Thanks for the report @sanex3339 - can you post a snippet of code that causes this error?

sanex3339 · 2016-06-25T22:37:44Z

TSLint check all files in this directory:

jkillian · 2016-06-25T22:45:41Z

Thanks @sanex3339 and @JonathanPorta, I've filed #1346 which should fix this.

sanex3339 · 2016-06-25T22:46:04Z

thank you!

Closes #1345

JonathanPorta · 2016-06-25T22:47:25Z

Thanks for hopping on this so quick!

jkillian · 2016-06-25T23:11:09Z

New version of TSLint is published, let me know if you run into any other issues!

joshwiens · 2016-07-15T06:51:07Z

@jkillian Running into a slightly different variation of this on both the current published version & @next ( please let me know if you would prefer a new issue as opposed to using the "related-ish" one )

Node : v6.3.0
OSX: 10.11.4

Using the following config ...

    "one-line": [
      true,
      "check-open-brace",
      "check-catch",
      "check-else",
      "check-finally",
      "check-whitespace"
    ],

Exact same stack trace for me. The issue does occur on Travis but not on my local Windows machine. Both running Node 6.

JohannesRudolph · 2016-07-17T15:01:03Z

same issue here. @d3viant0ne should probably open a new ticket, this one is closed.

adidahiya · 2016-07-17T19:40:55Z

Yeah a new ticket would be nice, as well as an isolated code sample where the linter crashes.

joshwiens · 2016-07-18T18:43:08Z

@adidahiya - I'll open a new ticket and get you an isolated example

omelhoro · 2016-10-02T00:34:59Z

I had this issue in the ng2 starter pack using tslint@3.15.1 and traced the error to that file https://github.com/AngularClass/angular2-webpack-starter/blob/master/src/custom-typings.d.ts

I resolved it by commenting out this line

declare module '*';

The error stack:

/Users/igor/dev/own/lang-project/ld-angular-rx/node_modules/tslint/lib/rules/oneLineRule.js:163
        if (body.kind === ts.SyntaxKind.ModuleBlock) {
