Getting `Cannot read property 'prettier' of undefined` message about prettier-vscode

[CiGit]

I've seen it, the fix is here #74
As a current workaround, be sure your package.json contains dependencies and devDependencies. They may be empty {}

I got this exact same problem after updating.

EDIT:

I got it to work by adding "prettier": "^1.1.10" to devDependencies and do npm install

[mogarick]

Hi @CiGit,
Mi package.json has dependencies and devDependencies objects with many properties.

[mogarick]

I've also checked the prettier package.json included with the extension and it's not empty either.

[CiGit]

Can you also check in parent package.json if any?

[jtulk]

I'm having the same problem after the update.

[CiGit]

Also no package.json without dependencies and devDependencies?
on the path from / to your file ?

[mogarick]

@CiGit the parent package.json also appears OK, with the dependencies properly declared (esbenp.prettier-vscode-0.13.0/package.json):

[CiGit]

I was meaning in package.json located along the path

/
  package.json
  a/
    package.json
    b/
     .....
        workspace
          package.json
          dir/
            fileToFormat.js

This are the place where it could occur.

[mogarick]

@CiGit There only 1 package.json in my project tree is a CRA(create-react-app) and goes as follow:

/ProjectRoot
  /node_modules
  /src
    myfileToFormat.js
  package.json (My project. No empty deps objects)

the only additional package.json files are the ones related to the proper project dependencies but they're in the node_modules directory which is not along my src files path.

Is it more clear now?

[CiGit]

I still don't know where it can come from. Is it possible for you to debug it? I won't ask your entire file system 😈

[jtulk]

Like @JesusIslam - things resolved for me when installing Prettier locally into the repo. So it seems like VSCode might not be checking for a globally installed copy and defaulting to that?

[didasy]

@jtulk #67 seems right, it needs to be explicitly installed now.

[mogarick]

Indeed!
I installed prettier as devDependency and the problem was solved.
It would be excellent to add a note in the readme.md that prettier needs to be available as a dependency for the project or at least installed as a global (I didn't check if it works when prettier is installed as global module).

[didasy]

@mogarick it didn't work as a global for me at least.

[CiGit]

Just published 0.13.1 with a patch that should correct this issue. At least what I could reproduce.
@esbenp I finally found out how to publish ... was really tough

[jtulk]

@CiGit - Does the patch require a local install or will it work off a global install now? I'll be happy to do a PR to annotate the docs if it requires a local copy...

[CiGit]

It loads prettier packed with the extension if there is no local install. It doesn't use your globally installed prettier.
PR welcome to update https://github.com/esbenp/prettier-vscode#prettier-resolution ;-)

[tizmagik]

I just hit this today VSCode Version 1.16.1, prettier-vscode 0.24.0 and had to install prettier locally to fix it (npm i -D prettier) it was working fine without that previously...

[CiGit]

@tizmagik How was your setup before you installed prettier? Stack trace?

[tizmagik]

Where would the stacktrace be? All I saw was the Cannot read property 'prettier' of undefined message in the output tab

[CiGit]

Damn, I also forgot some informations here. I meant debug it :-)
clone it, npm i, open it in vscode and F5 (Start debugging)
