What is the current/expected behavior?

What version of vim-prettier are you using - (output of :PrettierVersion) ? 1.0.0-beta

What version of prettier are you using - (output of :PrettierCliVersion) ? 2.1.2

What is your prettier executable path - (output of :PrettierCliPath) ? Users/dangvanthanh/.config/nvim/plugged/vim-prettier/node_modules/.bin/prettier

Hi, I'm receiving the same error.

.vimrc

call plug#begin('~/.vim/plugged')

Plug 'prettier/vim-prettier', { 'do' : 'yarn install' }

Same here

call plug#begin('~/.vim/plugged')
Plug 'prettier/vim-prettier', { 'do': 'yarn install' }
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
call plug#end()

I had the same issue with old versions. It got resolved when I removed .prettierrc After upgrading to the latest, even without a config file, I get this error leaving me unable to use the plugins.

[zirho]

I found the workaround.

put this in vim config

let g:prettier#config#single_quote = 'true'
let g:prettier#config#trailing_comma = 'all'

[dangvanthanh]

I found the workaround.

put this in vim config

let g:prettier#config#single_quote = 'true'
let g:prettier#config#trailing_comma = 'all'

Thanks @zirho

I was removed

let g:prettier#config#parser = 'babylon'

then put your config. It's working for me.

[hkennyv]

i can confirm that @zirho 's solution works for me!

[sohel-sheikh]

I too confirm @zirho 's solution worked for me!

[zirho]

this might be related to error [error] Invalid --trailing-comma value. Expected "all", "none", "php5" or "php7.2", but received "es5".

[zirho]

possibly related to NVM and the default version of node being set in the system. Prettier is being run with the default version and that could lead to this error.

[smithbm2316]

I can confirm that @zirho's solution also worked for me :), really enjoying this plugin, thank you to the devs for creating this it is wonderful to get Prettier support inside of Neovim!

[mikepqr]

FWIW and in case it's a clue for the root cause, I only needed one line:

let g:prettier#config#trailing_comma = 'all'

from @zirho's solution to get rid of Prettier: failed to parse buffer. That was with vim-prettier 1.0.0-beta and prettier installed by the plugin at version 2.0.4.

[michaeljones]

It is potentially an issue with the php plugin, though I've no idea. Maybe it is overwriting the available trailing comma options? I'm getting the same issue on my Mac setup. If I remove the plugins from the package.json file (as I don't need any of them) then delete node_modules and yarn install again then it starts working.

I would also deeply appreciate some way of getting more information out of prettier when seeing the "failed to parse buffer" error. I didn't see any option but is there some kind of verbose logging mode to help debug this? I ended up adding echom join(a:errors, "\n") to the onError function in job/runner.vim.

[michaeljones]

Possibly also because the package.json specifies 0.10.2 for the php plugin and that was released back in February 2019. There have been a number of fixes (probably including this) since then.

It might make sense to specify a much looser constraint.

[jgreens]

I found the workaround.

put this in vim config

let g:prettier#config#single_quote = 'true'
let g:prettier#config#trailing_comma = 'all'

Thank you so much – this finally fixed my issue!

[gadkadosh]

This is indeed related to prettier-php version being too old. The problem was fixed: https://github.com/prettier/plugin-php/issues/964 Updating to a newer version than plugin-php 0.11.1 should solve the problem.

Not fixed

[dvbsknd]

possibly related to NVM and the default version of node being set in the system. Prettier is being run with the default version and that could lead to this error.

I stumbled across this issue after searching for the Prettier: failed to parse buffer error and my issue was indeed my Node version. My shell was running version 8 via nvm rather than my default version 16 when I started vim. After exiting, switching and trying again it worked.

[aaaaargZombies]

I found the workaround.

put this in vim config

let g:prettier#config#single_quote = 'true'
let g:prettier#config#trailing_comma = 'all'

This works for me but I want to run prettier with the defaults so it's not an ideal solution.

What's the best way to check which version of node vim-prettier is running and is there a way to configure a version for vim-prettier? NVM is currently set to current LTS v14.17.4

[jikkujose]

This is causing me issues for me now :(

Solutions I tried:

• I tried to use the prettier config mentioned (though I don't see how it affects the parser!)

My versions:

1. PrettierVersion: 1.0.0-beta
2. PrettierCliPath: ~/.vim/plugged/vim-prettier/node_modules/.bin/prettier
3. PrettierCli: [error] No parser and no file path given, couldn't infer a parser.^@

[nguyenvukhang]

In my experience this issue is caused by me renaming the root directory of a directory containing node packages.

My fix has been to delete the node_modules folder and run npm or yarn to refresh it:

rm -rf node_modules
yarn

let g:prettier#config#trailing_comma = 'all'

I tried this but it did not work for me on my _vimrc file on windows, surprisingly enough :Prettier or my map <Leader><Leader>p works just fine and .ts/tsx files work just fine on save!

autocmd BufWritePre *.js,*.jsx,*.mjs,*.ts,*.tsx,*.css,*.less,*.scss,*.json,*.graphql,*.md,*.vue,*.svelte,*.yaml,*.html PrettierAsync

I don't face this issue on my linux machine however
