Vscode-eslint: [object Object]: ESLint configuration is invalid: - Unexpected top-level property "ecmaFeatures".

[XaveScor]

eslint version is 4.1.1
I have valid config and can run eslint from terminal. My config: https://gist.github.com/XaveScor/90a24430aeac9b6c7b4241e27647c7a8
Error in subject

I am getting the exact same error, even though I do not have the emcaFeatures set in my config file.

Same Problem here

[sosspyker]

I have a typescript project with:
default tsconfig.json file - no references to eslint.
package.json file: No reference to eslint - only dependency is the typescript package.
I do not have .eslintrc.json or eslintDefaults.json files in my typescript project.

However I did install npm install -g eslint when VSCode started complaining about eslint with install suggestion.
For some reason the ESLint server is running for my project - not sure why??
The output tab in ESLint terminal window shows the following:

[Info - 10:08:30 AM] ESLint server is running.
[Info - 10:08:31 AM] ESLint library loaded from: C:\Users[currentuser]\AppData\Roaming\npm\node_modules\eslint\lib\api.js

Having same exact error every time I run below from terminal:
node myJavascript.js

I found error. plugin tries open config from my home directory. I deleted it and eslint works now. Please add logs about some events.

I was have identical problems, and uninstalling the prettier extension made everything better. I also uninstalled / reinstalled eslint @ v1.2.11 and that is fine. Prettier seemed to be the issue in my case, if any of you have that installed as well.

Starting in 4.0.0, ESLint has been throwing a fatal error when encountering unexpected config file properties, including ecmaFeatures. However, many old configs still have the top-level ecmaFeatures option, which has had no effect since ESLint 1.x. This commit updates ESLint to emit a warning when it encounters a config with ecmaFeatures, rather than throwing an error.

will be fixed in [email protected].

as a workaround, you should check ecmaFeatures in your eslint config, and put it in the right place.

I will close the issue then. Please ping if you disagree.

And thanks for the investigation.
