Why do I keep getting "[eslint] Delete `CR` [prettier/prettier]"?

Question

I am using VS Code with Prettier 1.7.2 and ESLint 1.7.0. After every newline I get:

[eslint] Delete `CR` [prettier/prettier]

This is the .eslintrc.json :

{
  "extends": ["airbnb", "plugin:prettier/recommended"],
  "env": {
    "jest": true,
    "browser": true
  },
  "rules": {
    "import/no-extraneous-dependencies": "off",
    "import/prefer-default-export": "off",
    "no-confusing-arrow": "off",
    "linebreak-style": "off",
    "arrow-parens": ["error", "as-needed"],
    "comma-dangle": [
      "error",
      {
        "arrays": "always-multiline",
        "objects": "always-multiline",
        "imports": "always-multiline",
        "exports": "always-multiline",
        "functions": "ignore"
      }
    ],
    "no-plusplus": "off"
  },
  "parser": "babel-eslint",
  "plugins": ["react"],
  "globals": {
    "browser": true,
    "$": true,
    "before": true,
    "document": true
  }
}

The .prettierrc file:

{
  "printWidth": 80,
  "tabWidth": 2,
  "semi": true,
  "singleQuote": true,
  "trailingComma": "es5",
  "bracketSpacing": true,
  "jsxBracketSameLine": false,
}

How can I get rid of this error?

Answer 1

Try setting the "endOfLine":"auto" in your .prettierrc file (inside the object)

Or set

'prettier/prettier': [
  'error',
  {
    'endOfLine': 'auto',
  }
]

inside the rules object of the eslintrc file.

If you are using windows machine endOfLine can be "crlf" basing on your git config.

Answer 2

change this setting on VSCode.

Answer 3

In my windows machine, I solved this by adding the below code snippet in rules object of .eslintrc.js file present in my current project's directory.

    "prettier/prettier": [
      "error",
      {
        "endOfLine": "auto"
      },
    ],

This worked on my Mac as well

Answer 4

in the file .eslintrc.json in side roles add this code it will solve this issue

      "rules": {
    "prettier/prettier": ["error",{
      "endOfLine": "auto"}
    ]

  }

Answer 5

I know this is old but I just encountered the issue in my team (some mac, some linux, some windows , all vscode).

solution was to set the line ending in vscode's settings:

.vscode/settings.json

{
    "files.eol": "\n",
}

https://qvault.io/2020/06/18/how-to-get-consistent-line-breaks-in-vs-code-lf-vs-crlf/

Answer 6

Fixed - My .eslintrc.js looks like this:

module.exports = {
  root: true,
  extends: '@react-native-community',
  rules: {'prettier/prettier': ['error', {endOfLine: 'auto'}]},
};

Answer 7

Solution

git config --global core.autocrlf false

After global configuration, you need to pull the code again.

Root cause of the problem:

The culprit is git , a configuration property of core.autocrlf

For historical reasons, the line breaks of the text file on windows and linux are different.

• Windows At the time of line break, carriage return is used at the same time CR(carriage-return character) and line breaks LF(linefeed character)
• Mac and Linux only use the newline character LF
• Old version of Mac uses carriage return CR

Therefore, there will be incompatibility problems when text files are created and used in different systems.

When I clone code on Windows , autocrlf is true as default and then each line of the file is automatically converted to CRLF . If you do not make any changes to the file, eslint delete CR by pre-commit since git automatically convert CRLF to LF .

Answer 8

Try this. It works for me:

yarn run lint --fix

or

npm run lint -- --fix

Answer 9

Fixed: My eslintrc.js some rule look like this:

rules: {
    'prettier/prettier': ['error', { "endOfLine": "auto"}, { usePrettierrc: true }],  // Use our .prettierrc file as source
    'react/react-in-jsx-scope': 'off',
    'react/prop-types': 'off',
    'simple-import-sort/imports': 'error',
    "simple-import-sort/exports": "error"
}

Answer 10

I am using git+vscode+windows+vue, and after read the eslint document: https://eslint.org/docs/rules/linebreak-style

Finally fix it by:

add *.js text eol=lf to .gitattributes

then run vue-cli-service lint --fix

Answer 11

将此添加到您的.prettierrc文件并打开VSCODE

"endOfLine": "auto"

Answer 12

If the above code is not working for you try these two steps.

1. in the file .eslintrc.json inside roles object add this code it will solve this issue

 "prettier/prettier": ["error",{
      "endOfLine": "auto"}
    ]

2 Change dev server --fix

npm run dev

To

npm run dev --fix

OR

npm run lint -- --fix
yarn run lint -- --fix

Answer 13

Add these below rule in .eslintrc file and then restart your project.

rules: {
    'prettier/prettier': ['error', { "endOfLine": "auto"}, { usePrettierrc: true }],  
}

Answer 14

As you can see add this into.eslintrc works

Answer 15

Check the right-hand side of VS Code's status bar at the bottom where it shows information such as line and column, spaces, text encoding (UTF-8 etc). You should see a Select End Of Line Sequence status display (either LF or CRLF ) that you can click on to change. Make sure you haven't manually changed this to something that conflicts with what you wish Prettier to use.

Answer 16

我升级到“更漂亮”：“^2.2.0”并且错误消失了

Answer 17

In my case I am using windows OS and git code supports in Mac and getting converted to CRLF run below Command in cmd prompt to stop files getting converted to CRLF:

git config --global core.autocrlf input

Checkout the code again and open Visual Studio Code again and run your scripts again. It worked for me.

Answer 18

The best solution is to use .editorconfig . Especially if you are working with a team with different type OS. So disabling prettier in.eslintrc is not a good option at all.

Install.editorconfig from your vscode extension. Create a .editorconfig file in your project root directory and it to your .gitignore file so it won't bother your teammates.

Add this to your .editorconfig file or choose what workflow settings you need from the documentation .

[*]
end_of_line = lf

This will save your file automatically to EOL type lf instead of crlf in windows. Vise versa if using mac. Or depends on the project workflow setup.

The root cause is windows is default to crlf. So every time you try to create a file you will face this prettier Delete 'cr' error.

In Addition

If all the files you got from git contains Delete 'cr' .

1. Delete your project
2. Reinstall your git and choose checkout as-is, commit Unix-style line endings
3. Clone your project from repo again
4. Use the.editorconfig set up above

Answer 19

In the root open the .editorconfig file and change:

end_of_line = lf

to

end_of_line = auto

This should fix it for new files.

Answer 20

There is no need to ignore linter's rule. Just auto-fix it

npm install -g prettier
prettier -w .\webpack.config.js # or other file

Answer 21

I tried everything here and for me, I needed to manage prettier config extension through icon extensions > prettier > small engine > extensions settings > Prettier: End Of Line > set to auto.

After adding these two lines in my settings.json

"eslint.run": "onSave",
"editor.formatOnSave": true,

I was able to use the config below inside .eslintrc.js rule.

"prettier/prettier": ["error", {
    "endOfLine":"auto"
}],

Answer 22

If you need to use with.prettierrc.js:

module.exports = {
    ...[config params],
    endOfLine: 'auto',
};

Note Not in rules or prettier/prettier .

Info here https://prettier.io/docs/en/options.html#end-of-line

Answer 23

上面的所有答案都是正确的，但是当我使用 Windows 并禁用 Prettier ESLint 扩展rvest.vs-code-prettier-eslint ，问题将得到解决。

Answer 24

What worked for me was:

1. Update prettier to version 2.2.1 (latest version at the moment) as Roberto LL suggested. To do it execute

npm update prettier

2. Execute lint fix as Hakan suggested (This will modify all files in the project to convert line ending to LF).

npm run lint -- --fix

It was not necessary to change .eslintrc and .prettierrc files!

Answer 25

I was having the same problem in my nest js app . Adding the below code to .eslintrc.js rules and then running yarn run lint --fix fixed the issue .

'prettier/prettier': [
  'error',
  {
    endOfLine: 'auto',
  },
],

and my .eslintrc.js rules looks something like this..

 rules: {
'@typescript-eslint/interface-name-prefix': 'off',
'@typescript-eslint/explicit-function-return-type': 'off',
'@typescript-eslint/explicit-module-boundary-types': 'off',
'@typescript-eslint/no-explicit-any': 'off',
'prettier/prettier': [
  'error',
  {
    endOfLine: 'auto',
  },
],

},

Answer 26

Solution

1. Disable auto conversion git setting

git --global config core.autocrlf false

2. Remove old cache data

git rm --cached -r .

3. Reset git files

git reset --hard

Answer 27

Error appears when I pull code from git, and this work for me:

STEP 1:

git config --global core.autocrlf false

STEP 2:

• delete your current folder

STEP 3:

• pull code from git again
• try running command again

Answer 28

Its work for me

step-1 React js root directory find .eslintrc file

Step-2 find in .eslintrc

"prettier/prettier": [
  2,
  {
    "printWidth": 100,
    "singleQuote": true,
    "trailingComma": "none",
    "tabWidth": 2
  }
]

replace with

"prettier/prettier": [
  "error",
  {
    "endOfLine": "auto"
  }
]

save file and then run

npm start

Answer 29

edit your .eslintrc.json file and update "prettier/prettier" value shown below.

I face same problem and fixed using below changes. "prettier/prettier": ["error", { "singleQuote": true, "parser": "flow" }],

Answer 30

In the .eslintrc file add the following:

• extends: ['prettier'] and plugins: ['prettier']

• rules: {'prettier/prettier': ['error', {endOfLine: 'auto'}]}

In .prettierrc remove this:

• endOfLine: 'auto'

It works for me.

Answer 31

if you have already checked out the code

git config --global core.autocrlf input 


git rm --cached -r . 


git reset --hard

Answer 32

npm run lint -- --fix

Run this command this worked for me

Answer 33

For those using @vue/prettier there may be a conflict between it and eslint which results in this error. Despite being installed along with vue cli, @vue/prettier was a temporary solution until prettier accepted vue natively and that has already been done . The problem can be solved by switching to just 'prettier'

Answer 34

executing eslint for linting and fixing solved my issue.

eslint. --ext.vue,.js,.jsx,.cjs,.mjs,.ts,.tsx,.cts,.mts --fix --ignore-path.gitignore

or if you have lint script: npm run lint

Answer 35

You need add rules the file.eslintrc

"extends": ["plugin:prettier/recommended"],
"plugins": ["prettier"],
"rules": {
 "prettier/prettier": ["error"],
 "@typescript-eslint/no-unsafe-call": "off",
 "@typescript-eslint/unbound-method": "off",
 "@typescript-eslint/no-explicit-any": "off",
 "@typescript-eslint/no-unsafe-member-access": "off",
 "@typescript-eslint/no-unsafe-assignment": "off",
 "@typescript-eslint/no-empty-function": "off",
 "@angular-eslint/no-empty-lifecycle-method": "off",
 "@typescript-eslint/no-unused-vars": ["off"],
 "@typescript-eslint/require-await": "off",
 "@typescript-eslint/ban-types": "off"
}

Answer 36

Delete this line from the file.prettierrc

 "endOfLine": "crlf"

Answer 37

Change file type from tsx -> ts, jsx -> js

You can get this error if you are working on .tsx or .jsx file and you are just exporting styles etc and not jsx. In this case the error is solved by changing the file type to .ts or .js
