Couldn't resolve parser "postcss" when updated prettier to v2.0.4

[etylsarin]

I use prettier-stylelint to let prettier formart my scss files using my stylelint rules. I have a problem since I upgraded from v 1.19.1 to 2.0.4 I have found that there was a similar issue with prettier-atom while ago: https://github.com/prettier/prettier-atom/issues/388

Environments:

• Prettier Version: 2.0.4
• Running Prettier via: prettier-stylelint
• Runtime: Node.js v10.18
• Operating System: macOS Catalina Steps to reproduce:

prettier-stylelint --write --quiet 'src/**/*.{css,scss}'"

Expected behavior: to pass all the formatting without throwing an error

Actual behavior: I got an error: prettier-stylelint [ERROR]: There was an error formatting "src/index.scss"

Error: Couldn't resolve parser "postcss" at resolveParser (/Users/myname/repos/project/node_modules/prettier/index.js:11341:15) at normalize$1 (/Users/myname/repos/project/node_modules/prettier/index.js:11436:18) at formatWithCursor (/Users/myname/repos/project/node_modules/prettier/index.js:15032:12) at args (/Users/myname/repos/project/node_modules/prettier/index.js:50675:12) at Object.format (/Users/myname/repos/project/node_modules/prettier/index.js:50695:12) at resolveConfig.then/Users/myname/repos/project/node_modules/prettier-stylelint/src/index.js:129:30)

A temporary workaround until prettier-stylelint is fixed:

1. In project root, create patches/prettier-stylelint+0.4.2.patch with contents:

diff --git a/node_modules/prettier-stylelint/src/index.js b/node_modules/prettier-stylelint/src/index.js
index 124c00d..a6f12ec 100644
--- a/node_modules/prettier-stylelint/src/index.js
+++ b/node_modules/prettier-stylelint/src/index.js
@@ -60,7 +60,7 @@ resolveConfig.resolve = (stylelintConfig, prettierOptions = {}) => {
             prettierOptions.tabWidth = indentation;
         }
     }
-    prettierOptions.parser = 'postcss';
+    prettierOptions.parser = 'css';
     debug('prettier %O', prettierOptions);
     debug('linter %O', stylelintConfig);

2. In package.json, add to scripts:

  "scripts": {
    "postinstall": "patch-package"

3. yarn add --dev patch-package
4. yarn install will now patch the package.

We faced the same issue after bumping up our prettier to version 2.3.2, prettier-stylelint --write threw the same error.

Although I don't even understand why but using stylelint-prettier seems to work for us 😂 We installed the package:

npm install --save-dev stylelint-prettier

Then just added this to our .stylelintrc.js

{
  "plugins": ["stylelint-prettier"],
  "rules": {
    "prettier/prettier": true
  }
}

I'd love to know if anyone tried the same and success and can explain what happens under the hood 😄

Will this be fixed or is it safe to consider this package to be abandoned?
