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.
