Error: Cannot find module 'svelte-prettier-plugin'

[Benjamin Knight]

I've just installed this plugin using npm install --save-dev prettier-plugin-tailwind. I'm not using Svelte at all but when I run prettier I get the following error:

▶ npm run format

> vietnamcoracle-next@ format /Users/ben/Code/vietnamcoracle-next
> prettier --write "src/**/*.{js,jsx}"

internal/modules/cjs/loader.js:883
  throw err;

Downgrading to v2.1.9 solved the issue for me.

@benknight I tried using npm and yarn to format but haven't been able to reproduce this error.

If it still persists, perhaps opening a reproduction repo will help.

[Ari Seyhun]

@benknight @adiun it would be helpful if you could provide the version of NPM/Yarn you are using and the version of prettier.

I just encountered the same issue using npm v6.14.8 and Prettier v2.2.1. Neither svelte-prettier-plugin or prettier-plugin-svelte can be found in my package-lock.json file.

[Mykhaylo Ryechkin]

Looks like I was having this issue as well, was getting the Prettier cannot format [file].js error - looking for solutions led me to this issue.

Downgrading to 2.1.9 as @benknight suggested worked for me 👍

[Ari Seyhun]

In v2.2.8 I've removed svelte support. I'm not sure on how to fix this so for now I've just removed the issue and it should be working again now.
