TSLint works on the command line - gulp-tslint returns TypeError: Cannot read property 'getFullWidth' of undefined

[Chowarmaan]

In trying to get this setup, I am getting an error in gulp-tslint, that I do not get using tslint on the command line.

This is the sub job that runs the Typescript compile and TSLint

module.exports = function (gulp, PlugIns, Settings) {
return function () {
    gulp.src(['./app/Modules/**/*.tsx'])
        .pipe(PlugIns.plumber())
        .pipe(PlugIns.debug())
        .pipe(PlugIns.typescript())
        .pipe(PlugIns.tslint( {
            configuration: {
                rules: {
                    "class-name": true,
                    "curly": true,
                    "eofline": true,
                    "indent": [
                        true,
                        "tabs"
                    ],
                }
            }
        }))
        .pipe(PlugIns.tslint.report("stylish"))
        .pipe(gulp.dest(Settings.Destination.TSCompiled))
        ;
    }
};

My Test file that should have errors

class Greeter {
    constructor(public greeting) { }
    greet() {
        return "<h2>" + this.greeting + "</h2>";
    }
    nogreet()
    {
return 'Not ' + this.greeting;
}
};

var greeter = new Greeter("Hello, world!");

gulp-tslint error generated when running gulp:

However, running the tslint from the command line (in the same directory as gulp), the coding issues are returned.

Can you post the version of tslint at ~\Development\node_modules\tslint\ and the version of TypeScript used (perhaps located in ~\Development\node_modules\typescript)? Usually this kind of error happens due to a tslint and TypeScript version mismatch. Try to update them to the latest versions.

├─┬ tslint@3.2.1 │ ├── glob@6.0.4 │ ├─┬ optimist@0.6.1 │ │ ├── minimist@0.0.10 │ │ └── wordwrap@0.0.2 │ └── underscore.string@3.1.1 └── typescript@1.7.5

These are local to the project.

Can you post the output of tslint -v? Note that running tslint from the command line may use a different version than what is under node_modules of the current directory.

For example:

nawi ~/dev/gulp-tslint cat node_modules/tslint/package.json | grep version 
  "version": "3.2.1"
nawi ~/dev/gulp-tslint tslint -v
3.1.1
nawi ~/dev/gulp-tslint which tslint
/usr/local/bin/tslint

~\Development>cat node_modules/tslint/package.json | grep version "version": "3.2.1"

node_modules.bin\tslint -v 3.2.1

Hi, sorry to both again, but I meant the output of tslint -v, not node_modules.bin\tslint -v (I'm not quite sure if they're the same thing for you).

[Chowarmaan]

Sorry, running just tslint gives an error as I did not install it globally, it is only in the project directory which is why I added the second line with the node_modules.bin\tslint -v.

I added typescript and tslint to the global install, and the same error occurs. The tslint -v when installed globally still returns 3.2.1

[panuhorsmalahti]

Can you try again with the latest versions of gulp-tslint and tslint?

[Chowarmaan]

Using the latest version, 3.7.4 has this problem solved. It is working properly.
