Missing no-duplicate-key implementation

[michaeljota]

Bug Report

• TSLint version: 4.0.0-dev0
• TypeScript version: 2.0.3
• Running TSLint via: CLI

Actual behavior

Error:
            Could not find implementations for the following rules specified in the configuration:
            no-duplicate-key
            Try upgrading TSLint and/or ensuring that you have all necessary custom rules installed.
            If TSLint was recently upgraded, you may have old rules configured which need to be cleaned up.

Expected behavior

To have a no-duplicate-key implementation

It's the rule no-duplicate-key have been remove or rename or something?

Yes, it was removed (#885) because this functionality is covered by the compiler now. Sorry I didn't get around to writing the changelog for v4.0.0-dev.0, but you can check out the milestone: https://github.com/palantir/tslint/milestone/26?closed=1

Thanks! Will close this then. 😃

@adidahiya How would one get around this issue if they were using the development branch + using "extends": ["tslint:latest"] in their tslint.json? Is that not possible?

[adidahiya]

@dsifford do you mean 4.0.0-dev.0? It was removed from the built-in configurations in that release too... https://github.com/palantir/tslint/blob/4.0.0-dev.0/src/configs/recommended.ts

@adidahiya Hm.. Let me try again in a bit and report back.

Here's my build from earlier this afternoon that failed after bumping up to @next: https://travis-ci.org/dsifford/academic-bloggers-toolkit/builds/172345309

And here's the commit (you'll see 4.0.0-dev.0 listed in the yarn.lock file): dsifford/academic-bloggers-toolkit@10ab0ba

Let me know if I'm missing something obvious (which is generally the case!)

Also, please extend my thanks to the rest of the Palantir team for all their work on this. Such a critical part of my workflow! 💯 👍

@adidahiya Sorry for the delay.

This is an issue with tslint-microsoft-contrib and it appears to have been resolved in their master branch as of 11 days ago. microsoft/tslint-microsoft-contrib#304

All good now 👍
