Error after updating eslint to 8.1.0

[1v3n]

Hey,

once I update eslint from 7.32.0 to 8.1.0. I see an error on my command line when I run prettier-eslint:

Scripts:

"prettier:watch": "onchange \"**/*.+(js|jsx|json|scss|css)\" -- prettier-eslint --write $PWD/{{changed}}",
"prettier:format": "prettier-eslint --write \"src/**/*.+(js|jsx|json|scss|css)\"",

My config:

• prettier-eslint-cli version: 5.0.1
• prettier version: 2.4.1
• eslint version: 8.1.0

prettier-eslint shows error:

prettier-eslint [ERROR]: There was trouble creating the ESLint CLIEngine.

Supporting prettier-eslint, prettier, and eslint later than v9.0.2, v1.19.1, and v5.16.0, respectively, is #304. 😕

https://eslint.org/docs/8.0.0/user-guide/migrating-to-8.0.0#remove-cliengine seems to be useful

any updates?

I am running into this issue as well when updating to eslint v8.13.0. Any updates or should I wait on updating eslint?

[idahogurl]

@haase1020 Support for ESLint 8 is coming (see prettier/prettier-eslint#696). However there was an issue with the publishing process and it didn't push out a new version. In short, do not update to ESLint 8 just yet.

@idahogurl Thanks for your work on this. I'm running the following (all the latest versions, AFAICT):

"eslint": "8.13.0",
"prettier": "2.6.2",
"prettier-eslint": "14.0.0",
"prettier-eslint-cli": "5.0.1",

... and yet I'm still seeing:

$ ./node_modules/.bin/prettier-eslint file.js

[georgecrawford]

Since prettier/prettier-eslint#696 is merged and prettier-eslint supports ESLint v8, what are the chances of this project upgrading eslint and prettier-eslint?
