I have a very strange issue with Eslint and Angular. Every time I run ng lint I get errors such as:
An unhandled exception occurred: Cannot read config file: [COMPLETELY_DIFFERENT_PROJECT_PATH]\node_modules\[email protected] Error: "prettier/@typescript-eslint" has been merged into "prettier" in eslint-config-prettier 8.0.0. See: https://github.com/prettier/eslint-config-prettier/blob/main/CHANGELOG.md#version-800-2021-02-21
Referenced from: [COMPLETELY_DIFFERENT_PROJECT_PATH]\node_modules@nestjs\axios.eslintrc.js See "[USER]\AppData\Local\Temp\ng-H0X9RR\angular-errors.log" for further details.
Note that these errors occur in a completely different project and a completely different folder than the project I'm running the ng lint command from.
To verify this issue I created a completely new and fresh Angular project using
ng new
And then add eslint schematics using
ng add @angular-eslint/schematics
This generates the following project files:
.eslintrc.json

But even for a completely clean project running ng lint still gives me errors about files that are in a completely different folder than the project I'm running it from. I already searched high and low for a solution but I can't seem to find any solution to this.
What I also find strange is that the eslint extension in VSCode for detecting linting issues while you're programming does work: https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint
I'm completely stumped by this. Is there anyone who can help me?
CodePudding user response：
Try to specify the working directory eslint --ext .js,.ts . the . or, ng lint --files=src/**/*.ts.
You can add this to package.json as: lint:eslint --ext .js,.ts . and run npm run lint
