vscode-langservers-extracted

same error appear

[nevertoday]

macos system version 13.0

[CharlesChiuGit]

Hmmm, weird...
I'm not a html coder, so i can't test it for you. But in

nvimdots/lua/modules/completion/lsp.lua

Line 277 in 61fe5b7

html = { formatter = prettier },

efm is supposed to use prettier to format the html code.

Sorry i can't help u further...

[nevertoday]

i can use = g to format all code

[nevertoday]

xxx.sh file same error message

[nevertoday]

markdown files same error

[nevertoday]

[CharlesChiuGit]

Maybe wait for the repo author to help u

[nevertoday]

@nevertoday Formatting support for shell and markdown files is provided by prettier. Have you used a package manager (e.g. brew install prettier) or Mason to install the prettier executable itself? efm works well on my machine running MacOS 12.6.

After installing prettier using Mason, you will see:

Detail:

nvimdots/lua/modules/completion/lsp.lua

Line 277 in 61fe5b7

html = { formatter = prettier },

nvimdots/lua/modules/completion/lsp.lua

Line 281 in 61fe5b7

markdown = { formatter = prettier },

Looks like the problem has been resolved. Feel free to reopen it if you encounter other related issues 👍

[nevertoday]

Mason

u mean i should change lsp to Mason ??

[CharlesChiuGit]

Mason and lsp are not the same thing, please do some research first.

[Jint-lzxy]

Mason

u mean i should change lsp to Mason ??

The short answer is:
You should use Mason to install the corresponding code formatter. In this case, prettier.

Long answer:
Mason is not a language server. The working principle behind this is Mason is a package manager written for Neovim (similar to Homebrew), while efm is a General Purpose Language Server (lsp), which only runs the executable files that the user has installed. In order to format the code, you need to install the corresponding program for efm to use, and in this case, prettier. You may use any global package manager like brew install prettier or Mason to install the formatter.

Does this sound a bit clearer?

[nevertoday]

thanks all handsome and pretty

I finally decide use lunarvim

[nevertoday]

I really don't know how to fix this , too hard to get the right way .

[ayamir]

You just need to install lsp server like what I wrote in wiki.
If you want to format html file on save, you need to make sure prettier can be found in your PATH. You can execute :MasonInstall prettier in nvim to install it easily.
And all problems will be solved.

[CharlesChiuGit]

@nevertoday I once tried Lunarvim, but it also has it's own issue. One day u will still need to know how to fix bugs like this.
The donw side of a highly pre-config nvimdot is that u can't be sure about wether the bug is from lunarvim, plugins or nvim itself.

[nevertoday]

brew install efm-langserver

after install this, all things work fine.

maybe this is the right answer.

[CharlesChiuGit]

Seems like it's stated in the wiki

For efm-langserver, you need to install itself and format/lint tools manually.

or

:MasonInstall efm

[nevertoday]

:MasonInstall efm

failed :

go failed with exit code - and signal -. go is not executable

[CharlesChiuGit]

In mason.nvim's requirements

Note that mason.nvim will regularly shell out to external package managers, such as cargo and npm. Depending on your personal usage, some of these will also need to be installed. Refer to :checkhealth mason for a full list.

And efm-lsp is written in go, so u need to install go if u want to use mason to install go stuffs.

[nevertoday]

npm config set perfix ~/.local

this works for me

then markdown no error appear anymore .

[CharlesChiuGit]

good, as u mentioned earlier.
u manually install efm via brew, which will also works.

[nevertoday]

thank u so much , and I have many bulk edit skill need to learn.
long time use vscode , now come back to vim , exceting
