Question

I am facing issue when I am trying to run tslint from Angular Cli.

Failed to load E:\Projects\lsp-ui\node_modules\ng2-slimscroll\tslint.json: Could not find custom rule directory: E:\Projects\lsp-ui\node_modules\ng2-slimscroll\node_modules\codelyzer

You are missing codelyzer in your node_modules. Did you install the dependencies (with npm install)? – Tablet

Yes i did. But still its is giving same error – Rub

Try to check the versions of nodeJS, angular / angular-cli and VSC. If anything try to uninstall and re-install with all the latest versions. – Apical

Answer 1

Run npm install or npm install codelyzer first.

Also check the file path of tsconfig.json in the Angular Cli configuration lint section, the configuration of rules directory in tslint.json, such as:

"rulesDirectory": [
        "../node_modules/codelyzer"
    ]

I'm not sure about this. Angular is supposed to install codelyzer: the "ng new" command is supposed to do all the installs – Apical

Answer 2

Here is official guide for you.

Codelyzer should work out of the box with Atom but for VSCode you will have to open Code > Preferences > User Settings, and enter the following config:

{ "tslint.rulesDirectory": "./node_modules/codelyzer",
"typescript.tsdk": "node_modules/typescript/lib" }
