eslintIntegration. Cannot read property 'sync' of undefined

[dcorb]

It's the first time I'm trying to set it up, so I might have skipped something obvious, but can't figure it out.

After CMD + Shift + P -> Format Document , it shows in the Output tab:

Cannot read property 'sync' of undefined

I just installed the extension today, version 0.24 Settings of the plugin: { "prettier.eslintIntegration": true }

prettier 1.6.1 eslint 4.8.0 . (installed globally)

.eslintrc content is:

{
    "extends": [
        "plugin:react/recommended"
    ],
    "plugins": [ "react" ],
    "parserOptions": {
        "ecmaVersion": 8,
        "sourceType": "module",
        "ecmaFeatures": {
            "impliedStrict": true,
            "jsx": true
        }
    }
}

in package.json of the project we have "prettier-eslint": "^6.4.1", (although prettier is installed globally)

I also enabled VS Code DevTools, nothing there

Prettier 1.7.0 has the sync() function that is missing here (1.6.1)

https://github.com/prettier/prettier/commit/088aa71b07bc25bc3640b1e188ec906ef6d17b1b

[CiGit]

What I read here is not missing sync function but missing member. Could you find a stack trace?

[azz]

https://github.com/prettier/prettier-eslint/releases/tag/v6.4.3

prettier-eslint bundles in prettier and 1.6.0 of prettier was added in 6.4.3. Upgrading prettier-eslint should fix the problem.

[CiGit]

Sorry, forgot to mention. We don't use user's installed version. https://github.com/prettier/prettier-vscode/blob/master/src/PrettierEditProvider.ts#L125

We bundle prettier-eslint@8.2

[azz]

Ah, didn't know that. What are the possible ways it is resolving prettier <1.6?

[CiGit]

It's the one installed locally. This is the case, but we use resolveConfig (async version) from our bundled prettier

In

Cannot read property 'sync' of undefined

It's not sync which makes me think of a problem, but undefined

The only .sync in our src is here: https://github.com/prettier/prettier-vscode/blob/master/src/requirePkg.ts#L14 This line shouldn't be hit with eslint.

Thanks for the help, I updated prettier globally to latest, didn't work Then, update prettier-eslint, I got 6.4.3 version .. and after restarting VSCode it worked ! Thanks for the fast replies guys, appreciated!

[CiGit]

So the fix is "restart vscode" ?

Out of curiosity, have you restarted vscode in those last 2 days? (since you installed last release )

[nealoke]

@CiGit the fix in my case was removing prettier from my node_modules, adjusting my package.json file to use the latest version of prettier (1.7.4) and hitting npm install. Ofcourse restart vscode after 👍

[CiGit]

So prettier@1.6.1 + eslintIntegration fails?

[CiGit]

Just tried and it works on my machine :-)

What doesn't is with prettier 1.5 ...

prettier.resolveConfig is not a function

in prettier-eslint

[nealoke]

@CiGit I guess 👍

Suddenly I got this bug, before that I didn't update or install anything.

@CiGit yes, I have been restarting every time I was changing something. But when I upgraded prettier and prettier-eslint, I noticed also a message from VSCODE: "installation appears to be corrupt", https://code.visualstudio.com/docs/supporting/faq#_installation-appears-to-be-corrupt so I updated to the last VSCode version 1.16.1, (my previous installation was 1 month old) . And then things worked. Sorry it's not very helpful to pinpoint the problem. But I still think the issue was with outdated versions of prettier and prettier-eslint

[nealoke]

@nguyennb9 the extensions auto update so it can be that the extension requires 1.7.x or that in your vscode workspace have a prettier: 1.7.x installed

[nguyennb9]

@nealoke My team using prettier version 1.1.0, I think I need downgrade this extension to keep it work with prettier 1.1.0

[seancheung]

npm update -D prettier

ctrl+shift+p -> Reload Window

This should work

[KATT]

I only had prettier-eslint-cli in my package.json, this solved it for me:

npm update -D prettier-eslint-cli

[tizmagik]

I got this today, @seancheung workaround worked for me 👍

[raviteja83]

Try adding this to workspace settings. { "prettier.eslintIntegration": false} This worked for me

[CiGit]

This is definitely a trouble with prettier-eslint.
